List of documentation
1. RAy2 – Microwave Link
The microwave link RAy2 is designed as a high-speed point-to-point wireless bridge for data transmission
under the latest requirements of modern wireless transmission equipment.
RAy2 works with an ethernet interface and can be used in backhaul networks as well as a last-mile
terminal.The design of microwave link RAy2 reflects effort on meeting the strictest criteria of ETSI
standards, particularly for durability against interference, high receiver sensitivity and high output power
to achieve maximum link distance. The native gigabit Ethernet interface is able to cope with full speed
user data throughput at low latency. High availability of the link (up to 99.999%) is able to be achieved
using hitless Adaptive coding and modulation. RAy2 microwave links can also be operated as a Short
Range Device (SRD).
The link properties can be summarised as:
• High data throughput
• Spectrum effeciency
• Robustness
• Security - cofiguration via http, https, ssh
• User friendly interface, advanced diagnostics
Key technical features see Chapter 10, Technical parameters

2. Implementation Notes
2.1. Link calculation
Before a microwave link can be installed, an analysis and calculation of the microwave link must be
made first. The analysis should take place before the site survey itself to get a clear idea about the di-
mensions of the antennas. The analysis consists of the following steps:
• Free space loss calculation
• Link budget calculation
• Rain attenuation
• Multipath fading
• Fade margin
• Fresnel zones calculation
This chapter explains the individual steps and an example of link design is given at the end.
NOTE - For quick reference you can use the calculator on www.racom.eu1
2.1.1. Free space loss calculation
As the electromagnetic waves travel through open space they are attenuated. This attenuation is de-
scribed as Free-space Loss. The loss depends on the distance travelled by signal and its frequency.
Longer distance and higher frequency both mean greater attenuation. Free-space loss can be calculated
thus:
FSL = 32.44 + 20log f+ 20log D
Where:
FSL free-space loss (dB)
ffrequency of the emitted signal (MHz)
Dlength of the link (km)
2.1.2. Link budget calculation
The goal is to design a link producing a received signal stronger than the receiver's sensitivity at the
required BER (typically 10-6). Since every radio signal in earth atmosphere is subject to fading, some
difference between received signal level under normal circumstances and receiver sensitivity is needed
to serve as a fade margin. The minimum value of fade margin can be calculated from the requirement
for link availability (e.g. 99.999% of the time). The required margin depends on the length of the link
as well as other factors such as rain attenuation, diffraction and multipath propagation.
If we ignore the additional loss along the path, the received signal strength can be calculated using the
formula for signal propagation in free space as follows:
PR=PT+GT+GR-FSL
Where
1http://www.racom.eu/eng/products/microwave-link.html#calculation_obsah
RAy2 Microwave Link – © RACOM s.r.o.12
Implementation Notes
PRreceived power level (dBm)
PTtransmitted power (dBm)
GTtransmitting antenna gain (dBi)
GRreceiving antenna gain (dBi)
FSL free space loss (dB)
PRmust be:
PR>PS
Where:
PSreceiver sensitivity (dBm)
The receiver’s sensitivity defines the minimum level of the received signal at which the receiver is able
to process the signal without losses or affecting the transmitted data (for BER better then 10-6).
2.1.3. Fade margin
Determining sufficient fade margin is the most important step in microwave link design. If the margin
is too small, the link will be unstable – as a result, sufficient availability of the link or quality of the
provided services cannot be guaranteed. On the other hand, unnecessarily large margin makes the
link more expensive (higher performance, larger and more expensive antennas) and increases the
cost of creating the microwave link.
The following paragraphs describe the two most significant types of signal strength loss – rain and
multipath attenuation, which are the most frequent along with free space loss. Mutual relation between
rain and multipath attenuation rules out the possibility that the link could be affected by both types of
attenuation at the same time – these types of attenuation do not add up. To determine the fade
margin it is necessary to calculate both rain and multipath attenuation. The larger of the two types of
attenuation determines the value of fade margin. In areas with high precipitation, rain attenuation can
be expected to be more prominent. By contrast, links located in drier climates and little inclination, will
suffer more from multipath attenuation.
2.1.4. Rain attenuation
For frequencies of about 10 GHz rain attenuation starts to become increasingly effective. Precipitation
is not identical in all areas which is why ITU released a recommendation Rec. ITU-R PN.837-1 for
splitting the world into 15 regions according to precipitation intensity see Fig. 2.1, for more detail Ap-
pendix B, Rain zone map. In the areas with higher precipitation greater rain attenuation must be expected
and a greater signal fade margin must be established; see the calculation of link availability.
The following properties are inherent to rain attenuation:
• It increases exponentially with rain intensity
• It becomes significantly larger as the distance travelled increases (>10 Km)
• Horizontal polarization causes greater rain attenuation than vertical polarization
• Rain outage increases dramatically with frequency and path length

Rain attenuation can be calculated using ITU-R outage model, which consists of the following:
Obtain the rain rate R0.01 exceeded for 0.01 per cent of the time (with an integration time of 1 min).
R0.01 values are defined for 15 rain zones and different time percentages and they are given in ITU-R

Compute specific attenuation γR(dB/km) for the frequency, polarization, specific rain rate using ITU-R
recommendation P.838. Rain attenuation for rain rate γR0.01 can be calculated as follows:
γR0.01 = kh,v .R0.01αh,v

Fig. 2.2 shows that rain attenuation is greater for horizontal polarization. In regions with higher precip-
itation the difference in attenuation is more marked. The microwave links RAy17 and RAy24 use both
polarizations, hence the need to consider the worse of the two, i.e. horizontal polarization. When ACM
15© RACOM s.r.o. – RAy2 Microwave Link
Implementation Notes
is active we recommend using horizontal polarization in the direction with lower data traffic (typically
up-link).
2.1.5. Multipath fading
Multipath fading is another dominant fading mechanism. A reflected wave causes a phenomenon known
as multipath, meaning that the radio signal can travel multiple paths to reach the receiver. Typically,
multipath occurs when a reflected wave reaches the receiver at the same time in opposite phase as
the direct wave that travels in a straight line from the transmitter.
Multipath propagation gives rise to two kinds of signal degrading effects, i.e., flat fading and frequency
selective fading. Flat fading is a reduction in input signal level where all frequencies in the channel of
interest are equally affected and is dependent on path length, frequency, and path inclination. In addition,
it is strongly dependent on the geoclimatic factor K.
To calculate the probability of outage due to multipath propagation of microwave links the ITU-R
probability model can be used which describes a single frequency (or narrowband) fading distribution
suitable for large fade depths A in the average worst month in any part of the world (based on ITU-R
P.530-14). The calculation for detailed link design is given as follows [1]:
P0=Kd3.4(1+|εP|)-1.03f0.8×100.00067hL-A/10
where:
dlink distance (km)
ffrequency (GHz)
hLaltitude of lower antenna (m)

2.1.6. Fresnel zones calculation
The position of obstacles between points of the bridge can significantly influence the quality of the mi-
crowave link. The radio signal doesn't only radiate along the line of sight, but also in the area around
it, i.e. in the so-called 1st Fresnel zone. Within this zone 90 % of the energy is transmitted between the
transmitter and receiver antenna. This space has the shape of an ellipsoid. If it is disturbed the link has
poorer transmission properties and a higher quality antenna is required. For this reason the position
of the antenna can be just as important as its height above ground. 60 % of the 1st Fresnel zone is
considered as the most important.

Fig. 2.6: Fresnel zone
The general equation for calculating the first Fresnel zone radius at any point P in between the endpoints
of the link is the following:
Where:
F1first Fresnel Zone radius in metres
d1distance of P from one end in metres
d2The distance of P from the other end in metres
λ wavelength of the transmitted signal in metres
The cross sectional radius of each Fresnel zone is the highest in the center of link, shrinking to a point
at the antenna on each end. For practical applications, it is often useful to know the maximum radius
of the first Fresnel zone. From the above formula, calculation of the first Fresnel zone can be simplified
to:
where:
rmax radius of first Fresnel zone (m)
reducing the radius to 60% get values listed in the following table that define the space particularly
sensitive to the presence of obstacles

30 cm ... 32.2 dBi
60 cm ... 37.8 dBi
99 cm ... 42 dBi
Step 2 - Free space loss calculation
FSL = 32.44 + 20log f+ 20log D= 32.44 + 20log17.2·103+ 20log4 = 129.1 dB
Step 3a - Rain attenuation
For 99.99% availability in rain zone B the rain rate is R0.01=32 (see Fig. 2.1)
For f=17 GHz kh=0.06146; αh=1.0949; kv=0.06797; αv=1.0137
Vertical polarization:
γR0.01 = kv.Rαv0.01 = 0.07 · 321.01 = 2.32 dB/km => for 4km distance 9.3 dB
Horizontal polarization:
γR0.01 = kh.Rαh0.01 = 0.06 · 321.09 = 2.62 dB/km => for 4km distance 10.5 dB
Step 3b - Attenuation due to multipath propagation
We have to find required fade margin for reliability of the link 99.99 percent.
Path inclination:
The percentage of time that fade depth A (dB) is exceeded in the average worst month is calculated
as:
P0=Kd3.4(1+|εP|)-1.03f0.8×100.00067hL-A/10
P0=10-4.6-0.0027×(-300)×43.4(1+|6.25|)-1.0317.20.8×100.032×10-0.00067×295-A/10
P0=0.022871×10-0.19765-A/10
For reliability 99.99% is P0=0.01 we get exponential function for A:
A= -0.19765 - 10log(0.01/0.022871) = 3.4 dB
The minimum fade margin required to suppress multipath fading on this link would be 4 dB.
Step 4 - Choice of Tx power and antennas
Step 5 - and Link budget calculation
Calculation in steps 3a and 3b determines the minimum fade margin required for stable link operation
as 11 dB (rain attenuation is dominant). If you use the maximum performance of antenna with dia-
meter of 30 cm, complete the radio formula as follows:
PR=PT+GT+GR−FSL = 5 + 32.2 + 32.2 − 129.1 = −59.7 dB
Fade margin:
A= |PS|−|PR| = 79 − 59.7 = 19.3 dB
The resulting fade margin is larger than the required 11 dB. Current legislation in the Czech Republic
allows maximum EIRP of +20, i.e. the sum of transmit power and antenna gain at the transmitter
can be 20 dB at the most. For 99cm antennas, TX power can be up to 20 - 42 = -22 dB, the resultant
equation is as follows:
PR=PT+GT+GR−FSL = -22 + 42 + 42 − 129.1 = −67.1 dB
19© RACOM s.r.o. – RAy2 Microwave Link
Implementation Notes
Fade margin:
A= |PS|−|PR| = 79 − 67.1 = 11.9 dB
Fade margin is now only 12 dB which corresponds to link availability > 99.99% of the time in a year.
Technical literature often gives the minimum fade margin of 20 dB. For very long links (more than
10 km) fade margin will, indeed, be approximately 20 dB. For shorter links, however, such large
margin is not necessary. It is helpful to first conduct the calculation above to receive an idea of the
attenuation affecting the link.
The result
To achieve the required transmission capacity and link availability for link distance of 4 km, transmit
power -22 dBm and 99 cm antennas were selected for both sides of the link.

