Preparing for configuration and alignment
This section describes the checks to be performed before proceeding with unit configuration and
antenna alignment.
Safety precautions
All national and local safety standards must be followed while configuring the units and aligning
the antennas.
Warning
Ensure that personnel are not exposed to unsafe levels of RF energy. The units start to
radiate RF energy as soon as they are powered up. Respect the safety standards
defined in Compliance with safety standards on page 4-22, in particular the minimum
separation distances.
Observe the following guidelines:
•
Never work in front of the antenna when the ODU is powered.
•
Always power down the PSU before connecting or disconnecting the drop cable
from the PSU, ODU or LPU.
Regulatory compliance
All applicable radio regulations must be followed while configuring the units and aligning the
antennas. For more information, refer to Compliance with radio regulations on page 4-27.
Caution
If the system designer has provided a list of channels to be barred for TDWR radar
avoidance, the affected channels must be barred before the units are allowed to
radiate on site, otherwise the regulations will be infringed. To bar these channels,
follow the procedure Barring channels on page 7-39.
Attention
Si le concepteur du système a fourni une liste de canaux à interdire pour éviter les
radars TDWR, les cannaux concernées doivent être interdits avant que les unités sont
autorisées à émettre sur le site, sinon la réglementation peut être enfreinte. Pour
bloquer ces canaux, suivez la procédure Barring channels page 7-39.

Preparing for configuration and alignment
Selecting configuration options
Use the installation report to determine which configuration options are required. Refer to PTP
LINKPlanner on page 3-25.
Generating license keys
To obtain License Keys for capabilities that are not factory-installed, proceed as follows:
Identify and purchase access keys for the required capability upgrades by referring to ODU
capability upgrades on page 2-9.
Obtain the MAC Address of the ODU (it is on the System Status page).
Go to the Cambium Support web page (see Contacting Cambium Networks on page 1) and
navigate to the Cambium Networks License Key Generator.
Enter the MAC Address and Access Key.
If the ODU is to operate in a regulatory band that is not factory-installed, select the required
regulatory band from the list. The contents of this list depend upon ODU regional variant.
Select any other required capabilities from those that are available.
Submit the web form. Cambium will send the License Key by email.
Use the Software License Key page to configure the ODU with newlicense keys (Software License
Key page on page 6-11).

169.254.1.1. A good example is 169.254.1.3:
Enter a subnet mask of 255.255.0.0. Leave the default gateway blank.
Connecting to the PC and powering up
Use this procedure to connect a management PC and power up the PTP 650.
Procedure:
Check that the ODU and PSU are correctly connected.
Connect the PC Ethernet port to the LAN port of the PSU using a standard (not crossed)
Ethernet cable.
Apply mains or battery power to the PSU. The green Power LED should illuminate
continuously.
After about 45 seconds, check that the orange Ethernet LED starts with 10 slow flashes.
Check that the Ethernet LED then illuminates continuously. If the Power and Ethernet LEDs
do not illuminate correctly, refer to Testing link end hardware on page 8-2.