3. Product
RAy2 microwave links enable transmissions in both bands requiring license fees and those that are
free. They work as a point-to-point link in a full duplex setting with transfer speeds of up to 360 Mbps.
Bandwidth can be configured from 1.75 up to 56 MHz. Modulation can be fixed or adaptive and can
be adjusted from QPSK to 256QAM. RAy2 microwave links can also be operated as a Short Range
Device (SRD).
Fig. 3.1: RAy2 – Microwave link
The link is formed by two FOD (Full Outdoor) units. In the case of links operating in the RAy2-17 and
RAy2-24 bands, both units have identical hardware. In the case of links operating in licensed bands,
one unit (labeled L) is transmitting in the Lower and receiving in the Upper part of the band. The other
unit (labeled U) is operating vice versa.
RAy2 links require the use of external parabolic antennas. Parabolic antennas from different producers
are available.
Cross polarization - valid only for links operating in the RAy2-17 and RAy2-24 bands:
One side of the link uses one polarization for transmission (e.g. horizontal) and the opposite polarization
for receiving (e.g. vertical). The other side of the link is turned by 90°. It therefore transmits and receives
using opposite polarizations with respect to the other unit.

3.1. Mounting
Fig. 3.2: RAy2 Microwave link – antenna and FOD unit
The antenna is attached to the mast using a holder adjustable in two planes. The RAy2 unit is then
mounted on the antenna.
There are two possible mounting positions – for horizontal and vertical polarization. Installation and
adjustment of the holder is described in the Section 6.2, “Antenna mounting”.
Note
The RAy2-10 and RAy2-11 units must be mounted with the same polarization while the
units RAy2-17 and RAy2-24 must be mounted with reverse polarity, see Cross polarization.
3.2. Connectors
Each unit is equipped with the following interfaces:
■ ETH1+POE – Gigabit metallic Ethernet port. This port is capable of powering the unit with any
Power over Ethernet power source working according to IEEE 802.3at standard.
■ ETH2 – Slot for user exchangeable SFP module. A wide range of optical modules is available. Both
single or dual mode transceivers can be used. An SFP module with metallic RJ45 interface can
also be used.
The SFP status LED is located just next to the slot.
■ P – DC power connector.
HW button for service purposes.
■ S – USB service connector.
RSS voltage output connectors.
Important
It is strongly recommended to use a high quality SFP module. The SFP modules listed in
Accessories are thoroughly tested by RACOM and are guaranteed to function with RAy2
units. It is possible to use any other SFP module, but RACOM cannot guarantee they will
be completely compatible with RAy2 units.
RAy2 Microwave Link – © RACOM s.r.o.22
Product
The SFP status LED function: The LED status is controlled directly from the SFP module. Its function
is specific for each SFP module. The typical behaviour is an indication of the received signal strength.
Should the signal be in the proper power range (not too strong and not too weak), the LED is shining.
Fig. 3.3: Connectors covered Fig. 3.4: Connectors uncovered
Important
It is recommended that the ETH cable should be grounded at both ends of the connection.
For example, the connector CON-RJ45-UBNT-CAT6 and ETH socket on the control panel
should have a grounded sheath as should the connection to the RAy2 unit.
All bushings and plugs (including the original plugs in the ports) must be fitted with O-rings
and carefully tightened. Otherwise, the unit is not protected against moisture intake and can
not offer guaranteed functionality.
For detailed description see Connectors and Start up.
3.3. Power supply
The microwave unit can be powered either by PoE or a DC power source:
•Standard PoE plus (IEEE 802.3at) power source connected to the “ETH1+POE” connector.
Supported voltage range is 40 — 60 V, distances up to 100 m. Internal RJ45 pins wiring is :
○ (V+) ... 1,2,4,5
○ (V-) ... 3,6,7,8
It is possible to use all 8 pins or only 4 pins. Use:
○ either 4,5 (V+) and 7,8 (V-)
○ or 1,2 (V+) and 3,6 (V-)
○ or both simultaneously
•Any kind of DC power source connected to “P” 3-pin connector.
Supported voltage range is 20 — 60 V.
Important
The microwave unit doesn't support a combination of both power supplies. Only one power
supply can be connected at any one time.
23© RACOM s.r.o. – RAy2 Microwave Link
Product
The internal DC power source uses galvanic separation. If the galvanic separated power source is
used and the DC power line needs to be grounded (either positive or negative wire), the middle pin of
the 3-port DC connector can be used to make a connection between ground and the respective power
wire, see Grounding options (d),(e). If grounding is required it should only be made in one of the following
ways: on the DC power source side or using the 3-port DC connector plugged into the unit.
The next figure shows all available grounding options. We recommend the use of a galvanic separated
power source and no additional DC grounding - see Fig. 3.5, “Grounding options” version c).

5. Step-by-step Guide
The following chapters will guide you step by step through preparation, installation and activation of
the RAy2 link:
• Pre-installation check out
•Installation (Chapter 6, Installation)
•Advanced configuration (Chapter 7, Configuration)
•Troubleshooting (Chapter 9, Troubleshooting)
Pre-installation Checklist
Familiarise yourself with the controls and prepare your configuration ahead of the installation of the
link on the mast tube.
Both units (without antennas) can lie on a desk with flanges running parallel and facing up at an angle;
on a non-metal desk they can also face downward. In the case of units RAy2-17 and RAy2-24 turn the
unit holders so that they are roughly perpendicular to each other. In the case of units operating in licensed
bands (RAy2-10, RAy2-11), turn unit holders so that they are roughly parallel to each other. Use an
ethernet cable to connect each of the units to a PoE source and connect a PC to one of them for con-
figuration.
Take the following steps to establish a connection between the PC and RAy2 and perform a basic
setup.
Fig. 5.1: Link Configuration (RAy2-17, perpendicular holders)
RAy2 Microwave Link – © RACOM s.r.o.36
Step-by-step Guide
Warning
During operation, never bring the waveguides of the stations close to each other. There is
a risk of damaging sensitive input circuits.
5.1. Service access
The RAy2 link is supplied with a default configuration of access parameters:
Unit L has the service IP address 192.168.169.169 and mask 255.255.255.0,
Unit U has the service IP address 192.168.169.170 and mask 255.255.255.0,
access is allowed over HTTP, HTTPS or SSH,
the username is admin and the password is also admin.
On your PC setup an IP address that is within the mask, e.g. 192.168.169.180.
Then open the https configuration interface, e.g.
https://192.168.169.169
Other access options are described in the chapter Configuration - Link settings - Service access of this
manual.
When connection has been established, use the Service access menu to customise access parameters.
Default IP addresses should be replaced with well-chosen operating addresses. Leaving default ad-
dresses in place can lead to network problems later.
The menu contains parameters for the entire link, both for the Local and remote Peer units. If a connec-
tion has been established, both sets of parameters have been set. While working with an isolated unit,
only Local parameters are functional for the currently connected unit.
Note
If the link is OK and there are no parameters shown of the station Peer, it is necessary to
click on Refresh.
Follows the description of basic settings. After entering values on the screen always save the content
by clicking on Apply.
Note
If there is any problem with https certificate after completing the firmware upgrade, please
see the Annex Https certificate for further steps.

Step-by-step Guide
5.1.1. Menu Link settings - General
• Station name – station can be assigned with a name, e.g. the place of installation.
• Station location – for easier inclusion the network hierarchy, it is possible to enter the station’s loc-
ation
Fig. 5.2: Configuration Menu Link settings - General
RAy2 Microwave Link – © RACOM s.r.o.38
Step-by-step Guide
5.1.2. Menu Link - Service access - Services
•IPv4 address – enter a valid IP address to access the drive. The default IP address has to be replaced
with a valid address. Keeping the default address will probably lead to future problems in the network.
• Netmask – enter the network mask.
• Gateway – if necessary, enter a gateway, otherwise leave blank
• Enable access protocols that you are going to need. For security reasons, do not enable more than
is necessary.
• HTTP(S) – allow access to the web interface.
• Telnet – enabling access to the CLI interface using telnet protocol.
• SSH – enabling access to the CLI interface using SSH protocol.
• Management VLAN – Enabling 802.1Q VLAN tag for separation of user and service operations.
• Management VLAN id – Defining 802.1Q VLAN tag for service operations.

•Edit - enter the menu.
•New password – choose a password and enter it.
•Confirm password – enter the password again to confirm.
Fig. 5.4: Configuration menu Link settings – Service access – Services
5.1.4. Menu Maintenance - Feature keys
The firmware of the microwave link is capable of controlling the maximum user data speed. The default
user speed without the feature key is the minimum for the respective hardware unit. The feature key
to assign the maximum user data speed, should be installed prior to physical installation. For further
details see the section called “Feature keys”.
5.2. Basic link configuration
Default radio parameters depend on the specific type of link and the specific channel allocation table.
Channels are typically set in the lower part of the band, the smallest bandwidth, QPSK modulation,
and low power. Both units in the pair should be capable of immediate communication. If it is possible to
work with these radio parameters at the installation location, the link can be activated. On an operating
link the required operating parameters can then be set up.
If a change in the parameters is necessary, it is done in the menu Link settings – Radio and saved by
clicking Apply. This applies when working on both units simultaneously if they are connected, otherwise
each unit is configured individually. When configuring units individually, pay attention to correct settings
of duplex pair for channels TX and RX. For example, if one station has TX channel L1, then the second
station must also have the channel RX L1.
5.3. Link test
Verify the functionality of the radio link:
•Switch in screen Status - Brief.
•Status Bar displays Link: Ok.
RAy2 Microwave Link – © RACOM s.r.o.40
Step-by-step Guide
If the alarm message appears at Local or Peer, this doesn’t necessarily mean there is a problem.
The message indicates that the limit at any of the monitored parameters has been exceeded. Es-
sential is the Link: Ok message on the status bar.
•The Status screen contains values for both Local and Peer units. N/A next to Peer indicates that
the data from the Peer unit has not been transferred. If Link is Ok, simply click Refresh at the bottom
of the screen and Peer data will be updated.
•Menu Status – Detailed – Radio indicates link RSS and SNR values, in case of ACM also the selected
modulation and Netbitrate. If the ATPC function is enabled (menu Link settings – Radio) it also in-
dicates instantaneous / max. allowed power and for SNR and RSS values it indicates immediate /
target value size.
•Menu Tools – Live data – Bar indicators displays current size of RSS, SNR and BER.
•Menu Tools – Ping allows you to send a ping test to the selected IP address.
Try out the possibility of modulation:
•Modulation ACM. In menu Link settings – Radio enable ACM. Set the TX modulation parameter to
the required maximum value. In menu Status – Brief – Radio you can monitor (Refresh or Start)
changes in used modulation based on the instantaneous SNR signal quality. The status and quality
of modulation is demonstrated well in menu Tools – Live data – RX constellation diagram, hit Refresh.
•To set a fixed modulation go to Link settings - Radio, switch off ACM and set the TX modulation to
a value from the range of QPSK through 256-QAM based on the results of the previous test. If you
choose modulation higher than allowed by SNR, the connection will be lost. Status Link will lose its
Ok value. Both units will need to be moved closer to resume the link. If this is not possible, use the
ethernet to access each unit individually and set the basic modulation QPSK. You can monitor the
quality of the received signal under Tools – Live data – RX constellation diagram.
Verify the functionality of the entire link:
• If possible, connect user devices to both RAy2 units over PoE and test mutual communication.
• Another way of testing this is to connect a PC to the other unit and send a ping from one PC to the
other.
• The minimum variant of this test is to use an ethernet cable connection from the PC connected to
the local RAy2 to the PC connected to the remote RAy2 and test communication between both
units over ethernet. This will verify ethernet functionality.
Prepare installation configuration:
•Bandwidth e.g. 3.5 MHz. To get the highest possible receiver sensitivity, set the bandwidth as narrow
as possible according to specific frequency band.
• TX channel: Use your allocated channel. If you don't have allocated channel yet, use for example
channel L1.
• RX channel will setup automatically when channel lock activates.
• Set TX modulation QPSK to get the highest possible sensitivity.
• Set RF power according to selected antenna and according to individual frequency licence. Set the
output power as high as possible.
• Set a new users access passwords.
• Record the access parameters from the Service access menu, especially the IP addresses.
• Restart by interrupting the power supply to verify that the parameters are stored correctly and the
link works.
After this preparation phase you can continue to install your devices in a working environment.

Step-by-step Guide
6. Installation
6.1. Line of sight test
Before you install the device to a mast tube, verify visually that the view in the direction of the remote
unit is unobstructed.
Line of sight considerations:
• Free Fresnel zones. Signal needs space wider than the diameter of the antenna.
• Trees at the lower end of the Fresnel zone. They will be taller in a few years.
• Possible building development.
•Objects in the close proximity of the antenna such as edges of other antennas, their mounting racks,
edges of the roof.
6.2. Antenna mounting
6.2.1. Mounting methods
• Mounting on the mast tube can be achieved by:
○ right-side mounting or
○ left-side mounting
• Mounting the FOD unit for antenna polarization can be achieved using:
○ horizontal RX polarization mounting or
○ vertical RX polarization mounting
In both cases mount the unit with the connectors facing downwards at an angle.

Installation
Changing the mounting method
An antenna bracket is supplied as standard partly assembled, and ready for right-side mounting.
On changing the Jirous antenna bracket for left-side mounting the adjustment bolt (part No. 11) and
swivel bolt (part No. 6) need to be unscrewed, then shift the bracket body (part No.5) to the other side
of clamp plate (part No. 4), (do not turn upside down) and then insert bolt (part No. 6) into the second
hole on the mounting plate holder and through the same hole on the clamp plate and secure in place
with the nuts. The adjustment bolt (item No. 11) and nuts are switched to the other side of the clamp
plate (part No. 4). It is also necessary to switch the hanging bolt (part No. 7) on the antenna mounting
plate to the second hole so that after switching sides with the antenna it is on the top again.
In the case of the antenna when changing the method of mounting from right-side to left-side it is only
necessary to rotate the plastic cover of the antenna. This is not only important from an aesthetic point
of view, so that the RACOM logo is not upside down, but also because there is a discharge channel
on the lower edge of the dish (except for ø380 mm dishes).
Fig. 6.6: Changing the mounting method
When changing the polarization from horizontal to vertical only the FOD unit needs to be turned through
90° around the central antenna pin by unscrewing the four bolts on the dish using a No. 6 Allen key.
Important
The RAy2-17 and RAy2-24 links are equipped with a polarization duplexer and work in both
polarizations simultaneously, see Cross polarization. One side of the link must therefore
be installed in vertical polarization and the other in the horizontal polarization.
RAy2 Microwave Link – © RACOM s.r.o.44
Installation
6.2.2. Mounting the FOD unit on the antenna
RAy2 microwave bridge equipment is generally supplied as several component parts packaged separ-
ately in a box.
• Two parabolic antennas with assembled mounting plates. There are also 4 screws in a small plastic
bag in the box.
• Two brackets for mounting the antenna to the mast.
• Two FOD stations, each separate in a box, in a single package.
• Other accessories based on the order placed (for more detailed information see chapter Chapter 4,
Accessories)
A No. 17 spanner and a No. 6 Allen key are required for mounting the mechanical parts of the antenna.
Spanner No. 17 serves for precisely setting the direction of the antenna. Both spanner and key can be
found in the RAy Tool set for installing RAy2 microwave bridges.
It is advisable to lightly lubricate the retaining screws eg. by the supplied grease.
Fig. 6.7: Close up image of the mounted bracket showing numbered parts
a. Prepare the antenna bracket based on the diameter of the mast tube. For smaller diameters face
the bent part of the saddle plate (part No. 3) inwards. For larger diameters it should face outwards.
Screw the bolts (part No. 1) into the clamp plate (part No. 4) so that they protrude approx. 1 cm
through the clamp plate. Clamp the saddle plate to the mast by tightening the nuts (part No. 2) on
the bolts.
Fig. 6.8: Position of the saddle plate for
ø 40–80 mm
Fig. 6.9: Position of the saddle plate for

Installation
b. Slide the antenna bracket onto the mast tube and clamp to the mast by tightening the nuts.
Recommendation: Keep the gap between the two saddle plates (part No. 3) as wide as possible,
so the horizontal angle adjustement screw can fit in this gap. The range of horizontal adjustement
is consequently wider. This has a bigger effect when the mast diameter is smaller.
Fig. 6.10: Attaching the bracket to the mast tube Fig. 6.11: Bracket on the mast tube
c. Screw the hanging bolt (part No. 7) into the upper hole of the mounting plate so that the antenna
can be hung on the mounting plate holder. Hang the antenna on it and tighten the lower bolt. (part
No. 8)
Fig. 6.12: Hanging the bolt on the holder Fig. 6.13: Correct position of the mounting plate

Installation
d. Tighten both bolts to the plate before continuing with installation to prevent any unnecessary
movements of the equipment. Before precisely adjusting the vertical direction of the antenna upon
completing installation it will be necessary to unscrew them again as the lower bolt (part No. 8)
passes through the adjustment block and the upper one (part No. 7) serves as the axis of rotation.
Fig. 6.14: Tightening the upper bolt to
the mounting plate
Fig. 6.15: Tightening the lower bolt to
the mounting plate
e. Before installing the FOD unit on the antenna first unscrew the 4 bolts on the back of the antenna
enough so that the unit can be slid on to them. Then check whether the "O" ring is correctly fitted
on the antenna pin, and make sure it is not damaged and has been lubricated with grease – see
Section 6.2.3, “Lubrication and preservation of the antenna pivot”. Then remove the protective
plastic cover from the central pin of the antenna and fit the FOD unit to it carefully so as not to
damage the "O" ring. Secure it in place with the four bolts. Carefully ensure the correct polarization
of the antenna – see Section 6.2.1, “Mounting methods”. Finally tighten the bolts with a No. 6 Allen
key.

Installation
f. The precise horizontal direction the antenna is pointing in can be adjusted using the bolt with two
nuts (part No. 10 and 12). Once the direction has been set the antenna is fixed in place by tightening
the nuts against the bracket to prevent further movement of the antenna. The vertical direction the
antenna is pointing in can be adjusted by turning the fine adjustment bolt (part No. 9) by the
bracket mounting plate. After selecting the correct direction the position is secured by tightening
the bolt – see point d. (part No. 7 and 8). The correct position in both directions is found by monit-
oring RSS voltage, see Section 6.5.2, “Directing antennas”.
Fig. 6.18: Horizontal adjustment of the
antenna direction
Fig. 6.19: Vertical adjustment of the
antenna direction
g. After pointing the antenna in the right direction tighten the bolts on the bracket on the axes of rotation
(part No. 6 and 11). Then check again that all other bolts have been sufficiently tightened. We can
now proceed to connect the FOD unit to the user network.

Installation
6.2.3. Lubrication and preservation of the antenna pivot
Before fitting the FOD unit bush onto the antenna pivot ensure that the "O" ring (part No. 1) is in the
correct position. It is also essential to prevent moisture getting in between these two parts. This moisture
could cause oxidation which would complicate disassembly of this mechanical coupling in the future.
For this reason we need to treat these surfaces with the grease which is supplied in the box marked
"SILIKONOVE MAZIVO". If you use a different grease for lubrication then it should be a Teflon or a
silicon grease.
Fig. 6.22: Grease points on the antenna pivot and FOD unit bush
Grease the internal area of the bush on the FOD unit (2) and the "O" ring (1) with a thin even layer that
allows the pin to slide easily into the bush without damaging the "O" ring. Grease the area beyond the
"O" ring on the antenna pin (3) with a thicker layer so that it fills the gap caused by the play between
the pin and the bush (max. 0.1 mm/ø) thus preventing moisture getting in. Installation should be carried
out according to the antenna installation description – see point f of this description.
The tub with grease is supplied with the RAy2 units.
6.2.4. Flexible waveguide
Any type of antenna may be connected to the RAy2 unit using a flexible waveguide. Flexible waveguide
mounting kit can be ordered as an accessory part.
Fig. 6.23: Flexible waveguide assembly

Installation
6.3. Connectors assembly
The FOD communication unit can be connected to the user network by metallic or fibre Ethernet cable.
The unit is equipped with those connectors:
■ ETH1+POE – Gigabit metallic Ethernet port. This port can power the unit with any Power over
Ethernet power source working according to IEEE 802.3at standard.
■ ETH2 – Slot for user exchangeable SFP module. A wide range of optical modules is available. Both
single or dual mode transceivers can be used. The SFP module with metallic RJ45 interface can
be used as well. Please see the Important notice.
The SFP status LED is located just next to the slot.
■ P – DC power connector.
HW button for service purposes.
■ S – USB service connector.
RSS voltage output connectors.
Fig. 6.24: FOD communication unit connectors
Important
Before connecting the FOD communication unit to the supply (to the user network) the FOD
unit must be grounded according to Section 6.4, “Grounding”.

The rubber sealing is delivered with three different internal diameters to fit different cable diameters.
The rubber is diagonally cut to enable sealing of cables with preinstalled connectors.
Important
All bushings and plugs (including the original plugs in the ports) must be fitted with O-
rings and carefully tightened. Failure to do so may result in moisture accessing the in-
ternal workings. In such a situation the functionality cannot be guaranteed.
•
• Before screwing extension ring (part No.6) into the RAy2 housing, lubricate its thread
with grease.
• When using other bushing or connector than the delivered there is a danger of bad seal
or damaging the connector. Interior space can be small.
6.4. Grounding
The lightning and overvoltage protection system example, designed in accordance with regulation CSN
EN 62305.
1. Where possible the antenna should be located in an LPZ 0B protection zone with the use of a
local or artificial air termination device for protection against direct lightning strikes.
2. When meeting conditions for ensuring electrical insulation (distance from the lightning conductor)
in accordance with article 6.3, it is not recommended to ground the load-bearing structure and
antenna to the external air termination network. Grounding should be attached to the protective
system of the internal LV wiring or grounded internal structures using a CYA 6 mm2bonding con-
ductor , see Fig. 6.28, “Grounding installation 1”

3. If it is not possible to set up conditions of electrical insulation in accordance with article 6.3 we re-
commend connecting the load-bearing structure at roof level to the external air termination network
via an 8mm diameter FeZn conductor and shielding the data cable before entry to the building
with a grounding kit and CYA 6 mm2conductor to the bonding bus, and if not already set up then
also to the external air termination network, see Fig. 6.29, “Grounding installation 2”
4. If there is not an external LPS on the building we recommend routing lightning current through an
8mm FeZn conductor to a common grounding system, or to a separate grounding electrode with
a ground resistance up to 10 Ω.
5. For limiting the overvoltage transferred over the data cable and into the building we recommend
fitting surge protection at the interface between zones LPZ 0 and LPZ 1 connected via a CYA 4
mm2conductor to the same grounding point as the antenna or the antenna mast.
6. We recommend protecting the PoE power supply from overvoltage on the LV side with suitable
class D surge protection.
The RAy2 unit is grounded to the flange at the fixing screws using an M8 screw. An insulated copper
cable with a minimum cross-section of 6 mm2terminated with a terminal lug is used as a protective
conductor. The conductor should have a green/yellow plastic cover along its whole length. For
grounding a RAy grounding kit can be ordered as an accessory (see Chapter 4, Accessories) containing
a grounding terminal ZSA16, 40 cm grounding strip 15 mm wide, and 100 cm of cable with grounding
lugs. For instructions on installing terminals see the datasheet RAy grounding kit1. A qualified person
must install the antenna.
Racom supplies surge protection for installation on Ethernet cables entering buildings. For more details
see Surge protection2.
Additional safety recommendations
• Only qualified personnel with authorisation to work at heights are entitled to install antennas on
masts, roofs and walls of buildings.
• Do not install the antenna in the vicinity of electrical wiring. The antenna and bracket should not
come into contact with electrical wiring at any time.
• The antenna and cables are electrical conductors. During installation electrostatic charges may
build up which may lead to injury. During installation or repair work to parts of the antenna lead,
bare metal parts must be temporarily grounded.
• The antenna and antenna cable must be grounded at all times. See Section 6.4, “Grounding”.
• Do not mount the antenna in windy or rainy conditions or during a storm, or if the area is covered
with snow or ice.
• Do not touch the antenna, antenna brackets or conductors during a storm.