Configuring the ODU ports for customer and management traffic
Use this procedure to achieve a correct combination of settings of the Port Allocation attributes
(Main PSU, Aux and SFP). The valid port allocation combinations are summarized in Table 118.
In the course of this procedure, the system will display one or more error messages that start with
“Please check your port allocations“ and end with one of the following:
•
“there must be exactly one port configured to pass data”
•
“there are no ports configured for management”
•
“you cannot configure both In-Band and Out-of-Band Remote Management”
•
“there are too many ports configured for Out-of-Band Remote Management”
When this happens, click OK and continue. If the procedure is followed correctly, no error message
will be displayed on completion.
To allocate the ODU ports to customer and management traffic, proceed as follows:
Set all enabled ports (Main PSU, Aux and SFP) to Disabled and click OK in response to the
error message.
Choose exactly one port to carry customer data, subject to the following restrictions:
•
If TDM is not available or the TDM Interface attribute is set to None, choose any one of the
enabled ports to carry customer data (Main PSU, Aux or SFP).
•
If the TDM Interface attribute is set to either E1 or T1, choose only the Main PSU port to
carry customer data.
For In-Band management, set the chosen customer data port to Date and In-Band
Management, otherwise set it to Data Only.
For Out-of-Band Local management, set one or both of the remaining ports (Main PSU, Aux or
SFP) to Out-of-Band Local Management.
This setting is compatible with a customer data port setting of either Date and In-Band
Management or Data Only.
For Out-of-Band Remote management, set exactly one of the remaining ports (Main PSU, Aux
or SFP) to Out-of-Band Remote Management, subject to the following restrictions:
•
If the customer data port is set to Date and In-Band Management, do not set any port to
Out-of-Band Remote Management.
•
Do not set more than one port to Out-of-Band Remote Management.
Check that at least one port has been set to either Date and In-Band Management or Out-ofBand Local Management or Out-of-Band Remote Management (subject to the restrictions
described in the above steps). If this is not the case, then review and correct the allocations.

Wireless Configuration.
Caution
The lower center frequency attribute must be configured to the same value for both
the Master and Slave, otherwise the wireless link will fail to establish. The only way to
recover from this situation is to modify the Lower Center Frequency attributes so that
they are identical on both the master and slave units.
Note
When configuring a linked pair of units, use the Master Slave Mode to ensure that
one unit is Master and the other is Slave.
Table 119 Wireless Configuration attributes
Attribute
Meaning
Master Slave Mode
Master: The unit controls the point-to-point link and its maintenance. On
startup, the Master transmits until a link with the Slave is made.
Slave: The unit listens for its peer and only transmits when the peer has
been identified.
Access Method
ODUs must be configured in pairs before a link can be established. Access
Method determines how paired ODUs will recognize each other.
Link Access: Each ODU must be configured with Target MAC Address
equal to the MAC Address of the other unit.
Link Name Access: Both ODUs must be configured with the same Link
Name.
Group Access: Only displayed when a Group Access license key has been
generated (Generating license keys on page 6-3) and submitted (Software
License Key page on page 6-11). Both ODUs must be configured with the
same Group ID attributes.
Target MAC Address
Only displayed when Access Method is set to Link Access. This is the
MAC Address of the peer unit that will be at the other end of the wireless
link. This is used by the system to ensure the unit establishes a wireless
link to the correct peer. The MAC Address can be found embedded within
the serial number of the unit. The last six characters of the serial number
are the last three bytes of the unit’s MAC address.
UNDER DEVELOPMENT

Attribute
Meaning
Link Name
Only displayed when Access Method is set to Link Name Access.
Link Name may consist of letters (A-Z and a-z), numbers (0-9), spaces, and
the following special characters: (),-.,:<=>[]_{}
Link Name must be same at both ends and different to site name.
Group Id
Only displayed when Access Method is set to Group Access. A link can
only be established between units that have identical Group IDs.
Dual Payload
Disabled: The link maximizes robustness against fading and interference.
Enabled: The link attempts to reach maximum throughput at the expense
of robustness against fading and interference.
Max Receive
Modulation Mode
The maximum mode the unit will use as its adaptive modulation. By
default the Max Receive Modulation Mode is the highest mode available.
For minimum error rates, set the maximum modulation mode to the
minimum necessary to carry the required traffic.
Lowest Data
Modulation Mode
The lowest modulation mode that must be achieved before the link is
allowed to bridge customer data Ethernet frames. This does not affect the
bridging of management data: if out-of-band remote management is
enabled, this will continue regardless of modulation mode.
Link Mode
Optimization
IP Traffic: The link is optimized for IP traffic to provide the maximum
possible link capacity.
TDM Traffic: The link is optimized for TDM traffic to provide the lowest
possible latency. This is the only available setting when TDM is enabled
(Interface Configuration page on page 6-14).
TDD
Synchronization
Mode
Disabled: The link does not employ TDD synchronization.
Enabled: The link employs TDD synchronization. This is configured in the
Installation Wizard; see TDD synchronization page (optional) on page 628. For a basic description, see TDD synchronization on page 1-19.
When TDD Synchronization Mode is set to Enabled, the following
restrictions apply: Ranging Mode and Target Range are disabled, and Link
Symmetry is limited to 1 to 1.
Regulatory Band
The regulatory band selected from the list in the license key.
Channel Bandwidth
Bandwidth of the transmit and receive radio channels.