Installation
6.5. Start up
Connect a power supply to the installed FOD unit and connect the configuration PC. Use an internet
browser (such as Mozilla Firefox) to enter the configuration menu.
6.5.1. Noise on the site
This is particularly true for installation of links working in free bands, where the user has no secured
frequency.
Analyse the level of noise in the individual channels using the spectrum analyzer under Tools – Live
data – Frequency spectrum analyzer. If necessary adjust the choice of working channel on the basis
of the results.
While doing so respect the rule that in one location all units emit a signal in the Upper part of the range
and receive it in the Lower part of the range, or the other way round. A transmitter must not be installed
in the part of the spectrum where other units function as receivers.
6.5.2. Directing antennas
If it is possible, use a narrow channel, low modulation and high power for the first antenna directing
alignment. Working on both ends of the link simultaneously is favourable. Connect a voltmeter to the
connectors and observe RSS changes in 2 V DC range. A stronger signal corresponds to lower voltage.
Alternate units on both sides and slowly adjust the antenna vertically and horizontally to find the position
with the strongest reception. At the same time look for the main signal maximums. To differentiate
between the main and the side maximums refer to the Main and side lobes paragraph.
RSS measurement
For correctly setting the bridge and positioning it in the right direction it is advisable to connect a PC
and use the diagnostic capabilities of the RAy2 station. In uncomplicated cases it is enough to connect
a voltmeter via connectors and adjust to the lowest indicated voltage. Voltage is calibrated according
to signal strength. E.g.:
RSS -65 dBm corresponds to voltage 0.65 V,
RSS -80 dBm corresponds to voltage 0.80 V etc.

Main and side lobes
Directional antennas have a specific angle within which radio waves can be transmitted or received
(Angle of Tx/Rx).
The strongest signal is emitted in a forward direction; the main lobe is a graphical representation of its
direction of travel and strength.
However signals are also emitted and received from unwanted directions through side lobes. In receiving
antennas this is a highly significant factor contributing to the level of interference in a radio network
(See Fig. 6.40, “Antenna lobe diagram”).
Fig. 6.41, “Signal strength graph” provides an indication of comparative signal strength from different
beams emitted from a directional antenna.

Fig. 6.43: Radiation diagrams
Both antennas should be oriented towards each other using the peaks of the radiation diagram. Adjust
the antenna alternately in the horizontal and vertical axes and monitor the resulting signal strength.
Use the calculation of the expected RSS with the precision of several dBm as guidance. Side lobes
transmit a signal ca 20 dBm weaker, see the Microwave link Calculation3.

The resulting RSS helps distinguish between
the states A-A and C-C which appear similar.
It also helps in situations where simple search
for a maximum doesn’t work as shown in the
illustration “incorrect adjustment”.
Real radiation diagrams are more complex,
especially in that they run differently in horizont-
al and vertical axes. The basic steps for determ-
ining the main radiation lobe however stay
valid. For example:

6.5.3. Link test
Basic parameters of the link are shown in the menu Status – Brief, its quality is characterized by RSS
and SNR. Values on Status screens can be refreshed manually by pressing the Refresh button or
in real time with a period of several seconds after activating the Start button. Press the Stop button to
terminate the periodic refresh of values.
The RSS, SNR and BER values can also be viewed on the screen Tools – Live data – Bar indicators.
After pressing the Start button, values will be refreshed with a period of one second.
After installation, it is good to reset the statistics using the Clear stats button in menu Status – Detailed.
This allows easier diagnostics of the link’s reliability over time.
6.5.4. Parameters setup
After both antennas have been aligned, setup operation parameters for the link. In the case of links
operating in the free band, setup the parameters based on survey results from the tool Tools – Live
data – Frequency analyser. In the case of links operating on a licensed band, setup the parameters
based on the assigned license:
• Bandwidth
• Channel Selection (TX / RX channel)
•Modulation (TX modulation) – ACM is recommended. When selecting fixed modulation it is necessary
to account for the fade margin. If fixed modulation is setup close to a possible maximum, then a
deterioration in RSS could endanger the link both for data transfer as well as service access.
• Transmit power (TX power), or ATPC
• Verify and record IP addresses
• Define access channels – https / telnet / ssh / ssh with password
• Check the users password settings.
Restart both units by interrupting their power supply and verify the status of the link. This verifies that
all parameters have been stored correctly in the memory.
Select Tools – Maintenance – Backup – Settings (Local & Peer) - Download and save the configuration
to backup file “cnf_backup.tgz”.
This completes the installation. Further configuration can be performed remotely.

link: standard and direct
Service
channel
standard:
Both units are configured with the separate IP addresses, Netmasks, Gateways and
Management VLANs. IP addresses of both units doesn't have to belong in to the
same sub-net. The Internal VLAN is required to encapsulate the internal service traffic
between both units of the microwave link. There are additional internal service ad-
dresses used for this internal service traffic (see IPv4 address - Local section for
further details).

direct:
Both units are configured with the separate IP addresses but with the same Netmask,
Gateway and the Management VLAN. IP addresses of both units must belong in
to the same sub-net. There is no need for Internal VLAN to handle the internal service
traffic between both units of the microwave link. No additional internal service ad-
dresses exist.
NOTE: It is strongly recommended to use Management VLAN to encapsulate and
prioritize the management traffic when the direct mode is selected. If the Management
VLAN is not used (while in direct mode), the internal service traffic is NOT prioritized.
Service IP address, by default 192.168.169.169 for L unit and 192.168.169.170 for U

Auto negotiation Auto-Negotiation is an Ethernet procedure by which two connected devices choose
common transmission parameters, such as speed, duplex mode and flow control.
In this process, the connected devices first share their capabilities regarding these
parameters and then choose the highest performance transmission mode they
both support.
The device supports three types of Auto-Negotiation:
10/100/1000BASE-T Copper Auto-Negotiation. (IEEE 802.3 Clauses 28 and
40)
1000BASE-X Fiber Auto-Negotiation (IEEE 802.3 Clause 37)
SGMII Auto-Negotiation (Cisco specification)
Auto-Negotiation provides a mechanism for transferring information from the local
unit to the link partner to establish speed, duplex and Master/Slave preference
during a link session.
Auto-Negotiation is initiated upon any of the following conditions:
Power up reset
Hardware reset
Software reset
Restart Auto-Negotiation
Transition from power down to power up
The link goes down
The 10/100/1000BASE-T Auto-Negotiation is based on Clause 28 and 40 of the
IEEE 802.3 specification. It is used to negotiate speed, duplex and flow control
over CAT5 (or higher) UTP cable. Once Auto-Negotiation is initiated, the device
determines whether or not the remote device has Auto-Negotiation capability. If
so, the device and the remote device negotiate the speed and duplex with which
to operate.
If the remote device does not have Auto-Negotiation capability, the device uses
the parallel detect function to determine the speed of the remote device for
100BASE-TX and 10BASE-T modes. If a link is established based on the parallel
93© RACOM s.r.o. – RAy2 Microwave Link
Configuration
detect function, it is then required to establish the link at half-duplex mode only.
Refer to IEEE 802.3 clauses 28 and 40 for a full description of Auto-Negotiation.
1000BASE-X Auto-Negotiation is defined in Clause 37 of the IEEE 802.3 specific-
ation. It is used to auto-negotiate duplex and flow control over fibre cable.
If the PHY enables 1000BASE-X Auto-Negotiation and the link partner does not,
the link cannot linkup. The device implements an Auto-Negotiation bypass mode.
SGMII Auto-Negotiation. SGMII is a de-facto standard designed by Cisco. SGMII
uses 1000BASE-X coding to send data as well as Auto-Negotiation information
between the PHY and the MAC. However, the contents of the SGMII Auto-Negoti-
ation are different than the 1000BASE-X Auto-Negotiation.
WARNING: If one device provides Auto-negotiation and the other works with a
manual link parameters settings (i.e. without Auto-negotiation) the link operates
in half-duplex mode. If the manual settings is set to full-duplex, the Out collisions
may occur.
Speed / duplex Ethernet link speed and duplex mode can be selected. Both parameters can be
either auto negotiated or set manually. When the Auto negotiation parameter is
disabled, only manual setting of the speed and duplex is possible. In most cases
it is better to enable the auto negotiation and use "auto / auto" speed and duplex
settings.
There are two possibilities to force the link to operate in specific speed and duplex:
Auto negotiation enabled. Select the desired Speed / duplex. The auto negoti-
ation process advertises only this specified link mode. The link partner is asked
to use it.
Auto negotiation disabled. Select the desired Speed / duplex. The link is set to
this specified link mode. The link partner has to be set manually to the same
mode.
Flow control The flow control mechanism is handled by sending Pause frames to the connected
device. There are several modes of Pause frames generation:
Pause frames disabled.no pause
Pause frames transmission and reception enabled.symmetric
Pause frames transmission enabled, reception disabled.asymmetric
(send)
Pause frames reception enabled, transmission disabled.asymmetric
(receive)
Auto-Negotiation has to be enabled to enable Pause frames sending and receiving.
Force

control parameter can be used. Flow control is turned on without having to be Auto-

own by detecting activity on the Ethernet cable. The energy detect modes only
apply to the copper media.
In the first sense mode, if the PHY detects energy on the line, it starts to Auto-Ne-
gotiate sending FLPs (Fast Link Pulse) for 5 seconds. If at the end of 5 seconds
the Auto-Negotiation is not completed, then the PHY stops sending FLPs and goes
back to monitoring received energy. If Auto-Negotiation is completed, then the PHY
goes into normal 10/100/1000 Mbps operation. If during normal operation the link
is lost, the PHY will re-start Auto-Negotiation. If no energy is detected after 5
seconds, the PHY goes back to monitoring received energy.
In sense pulse mode, the PHY sends out a single 10 Mbps NLP (Normal Link Pulse)
every one second. Except for this difference, this is identical to the previous mode
(sense) operation. If the device is in sense mode, it cannot wake up a connected
device; therefore, the connected device must be transmitting NLPs. If the device
is in sense pulse mode, then it can wake a connected device.

Frame mode Ethernet Frame mode control defines the expected Ingress and the generated Egress
tagging frame format for this port as follows:
Normal Network mode uses industry standard IEEE 802.3ac Tagged
or Untagged frames. Tagged frames use an Ether Type of 0x8100.
normal
Ports that are expected to be connected to standard Ethernet devices
should use this mode.
Inactive options are not required.DSA
Provider mode uses user definable Ether Types per port (see Ether
type parameter) to define that a frame is Provider Tagged. Ports that
provider
are connected to standard Provider network devices, or devices that
use Tagged frames with an Ether Type other than 0x8100 should use
this mode.
Frames that ingress this port with an Ether Type that matches the port's
Ether Type parameter will be considered tagged, will have the tag's
VID and PRI bits assigned to the frame (i.e. they will be used for
RAy2 Microwave Link – © RACOM s.r.o.96

switching and mapping), and will have the Provider Tag removed from
the frame. If subsequent Provider Tags are found following the 1st
Provider Tag, they too will be removed from the frame with their VID
and PRI bits being ignored. Modified frames will be padded if required.
Frames that ingress this port with an Ether Type that does not match
the Ether Type parameter will be considered untagged. The ingressing
frames are modified so they are ready to egress out Customer ports
(Normal Network Frame Mode ports) unmodified.
Frames that egress this port will always have a tag added (even if they
were already tagged). The added tag will contain this port's Ether Type
as its Ether Type. The PRI bits will be the Frame Priority FPri assigned
to the frame during ingress. The VID bits will be the source port's Default
VID bits (if the source port was in Normal Network mode), or the VID
assigned to the frame during ingress (if the source port was in Provider
mode).
Valid only for the "p5 CPU" port.ether
type DSA Ether Type DSA mode uses standard Marvell DSA Tagged frame in-
formation following a user definable Ether Type (see Ether type para-
meter). This mode allows the mixture of Normal Network frames with
DSA Tagged frames and is useful on ports that connect to a CPU.
Frames that ingress this port with an Ether Type that matches the port's
"Ether Type" will be considered DSA Tagged and processed accordingly.
The frame's Ether Type and DSA pad bytes will be removed so the
resulting frame will be ready to egress out Marvell DSA Tag Mode ports
unmodified. Frames that ingress this port with a different Ether Type
will be considered Normal Network Frames and processed accordingly.
Marvell DSA Tag control frames that egress this port will always get
the port's "Ether Type" inserted followed by two pad bytes of 0x00 before
the DSA Tag. Marvell DSA Tag Forward frames that egress this port
can egress just like the control frames (with the added Ether Type and
pad) or they can egress as if the port was configured in Normal Network
mode. This selection is controlled by the port's Egress Mode bits above.
Frame type Ethernet frame type (often called EtherType) is used to indicate which protocol is
encapsulated in the payload of an Ethernet Frame. This parameter is important when
one protocol is encapsulated to another protocol.
Examples:

received from a given input port but may or may not be allowed to be transmitted out
of a port or ports. The possible values are 1522, 2048 and 10240 Bytes.
NOTE: The definition of frame size is counting the frame bytes from MAC_DA
through Layer2 CRC of the frame.
Pause limit in
[frame] Limit the number of continuous Pause refresh frames that can be received on this
port (if full-duplex) or the number of 16 consecutive collisions (if half-duplex). When
a port has flow control enabled, this parameter can be used to limit how long this port
can be Paused or Back Pressured off to prevent a port stall through jamming.
The Flow Control on the port is (temporarily) disabled when the Pause refresh frames
count exceeds the value of this parameter.
Setting this parameter to 0 will allow continuous jamming to be received on this
port.
Pause limit out
[frame] Limit the number of continuous Pause refresh frames that can be transmitted from
this port – assuming each Pause refresh is for the maximum pause time of 65536
slot times. When full-duplex Flow Control is enabled on this port, this parameter is
used to limit the number of Pause refresh frames that can be generated from this
port to keep this port’s link partner from sending any data.
Clearing this parameter to 0 will allow continuous Pause frame refreshes to egress
this port as long as this port remains congested.
Setting this parameter to 1 will allow 1 Pause frame to egress from this port for
each congestion situation.
Setting this parameter to 2 will allow up to 2 Pause frames to egress from this
port for each congestion situation, etc.
Ignore Frame
checksum Ignore Frame checksum (FCS) - or in other words - Force good FCS in the frame. When
this parameter is not set (default behaviour), frames entering this port must have a good
CRC or else they are discarded. When this parameter is set, the last four bytes of frames
received on this port are overwritten with a good CRC and the frames are accepted by
the switch (assuming that the frame’s length is good and it has a destination).

Frame
The frame comes via port, has a certain length and MAC addresses SA and DA. The IP header carries
the DSCP priority and may also carry the 802.1p VLAN priority.
QoS
The Queue priority (QPri) is created based on preferences within the DSCP or 802.1p priority. This
priority takes values from 0 to 3, and controls the processing of frames inside the switch.
• Untagged frames are provided with 802.1p priority by default.
• Priorities may be remapped.
• The priority can also be overwritten by the Advanced menu priority derived from a VLAN, SA and/or
DA addresses.
The Frame priority (FPri) is processed in a similar manner. Frame coming from the network and frame
being sent to the network is marked by this priority.
PIRL
Between the port and the common switch there may be between 1 and 5 “flow restrictors” working in
parallel according to the schedule “leaky bucket”. These are called “Resource”. This is analogous to
99© RACOM s.r.o. – RAy2 Microwave Link
Configuration
the container which is intermittently replenished by tokens according to incoming frames and is continu-
ously emptied. Regulatory measures are implemented at a certain height to ensure the bucket does
not overflow.
PIRL - Edit section of this menu is made up of several groups of parameters:
• Resource identification.
• Resource capacity, transfer byte into tokens.
• Method of counting frames.
• Regulatory interventions (drop frame - reduce feeding)
• Selecting frames (all - by priority QPri - by type).
The above mentioned parameters are used to allocate part of a frame to each Resource. Their passage
is regulated thus avoiding network congestion. If there is a framework that does not match the filter of
any Resource, this then passes to the switch without restrictions.
Switching block
In this block (L2-switch) each frame is routed to a designated port according to the Advanced menu.
Egress queue
Block output queues. Each port receives frames from the L2 switch through 4 queues (No. 3-0). The
highest priority has a queue No. 3. The frames are organized into queues according to their priorities
QPri.
The Method to empty queues is selected by the parameter Scheduling Mode. The emptying rate is
governed by the Rate limit parameter.
A Frame sent from the port to the network can be identified by priority FPri, although it is also possible
to change its tag: see menu VLAN - Egress mode.

Port based ingress rate limiting, see also the Functional diagram
Fig. 7.25: Menu Switch settings - PIRL
The device supports per port TCP/IP ingress rate limiting along with independent Storm prevention.
Port based ingress rate limiting accommodates information rates from 64 Kbps to 1 Mbps in increments
of 64 Kbps, from 1 Mbps to 100 Mbps in increments of 1 Mbps and from 100 Mbps to 1000 Mbps in
increments of 10 Mbps.
In addition to this, the device supports Priority based ingress rate limiting. A given ingress rate resource
can be configured to track any of the four priority traffic types. One of the popular schemes for imple-
menting rate limiting is a leaky bucket. The way a leaky bucket scheme works is that the bucket drains
tokens constantly at a rate called Committed Information Rate (CIR) and the bucket gets replenished
with tokens whenever a frame is allowed to go through the bucket. All calculations for this bucket are
done in tokens. Therefore, both bucket decrementing and incrementing is performed using tokens (i.e.,
frame bytes are converted into bucket tokens for calculation purposes).
The device supports a color blind leaky bucket scheme.
The traffic below Committed Burst Size limit (CBS Limit) is passed without any further actions. If the
traffic burst were to continue and the bucket token depth approaches closer to the Excess Burst Size
limit (EBS Limit) by less than the CBS Limit, then a set of actions are specified. Note that if the frame
gets discarded then the equivalent number of tokens for that frame will not get added to the bucket.
There are the two default ingress limiting rules already configured in the switch default configuration.
They limit the maximum allowed ARP traffic comming to the CPU port to 10Mbps from Eth1 and 10Mbps
from Eth2 ports.

The calculation is estimated as the real data throughput depends on frame size.

Burst allocation
[b] The Burst allocation (BA) is dependent of the Bucket increment, the Committed
Burst Size limit and the Excess Burst Size limit.
The formula for the BA is as follows: BA = 8 * (EBS-CBS) / BI.
Where EBS is the Excess Burst Size limit, CBS is the Committed Burst Size limit
and BI is the Bucket increment.
The Burst allocation size should be less than switch internal memory which is 1Mb.
CBS min The minimum value for the CBS limit is related to the maximum frame size and
Bucket increment.
The CBS limit should always be bigger than the CBS min.
The calculation for CBS min is as follows:
CBS min = BI * MaxFrameSize [bytes].
Where BI is the Bucket increment.
If the CBS limit is lower than this value (i.e. to allow a large burst), then an ingress
stream composed of maximum sized frames may exceed the Committed Information
Rate. It is for this reason that we recommend the CBS limit value always stays
above the CBS min value. Also, the CBS limit should never exceed the EBS limit.
EBS limit Excess Burst Size limit.
The EBS limit should always be bigger than CBS limit. It is recommended that the
EBS limit be set to 16777200.
CBS limit Committed Burst Size limit. This indicates the committed information burst amount.

Account
discarded
frames
This parameter decides whether the ingress rate limiting logic accounts for frames
that have been discarded by the queue controller due to output port queue conges-
tion reasons. To account for all frames coming into a given port associated with
this rate resource, this parameter needs to be set.
Account filtered
frames This parameter decides whether the ingress rate limiting logic accounts for frames
that have been discarded because of ingress policy violations. To account for all
frames coming into a given port associated with this rate resource, this parameter
needs to be set.
Management
non rate limit When this parameter is disabled all frames that are classified by the ingress frame
classifier as MGMT frames would be considered to be ingress rate limited as far
as this particular ingress rate resource is concerned.
When this parameter is enabled, all frames that are classified as MGMT frames
by the ingress frame classifier would be excluded from the ingress rate limiting
calculations for this particular ingress rate resource.
SA non rate limit When this parameter is enabled then SA ATU non rate limiting overrides can occur
on this port. An SA ATU non rate limiting override occurs when the source address
of a frame results in an ATU hit where the SA's MAC address returns an "Entry
state" with "static non rate limiting" value. When this occurs the frame will not be
ingress rate limited.
DA non rate limit When this parameter is enabled then DA ATU non rate limiting overrides can occur
on this port. A DA ATU non rate limiting override occurs when the destination ad-
dress of a frame results in an ATU hit where the DA's MAC address returns an
"Entry state" with "static non rate limiting" value. When this occurs the frame will
not be ingress rate limited.
Accounted
bytes This parameter determines which frame bytes are to be accounted for in the rate
resource's rate limiting calculations.
There are for different supported configurations:
Frame based configures the rate limiting resource to account for
the number of frames from a given port mapped to this rate re-
source.

A frame is considered tagged if it is either Customer of Provider tagged during in-
gress.
EBS limit action This parameter controls what kind of action is performed when the EBS limit has
been exceeded. Three types of action can be selected:
The frame that was received on the port will get discarded.drop

In this mode an Ethernet flow control frame gets generated (if the
flow control is enabled for that port) and sent to the source port

but the incoming frame gets passed through the rate resource. If
the port is operating in half-duplex mode then the port gets jammed.
The frame that was received on the port is accepted even though
there are not enough tokens to accept the entire incoming frame.
accept
This mode is expected to be selected for TCP based applications.
It is not recommended for media streaming applications where
data timing is critical.
Flow control mode is expected to be programmed on ports that have a trusted flow
control mechanism available. The EBS limit action is a per-port characteristic. If a
port has multiple rate resource buckets then all buckets enabled are expected to
be programmed with the same EBS limit action.
Sampling mode This mode is used for sampling one out of so many frames/bytes that are being
monitored. The stream could be identified by the ingress engine as a Policy mirror
and packet sampling can be applied for that streeam using one of the rate resources.
In this mode, once the rate resource's "EBS Limit" is exceeded, the next incoming
frame from this port that is assigned to this resource gets sent out to the mirror
destination. After sending a sample frame, the token count within the rate resource
is reset to zero and the bucket increments continue for each subsequent frame
arrival.
The sampling mode is useful for limiting the number of Mirror frames sent to the
mirror destination.
Flow control
de-assertion This parameter controls the flow control de-assertion when EBS limit action is set
to generate a flow control message. There are two modes available:
Flow control gets de-asserted only when the ingress rate resource
has become empty.
empty
Flow control gets de-asserted when the ingress rate resource has
enough room to accept at least one frame of size specified by the
CBS limit.
For example, if the CBS limit is programmed to be 2k Bytes, then
the flow control will get de-asserted if there is at least 2k Bytes
worth of tokens available in the ingress rate resource.
CBS limit
Bucket type Any given bucket can be programmed to be aggregate rate based or traffic type
based.
Rate based ingress rate limit: Limits all types of traffic on the ingress port.
Traffic type based ingress rate limit: Limits a specific type of traffic on the ingress
port.
Mask operation This parameter controls whether an ingress frame must meet both Priority and
Frame type requirements to be counted for ingress rate calculations or if meeting
only one requirement is sufficient to be counted for ingress rate calculations for
this rate resource.
Priority Any combinations of the four queue priorities can be selected. Frames with marked
priority are accounted for in this ingress rate resource.
If there is no priority selected, priority of the frame doesn't have any affect on the
ingress rate limiting calculations done for this ingress rate resource.

Scheduling
mode Port's Scheduling mode.
The device supports strict priority, weighted round robin, or a mixture on a per
egress port selection basis.
In the strict priority scheme all top priority frames egress for a port until that priority’s
queue is empty, then the next lower priority queue’s frames egress, etc. This ap-
proach can cause the lower priorities to be starved out preventing them from
transmitting any frames but also ensures that all high priority frames egress the
switch as soon as possible.
In the weighted scheme an 8, 4, 2, 1 weighting is applied to the four priorities unless
an alternate weighting is programmed into the QoS Weights Table. This approach
prevents the lower priority frames from being starved out with only a slight delay
to the higher priority frames.

Some applications may require the top priority queue, or the top two priority queues
to be in a fixed priority mode while the lower queues work in the weighted approach.

Count mode Egress rate limiting count mode. This parameter is used to control which bytes in
the transmitted frames are counted for egress rate limiting as follows:
The egress rate limiting is done based on frame count [fps] as
opposed to the byte count [kbps] of the packet.

considered tagged if the egress frame going out onto the wire is tagged.
Rate [kbps] /
[fps] Egress data rate shaping. When Rate = 0 egress rate limiting is disabled.
NOTE: The Count mode parameter is used to control which bytes in the trans-
mitted frames are counted for egress rate limiting.
If the egress shaping is controlled by frame rate, the desired frame rate can vary
from 7.6k to 1.488M frames per second. Valid values are between 7600 and
1488000.
If the egress shaping is controlled by bit rate, the desired rate can vary from 64
kbps to 1 Gbps in the following increments:
Desired rate between 64 kbps and 1 Mbps in increments of 64 kbps
Desired rate between 1 Mbps to 100 Mbps in increments of 1 Mbps
Desired rate between 100 Mbps to 1 Gbps in increments of 10 Mbps
Therefore, the valid values are:
64, 128, 192, 256, 320, 384,..., 960,
1000, 2000, 3000, 4000, ..., 100000,
110000, 120000, 130000, ..., 1000000
Frame overhead
[B] Egress Rate Frame Overhead adjustment.
This parameter is used to adjust the number of bytes that need to be added to a
frame’s IFG (inter frame gap) on a per frame basis. This is to compensate for a
protocol mismatch between the sending and the receiving stations. For example
if the receiving station were to add more encapsulations to the frame for the nodes
109© RACOM s.r.o. – RAy2 Microwave Link
Configuration
further down stream, this per frame adjustment would help reduce the congestion
in the receiving station.
This adjustment, if enabled, is added to the Egress Rate Control’s calculated
transmitted byte count meaning Egress Rate Control must be enabled for this
Frame Overhead adjustment to work.
Weight table The weighted round robin alternate weighting can be defined here. The sequence
of the output queue numbers (0,1, 2 or 3) defines the sequence of the output queue
frame egressing. This sequence can be up to 128 items long.

An indicative description of the function of each block:
Frame
An incoming frame contains the destination MAC address DA and the source address SA. The VLAN
802.1p priority can be contained in the Ethernet header and the DSCP priority in the IP header. If the
frame is a member of a VLAN, it carries it's VID number and 802.1q priority in the tag.
VLAN
A frame is received through ports Eth1, Eth2, Air or from microwave CPU. The head of the frame may
change at this time based on parameters set in the VLAN menu.
All untagged frames are assigned a VID. A tagged (VLAN) framework can have its own VID overwritten
by a default VID.
The packet priority can be ovewritten according to parameter menus QoS, VLAN and ATU.
The FID for searching in the ATU table is allocated to the frame within the VLAN menu (by the input
port) or from the corresponding VID in the VTU table.
Member parameter can limit the allowed output direction of ports.
Frames sent from a unit transfers through an output port. The Egress mode parameter bound to the
port either adds or removes the VLAN tag.
VTU
Values in the VID determine search results from the VTU table. These are created manually. The SID
index (enabled ports in terms of STP) FID index (for searching in the address table ATU) taken from
this search result are assigned to the frame. This FID will overwrite the FID from menu VLAN.
Based on this, the VTU can also overwrite the priority of this frame.
The permitted output ports and method of working with VLAN tag on the output are also defined here.
STU
The Spanning tree protocol in this table maintains the status of ports from the viewpoint of the authorized
network throughput and the learning of routing. Protocol MSTP is used.
Each VTU entry uses some of the entries in the STU. Entries in the ATU are created in accordance
with these assigned states.
The port state behaviour is determined by the STP.
ATU settings
Any assigned parameters dictate how the ATU table should be used.
The Global section of this menu provides for passage of MGMT frames (e.g. BPDU).
In the Port settings section, the behaviour of individual port is defined:
115© RACOM s.r.o. – RAy2 Microwave Link
Configuration
- Behaviour of the ATU table in terms of automatically creating records (Learning, Hold at 1, ATU refresh,
Learn limit).
- Discarding frames according to the source addresses.
- Handling frames with unfamiliar destination addresses.
- The frames' priority can be overridden by the SA or the DA.
ATU
The ATU table determines the output port on the RAy according to the DA in the frame.
Records are arranged according to the FID and the MAC addresses.
The table is created and maintained based on informations contained in incoming frames (learning).
Manual recording is also possible.
The record can be dynamic or static.
Priority frames with a static record can be overridden by the SA or DA.
The results of searching the ATU provide the set of output ports or trunk number.
RSTP
The RSTP demon turns off redundant paths through the network (switch ports), or re-activates them
in the case of failure in other branch.
The Global section of this menu contains switch priority for the RSTP and necessary time constants.
The Port settings section holds the value of each port as seen by the RSTP. This information indicates
if the RSTP shuts down or restarts a redundant port if a route is interrupted.
Trunk
The Trunk enables the distribution of data load on multiple ports. The ratio of distribution is determined
by parameter Balancing mode.

802.1q mode This parameter determines if 802.1q base VLANs are used along with port based
VLANs for this Ingress port. It also determines the action to be taken if an 802.1q
VLAN Violation is detected. VLAN barriers (both port based and 802.1q based) can
be bypassed by VLAN Tunnel.
Use Port Based VLANs only. The VID assigned to the frame is the

The ingressing frame is checked fully against the record in the VTU
table. The VID and the Member tag parameters are validated to allow
the frame to ingress.
secure
Discard
tagged When this parameter is enabled all non-MGMT frames that are processed as tagged
are discarded as they enter this switch port. Priority only tagged frames (with a VID
of 0x000) are considered untagged. This feature works whether 802.1q is enabled on
the port or not.
If the port is configured in Provide Mode and this parameter is enabled, frames that
contain an Ether Type that matches the port's PortEType (Ether type parameter) that
have a non-zero VID will be discarded.
Discard
untagged When this parameter is enabled all non-MGMT frames that are processed as untagged,
are discarded as they enter this switch port. Priority only tagged frames (with a VID
of 0x000) are considered untagged. This feature works whether 802.1q is enabled on
the port or not.
If the port is configured in Provide Mode and this parameter is enabled, frames that
don't contain an Ether Type that matches the port's PortEType (Ether type parameter)
that have a non-zero VID will be discarded.
VTU priority
override When this parameter is set to anything other than none, VTU priority overrides can
occur on this port. A VTU priority override occurs when the determined VID of a frame
results in a VID whose Use VID priority parameter is enabled. When this occurs three
(other than none) forms of priority overrides are possible:
Normal frame priority processing occurs.none
The VID priority value assigned to the frame's VID (in the VLAN
database) is used to overwrite the frame's previously determined
frame
FPri (frame priority). If the frame egresses tagged the priority in the
frame will be this new VID priority value - the frame is permanently
modified.
RAy2 Microwave Link – © RACOM s.r.o.120
Configuration
The VID priority value assigned to the frame's VID (in the VLAN
database) is used to overwrite the frame's previously determined
queue
QPri (queue priority). The QPri is used internally to map the frame
to one of the egress queues inside the switch. QPri override will not
affect the contents of the frame in any way.
Both the above overrides take place on the frame.frame+queue
The VTU Priority override has higher priority than the port's Default Priority and the
frame's IEEE and/or IP priorities. The priority determined by the frames' VID can
however be overridden by the frames' SA and/or DA Priority Overrides.
Force default
VID Force to use Default VID. When 802.1q is enabled on this port and this parameter is
enabled, all Ingress frames' VID are ignored and the Default VID is assigned and re-
placed into the frame (if the frame egresses tagged). When this parameter is disabled
all IEEE802.3ac Tagged frames with a non-zero VID use the frames' VID unmodified.
When 802.1q is disabled on this port, this bit has no effect.
Default VID Default VLAN Identifier. When 802.1q is enabled on this port the Default VID parameter
is used as the IEEE Tagged VID added to untagged or priority tagged frames during
egress that ingressed from this port. It is also used as a tagged frame's VID if the
frame's VID was 0x000 (i.e., it is a priority tagged frame) or if the port's Force Devault
VID is enabled.
When 802.1q is disabled on this port, the Default VID field is assigned to all frames
entering the port (whether tagged or untagged). This assignment is used internal to
the switch.
FID Port's Default Filtering Information Database (FID). This parameter can be used with
non-overlapping VLANs to keep each VLAN's MAC address mapping database sep-
arate from the other VLANs. This allows the same MAC address to appear multiple
times in the address database (at most one time per VLAN) with a different port
mapping per entry. This field is overriden by the FID returned from a VTU hit and it
should be zero if not used. It must be a unique number for each independent, non-
overlapping, address database if used.
IGMP
snooping IGMP and MLD Snooping. When this parameter is enabled and this port receives an
IPv4 IGMP frame or an IPv6 MLD frame, the frame is switched to the CPU port over-
riding the destination ports determined by the DA mapping. When this parameter is
disabled IGMP/MLD frames are not treated specially.
IGMP/MLD Snooping is intended to be used on Normal Network or Provider ports
only.
ARP
mirroring When this parameter is enabled non-filtered Tagged or Untagged Frames that ingress
this port that have the Broadcast Destination Address with an Ethertype of 0x0806
are mirrored to the CPUDest port. This mirroring takes place after the ingress mapping
decisions to allow ARPs to get to a CPU that is otherwise isolated. When this bit is
cleared to a zero no special ARP handling will occur.
VLAN tunnel When this parameter is disabled, the port based VLANs defined in the VLAN Table,
802.1q VLANs defined in the VTU and Trunk Masking are enforced fo ALL frames.
When this parameter is enabled, the port based VLAN Table masking, 802.1q VLAN
membership masking and the Trunk Masking are bypassed for any frame entering
this port with a DA that is currently 'static' in the ATU. This applies to unicast as well
as multicast frames.
121© RACOM s.r.o. – RAy2 Microwave Link
Configuration
While enabled, the Unicast frames with the management CPU DA can go from the
Eth1 and Eth2 ports in to the CPU port. The static record with the CPU DA in the ATU
table has to be configured (it is pre-configured by default).
Member
(VLAN Table) The In Chip Port based VLAN Table contains parameters used to restrict the output
ports to which an input port can send frames. These parameters (VLANTable bits)
are used for all frames, except for MGMT frames, even if 802.1q is enabled on this
port. These parameters restrict where a port can send frames to (unless a VLANTunnel
frame is being received). If ForceMap (Learning) is enabled, these parameters indicate
which port or ports all frames that ingress this port are sent to overriding the mapping
from the address database.
The default setting prevents sending frames from Eth1 to Eth2 and vice versa. This
is very important for separating different networks (e.g. different customers) connected
to separate user ports.
The Link authorization guard affects the user data flow through the Air channel. When
the Link authorization guard is enabled, the user Ethernet ports to Air port connection
control is disabled. Parameter status of user Ethernet to Air port connection changes
dynamically according to Link authorization status.

(ForceMap) When this parameter is disabled, normal frame processing occurs.
When this parameter is enabled, all received frames will be considered MGMT (MG-
MT=Management frames, frames that can tunnel through Blocked ports) and are
mapped to the port or ports defined in the VLANTable bits overriding the mapping
from the address database. The forcing function is needed to get BPDU frames to
egress specific ports by the CPU for the Spanning Tree Protocol. ForceMapped frames
will egress ports that are not in the Disabled port state (i.e., they are MGMT frames
and will egress via Blocked ports). This parameter is accessible by the CPU's Ingress
Header so the CPU can enable and disable MGMT and forcing on a frame by frame
bases.
NOTE: Learning is disabled on MGMT frames, so enabling this parameter also
disables learning on frames entering this port.
Hold at 1 Hold Aging ATU Entries at an Entry State value of 1. When this parameter is disabled,
a zero normal Aging occurs for ATU entries associated with this port. When this

source port for that MAC address). This mode is a form of MAC based
802.1X where some frames can be forced to the CPU for further
authentication prior to full authorization.
Learn limit
(LearnLimit) When this parameter is set to zero, normal address learning and frame policy occurs.
When this parameter is non-zero the number of MAC addresses that can be learned
on this port are limited to the value of this parameter. Automatic learning and frame
policy will occur normally until the number of unicast MAC addresses auto-learned
from this port reaches the port's LearnLimit (addresses that were learned from this
port but were aged out are not counted - i.e., this register limits the number of 'active'
unicast MAC addresses associated to this port). When the LearnLimit has been reached
any frame that ingresses this port with a source MAC address not already in the ad-
dress database that is associated with this port will be discarded (the port will act as
if the port is Locked and the port's DropOnLock SAFiltering mode is set). Normal auto-
learning will resume on the port as soon as the number of 'active' unicast MAC ad-
dresses associated to this port is less than the LearnLimit (due to address aging).

SA priority
override When any other than "none" mode is selected, SA ATU priority overrides can occur
on this port. An SA ATU priority override occurs when the source address of a frame
results in an ATU hit where the SA's MAC address returns an EntryState that indicates
Priority Override. When this happens three forms of priority overrides are possible
(other than none):
Normal frame priority processing is active.none
PRI value assigned to the frame's SA (the MAC priority field in the
ATU database) is used to overwrite the frame's previously determined
frame
frame priority (FPri). If the frame egresses, the tagged priority in the
frame will be this new PRI value.
The two upper bits of the PRI value assigned to the frame's SA (the
MAC priority field in the ATU database) are used to overwrite the
queue
frame's previously determined queue priority (QPri). The QPri is used
internally to map the frame to one of the egress queues inside the
switch. QPri override will not affect the contents of the frame in any
way.
Both above overrides take effect on the frameframe+queue
The SA ATU Priority Override has a higher priority than the port's Default Priority, the
frame's IEEE and/or IP priorities and the VTU Priority Override. The priority determined
by the frame's SA can however be overridden, by the frame's DA Priority Override.
DA priority
override When any other than none mode is selected, the DA ATU priority overrides can occur
on this port. A DA ATU priority override occurs when the source address of a frame
results in an ATU hit where the DA's MAC address returns an EntryState that indicates
Priority Override. When this occurs three forms of priority overrides are possible
(other than none):
Normal frame priority processing is active.none
PRI value assigned to the frame's DA (the MAC priority field in the
ATU database) is used to overwrite the frame's previously determined
frame
frame priority (FPri). If the frame egresses the tagged priority in the
frame will be the new PRI value.
The two upper bits of the PRI value assigned to the frame's DA (the
MAC priority field in the ATU database) are used to overwrite the
queue
frame's previously determined queue priority (QPri). The QPri is used
internally to map the frame to one of the egress queues inside the
switch. QPri override will not affect the contents of the frame in any
way.
Both of the above overrides take place on the frameframe+queue
The DA ATU Priority Override has the highest priority over the port's Default Priority,
the frame's IEEE and/or IP priorities, the VTU Priority Override and the SA Priority
Override.

this parameter is used to set the desired address database number that is to be asso-
ciated with this ATU Entry's MAC Address. When frames ingress the switch, the VID
assigned to the frame is used to access the VTU. The VTU returns the FID associated
with that VID for MAC address lookups in to the ATU.

Ingress
monitor
source
When this parameter is enabled, any frame that ingresses this port is also sent to the
Ingress monitor destination port. The frame is sent to this port even if it is discarded
due to switching policy but the frame will not be forwarded if it contains an error (such
as CRC, etc.) or is filtered by ingress rate limiting.
Egress
monitor
source
When this parameter is enabled any frame that egresses this port will also be sent to
the Egress monitor destination port. The 802.1q mode and VTU entries on the Egress
monitor destination port must be set to be the same as they are on the Egress monitor
source port so the frames egress with the same tagged or untagged information.
Mirror
destination Frames that ingress a port that trigger a policy mirror are mapped (copied) to this port
as long as the frame is not filtered or discarded.
CPU
destination CPU destination port can not be changed. It is shown here to better understand the
description of some other parameters which interact with the CPU destination port.
For example the trap value of the Policy* parameters cause frames to be forwarded
to this CPU destination port.
Policy There are four different operations as a result of a policy:
Normal frame switching.normal
Mirror (copy) frame to the Mirror destination port.

RSTP
Fig. 7.41: Menu Switch settings - Advanced - RSTP
The Rapid Spanning Tree Protocol (RSTP) is a network protocol that ensures a loop-free topology for
any bridged Ethernet local area network. The basic function of RSTP is to prevent bridge loops and
the broadcast radiation that results from them. Spanning Tree Protocol also allows network design to
include spare (redundant) links to provide automatic backup paths if an active link fails, without the
danger of bridge loops, or the need for manual enabling/disabling of these backup links.
RSTP enable When RSTP is enabled, the bridge is created and RSTP service is initiated. Should
the RAy2 unit be connected via two Etherent cables (using Eth1 and Eth2 ports), the
active participation of the RSTP protocol may be necessary. If the parameter is not
enabled, the RAy2 unit transfers the BPDU frames transparently.
NOTE: To enable proper RSTP functionality, these switch parameters has to be set:
Switch settings / Interface / Port advanced / Frame mode / p5 CPU: "ether type
DSA"
Switch settings / Interface / Port advanced / Ether type / p5 CPU: "0xDADA"
Switch settings / Advanced / ATU settings / Reserved multicast to CPU: "Enable"
Bridge
priority The priority value is a number between 0 and 61440 in incremental steps of 4096,
with a default value of 32768. Lower priority values are 'better'. The bridge with the
lowest priority value will be elected 'root bridge'.
Hello time [s] The hello time is the time between each Bridge Protocol Data Unit (BPDU) that is sent
on a port. Hello time is equal to 2 seconds by default.
RAy2 Microwave Link – © RACOM s.r.o.138
Configuration
Max age [s] The max age timer controls the maximum length of time that passes before a bridge
port saves its configuration BPDU information. This time is set to 20 sec by default.
Forward
delay [s] The forward delay is the time that is spent in the listening and learning state. This time
is equal to 15 sec by default.
Algorithm This parameter sets the bridge's spanning tree algorithm to operate in normal (RSTP)
or force it to operate in slow (STP) mode. In normal mode, RSTP reverts back to STP
on ports where it sees other hosts operating in STP mode.
Port name Identification of the internal switch port. The switch ports are connected to an external
port or to an internal device (radio modem, management CPU).
The external port (with RJ45 interface) labeled "ETH1+POE". Port 2.
The external port (with SFP interface) labeled "ETH2". Port 4.

Port priority The ports' priority value is a number between 0 and 240 in increments of 16, with a
default value of 128.
Path cost The Path cost can be set automatically or manually. Entering the value of zero sets
this parameter automatically. The automatic setup is based on link speed.
Edge Selecting the checkbox sets the port as an "edge" port. If a port is an edge port it is
assumed to be a leaf link in the graph, not connected to any other bridges. Receiving
any STP BPDU's on a port configured as an edge port temporarily overrides edge
port behaviour for the port.
MAC address The ports' default MAC addresses are the same as the MAC address of the RAy2
unit.

Trunk
Fig. 7.42: Menu Switch settings - Advanced - Trunk
Port trunking is supported by the device using any combinations of ports. The ports that are to be as-
sociated with the trunk need to have all the port members' defined with the same Trunk Id and the
Enabled parameter has to be enabled.
When a frame enters a Trunk Port its Source Address (SA) is learned with its association to the ingress
port's TrunkID number. In this way the contents of the address database contain the same association
with the frame's SA regardless of the link of the trunk the frame entered the switch.
When frames are routed back toward a trunk the frame will have its Destination Address (DA) found
from the address database. If the frame's DA is unknown the frame will try to flood out all ports of the
trunk (this is OK in so far as this will be fixed with load balancing). If the frame's DA is found, the entry
will indicate mapping to a trunk and the entry's DPV bits will contain the TrunkID associated with this
frame's DA. This TrunkID needs to be converted into a DPV (Destination Port Vector) that the rest of
the switch can use. This is accomplished by accessing the Trunk Mapping table using the TrunkID that
was in the ATU's entry.
Balancing
mode Hash DA and SA for TrunkMask selection. Trunk load balancing is accomplished using
the frame's DA and SA fields to access one of eight Trunk Masks. Two options are
available:
The lower 3 bits if the frame's DA and SA are XOR'ed together to
select the TrunkMask to use.

8. Command Line Interface
The Command Line Interface (CLI) provides an alternative to HTTPS access. CLI allows you to work
in a text regime interface using an ssh (putty) or telnet client.
8.1. Connection via CLI
8.1.1. Telnet
Use the telnet client to connect to the unit with service IP address 192.168.169.169. Type this in the
command prompt:
telnet 192.168.169.169
Then use the username and password from the menu Service access/Users for https access
(by default admin, admin). This works if Service access/Services/Telnet is checked in
https access.
8.1.2. Putty
Connection using putty client. Type this into the Host Name (or IP address) field:
admin@192.168.169.169
Click Open. Then enter the password admin. This procedure (without key) is subject to selection
Service access/Services/SSH on in https access.
If you own the private key part, then you do not need a password. In putty, continue by selecting
Connection/SSH/Auth and selecting path to file with key e.g. key.ppk. Use Session/Logging
to save the putty configuration. To access the unit via CLI simply select the connection in putty and
click Open.
8.1.3. SSH
Connection using client ssh in Linux.
ssh admin@192.168.169.169 -i key
If you know the password and it is enabled in Service access/Services/SSH onlykey in https
access, you can skip the key and use password in the next query.

8.3. Configuration with CLI
8.3.1. Configuration file
• Configuration backup
cli_cnf_backup_get
Saves the configuration of both units to file cnf_backup.tgz into the working directory.
• Configuration restore
cli_cnf_set -t b -b cnf_backup.tgz
Restores configuration of both units from file cnf_backup.tgz
• Default configuration list
cli_cnf_def_show
Warning, the command
cli_cnf_factory_set
is not a default setting - it uses factory settings, deleting all logs and saved data. It is very likely that
the connection to peer unit will be interrupted!
8.3.2. Firmware upgrade
• Current version of fw
cli_info_station
• Preparation of files
fw package, for example bm4-RACOM-0.1.12.0.cpio copy using ssh or putty into folder /tmp
in RAy17
Command
cli_fw_clear_buffer
Clears the RAy2 buffer
cli_fw_buffer_status
Checks buffer status
• Saving into buffers
cli_fw_load_package -f /tmp/bm4-RACOM-0.1.12.0.cpio
A new fw package is loaded into the buffer (20 sec)
cli_fw_upload2peer
The fw package is also loaded into the peer unit (20 sec)
• Upgrade
cli_fw_upgrade -t b
Firmware in both units will be replaced with new version from the buffer. After 3 minutes, this message
appears:
Firmware upgrade started. Estimated time to finish is 370 s.
Connection is terminated. After a few minutes, log in to RAy2 again
8.3.3. Remote unit authorization
The RAy2 unit in default configuration, establishes a connection with any remote unit and both units
act as a communication pair. Should the higher protection from the unauthorized communication take-
over be required, it is possible to use the so called Secured mode of remote unit authorization. This
mode is based on locking the two specific units into one communication pair. Units with Secured mode
RAy2 Microwave Link – © RACOM s.r.o.168
Command Line Interface
activated refuse to make a connection with any other communication unit. The units are locked using
the unique authorization keys. The keys are exchanged between the units concerned. The authorization
keys can be backed up to an external medium to be able to make a service unit exchange, if necessary.
Should The Link authorization quard be disabled, the user data occurs even it the remote unit is not
authorized.
The Secured mode set up process consists of a few steps:
• Unique authorization keys generation:
cli_link_key_gen -t b
• Authorization keys exchange between the two communication units:
cli_link_key_swap
• Authorization keys activation:
cli_link_key_apply -t b
Parameter -t determines whether we configure the whole link (-t b) or only one unit (-t l).
• Secured mode activation. Both sides of the link must have identically secured mode set On or Off:
cli_cnf_set -t b SVC_SECURE_PEER_MODE=on PEER_SVC_SECURE_PEER_MODE=on
• Secured mode de-activation:
cli_cnf_set -t b SVC_SECURE_PEER_MODE=off PEER_SVC_SECURE_PEER_MODE=off
• Backup of the keys to an external medium. The backup has to be performed to be able to make
service exchange of the corrupted unit, if necessary. The new exchanged unit is not able to make
an active connection with the other unit if it is not loaded with the proper authorization key.
cli_link_key_save -s s -f <file>
The key is backed up to a selected file in the internal unit file system. It can be transferred to an
external medium using for example the scp client.
• Authorization key restoration from the external medium.
The key has to be transferred to the unit internal file system first. The scp client can be used. The
CLI commands can be applied subsequently:
cli_link_key_load -t b -f <file>
cli_link_key_apply -t b

9. Troubleshooting
•Polarization incorrect
Install the unit with the correct horizontal or vertical polarization: The arrow mark (placed just next
to the Status LED) indicates the unit RX polarization. When the arrow is perpendicular to the earth,
the unit receives a signal in vertical polarization. When the arrow is parallel to the earth, the unit
receives a signal in horizontal polarization. The connectors must point downward at an angle.
•The link cannot be established
Start with the most “resilient” configuration. This configuration depends on the type of unit. We re-
commend using the narrowest available bandwidth (e.g. 3.5 MHz), the lowest modulation level
(QPSK) and maximum available output power. TX and RX channels must be the same as the RX
and TX channels in the remote unit. When the connection has been established and the antennas
have been directed, proceed with operation parameters.
Units operating in licensed bands (RAy2-10, RAy2-11) are mounted with the same RX polarization
(the polarization indication arrows show the same polarization on both units).
Units working in the bands equipped with RAy2-17 and RAy2-24 units must be mounted with opposite
polarization; one with RX horizontal polarization (horizontal arrow) and the second with RX vertical
polarization (vertical arrow).
•Access to the Local unit is blocked
Access to the Local unit may be accidentally blocked, for instance by disabling HTTPS access. If
you can access the Remote unit over HTTPS, type its address in your web browser's address field.
The link will transfer the packet over the Local unit with blocked service access all the way to the
Remote unit, which will give you access to the control menus of both units. Warning, the Remote
unit will report as Local.
•Distinguishing Local-Remote
A unit accessed via service access always reports as Local. If you connect through another (peer)
unit and radio channel, a certain amount of caution is necessary. For example, do not reduce the
transmission power so that the link interrupts accidentally. Errors of this type should be fixed by the
rollback function within approx. 1 minute.
Resolution can be done by comparing the length of ping on Local and Remote. Pinging the unit
behind the radio channel is slower. The difference is more pronounced in the case of a long packet
and the low speed of the radio channel.
•Access security
For better protection against unauthorised access to configuration you should only allow as few
kinds of access as possible. The most secure type is SSH with key – leave only SSH active with
"only key" choice.
•RSS
To configure the link and monitor its state, several menus display the RSS signal strength. Please
keep in mind, that Ray2 is not a measuring instrument, hence the precision of the RSS reading is
RAy2 Microwave Link – © RACOM s.r.o.170
Troubleshooting
limited. Though, in most situations the RSS reading accuracy is better than ± 2dB, the absolute
RSS value should not be used for accurate comparisons e.g. between two links.
•Problem with https certificate
See the Appendix G, Https certificate
•Overexcited receiver
A natural property of each radio receiver is to compress the signal in one of the functional blocks,
typically in a second receiving mixer. A downside of this property is the distortion of the input signal
(decrease in the signal to noise ratio, i.e. the distortion measured as SNR).
In extreme cases, this can lead to the disintegration of the radio link due to reduced signal to noise
ratio (distortion). Extreme limits for guaranteed availability of the RAy2 connections are:
○ -30 dB for all channel bandwidths and fixed modulation 256QAM
○ -10 dB for all channel bandwidths and fixed modulation QPSK

(see Configuration, item “Bandwith [MHz]”. In addition to the bandwith definition, the name may
contain additional text which defines the respective alternative of channel plan. Examples:
• “Bandwith: 40 MHz (ITU)” means that the nominal frequencies in the table follow the recom-
mendation ITU-R F.387 rec.1.2. for 40 MHz bandwith, see also the note 5) below.
•“Bandwith: 40 MHz (ACMA)” means that the table describes the 40 MHz channel plan defined
by ITU-R F.387 rec. 1.1. (b), applied e.g. in Australia.
3) The complete frequency range (approx.)
4) Duplex spacing – the frequency difference between the Upper and Lower channels in a duplex
pair.
Optional: The minimum and the maximal duplex spacing used in the table of frequencies.
5) The name of standard or recommendation defining the respective channel plan.
6) Name of the sub-band defined by channels in the table.
7) Name of the “Frequency table” containing the channel set described (see Configuration, item
"Frequency tables").
8) The channel number according to RAy unit configuration interface (see Configuration, item “TX
channel [GHz]”).
9) The nominal TX frequency of the Lower-band channel
10) The nominal TX frequency of the Upper-band channel.
11) Table version.

11.3. Professional installation
RAy2 units are only intended for installation by professionally trained people and in locations not ac-
cessible to the public. Installation and servicing must be carried out by personnel with appropriate
technical training and knowledge of potential hazards.
RAy2 units shall be installed according to local Electrical Safety Codes.
It is the responsibility of the installer to ensure that all building and safety codes are met and that the
installation is fully completed and equipment properly secured.
11.4. RoHS and WEEE compliance
The RAy2 is fully compliant with the European Commission‟s RoHS (Restriction of Certain Hazardous
Substances in Electrical and Electronic Equipment) and WEEE (Waste Electrical and Electronic
Equipment) environmental directives.
Restriction of hazardous substances (RoHS)
The RoHS Directive prohibits the sale in the European Union of electronic equipment containing these
hazardous substances: lead, cadmium, mercury, hexavalent chromium, polybrominated biphenyls
(PBBs), and polybrominated diphenyl ethers (PBDEs).
End-of-life recycling programme (WEEE)
The WEEE Directive is concerned with the recovery, reuse, and recycling of electronic
and electrical equipment. Under the Directive, used equipment must be marked, collected
separately, and disposed of properly. Racom has instigated a programme to manage
the reuse, recycling, and recovery of waste in an environmentally safe manner using
processes that comply with the WEEE Directive (EU Waste Electrical and Electronic
Equipment 2002/96/EC).
Battery Disposal —This product may contain a battery. Batteries must be disposed of properly, and
may not be disposed of as unsorted municipal waste within the European Union. See the product
documentation for specific battery information. Batteries are marked with a symbol, which may include

Appendix F. SSH key generation
Linux
Use “ssh-keygen” command.
Windows
Use "PUTTYGEN.EXE" software, which is typically located in the c:\Program Files\putty\ directory and
apply the "Generate" button.
To use CLI (Command Line Interface) access the unit with a PuTTY client. Access is protected by a
key. The key can be in Linux format and it begins:
-----BEGIN DSA PRIVATE KEY-----
.....
or in PuTTY format which begins:
PuTTY-User-Key-File-2: ssh-dss
.....
To convert the Linux format to PuTTY do the following:
In c:\Program Files\putty\ directory run PUTTYGEN.EXE
Click on “Load” and choose the Linux private key.
In the next window type your password into the Key passphrase and Confirm passphrase fields. After
that click Save private key. Choose location and save the key.

SSH key generation
Appendix G. Https certificate
When switching from older versions of the firmware the access certificate for https is changed. New
web browser configuration must take place in order to remove the link between the microwave link
management IP address and the previous https certificate.
Mozilla Firefox how-to:
1. https certificate
Remove management IP address from the list: Tools - Options - Advanced - Encryption
- View Certificates – Servers
Another possibility: remove certificate Racom “RAy” or Racom “RACOM's product” from the list:
Tools - Options - Advanced - Encryption - View Certificates – Authorities
2. Upon the new RAy unit connection following message appear: “This Connection is Untrusted”.
3. If you are sure that there is no security risk, choose: “I Understand the Risks”.
4. The next step is “Add Exception...”
5. Finally, you have to “Confirm Security Exception”. If the Apply button is not active, it is necessary
to perform step No. 1/ and restart web browser.
Internet Explorer may give following message “There is a problem with this website's security certificate”.
Choose “Continue to this website (not recommended)”. The address line gives you status information
“Certificate Error”. This inconvenience is caused by impossibility to create security certificate valid for
list of user selected IP addresses.