Attribute
Meaning
Link Symmetry
Only displayed when Master Slave Mode is set to Master.
Adaptive: Allows link symmetry to vary dynamically in response to
offered traffic load. This is not supported in the following cases:
•
Where radar avoidance is mandated in the region.
•
Link Mode Optimization is set to TDM Traffic.
“2 to 1”, “1 to 1” or “1 to 2”: There is a fixed division between transmit
and receive time in the TDD frame of the master ODU. The first number in
the ratio represents the time allowed for the transmit direction and the
second number represents the time allowed for the receive direction. The
appropriate matching Link Symmetry is set at the slave ODU
automatically. For example, if Link Symmetry is set to “2 to 1” at the
master ODU, then the slave ODU will be set automatically as “1 to 2”. In
this example, the master-slave direction has double the capacity of the
slave-master direction.
When TDM is enabled (Interface Configuration page on page 6-14), Link
Symmetry is limited to “1 to 1”.

Tx Color Code, Rx
Color Code
Tx Color Code and Rx Color Code may be used to minimize interference
in a dense network of synchronized PTP 650 units where some of the
units are operating on the same frequency. When this type of network is
designed, the Color Code values are normally specified in the link
planning report. In all other cases, Cambium Networks recommend that
Tx Color Code and Rx Color Code are left at the default value of A.
The value of Tx Color Code MUST always match the value of Rx Color
Code at the other end of the link.
Antenna Gain
Only displayed when the ODU is connectorized.
Gain of the remote antenna.
Cable Loss
Only displayed when the ODU is connectorized.
Loss in the ODU-antenna RF cable. If there is a significant difference in
length of the RF cables for the two antenna ports, then the average value
should be entered.
Maximum Transmit
Power
The maximum power (dBm) at which the unit will transmit, configurable
in steps of 1 dB. Its maximum value is controlled by the selected
combination of Regulatory Band, Bandwidth and (for connectorized units)
Antenna Gain and Cable Loss.
To prepare for antenna alignment, set this attribute to the alignment value
specified in the installation report (PTP LINKPlanner).
To prepare for link operation, set this attribute to the operational value
specified in the installation report (PTP LINKPlanner). This may be higher
than the alignment value.
Installation Mode

Auto..: During alignment, the wireless units use algorithms to calculate
link range. To implement automatic ranging, select a value that
corresponds to the estimated maximum range of the link:
Auto 0 to 40 km (0 to 25 miles).
Auto 0 to 100km (0 to 62 miles).
Auto 0 to 200km (0 to 125 miles).
Target Range: During alignment, the wireless units use the approximate
link distance (entered in Target Range) to calculate link range. The main
advantage of Target Range mode is that it reduces the time taken by the
units to range.
If preferred, range functions can be configured to operate in miles, as
described in Webpage Properties page on page 6-64.
Target Range
Only available when Ranging Mode is set to Target Range.
The approximate distance between the two wireless units to within

Caution
Auto-negotiation and forced Ethernet configuration:
•
To operate an Ethernet link at a fixed speed, set Auto Negotiation to Enabled and
limit Auto Neg Advertisement to the desired speed. If constrained auto-negotiation
fails, set Auto Negotiation to Disabled (forced Ethernet configuration) as a last
resort.
•
Both ends of an Ethernet link must be configured identically, because forced and
auto-negotiation are not compatible: a mixed configuration will cause a duplex
mismatch, resulting in greatly reduced data capacity.
•
The Auto Neg Advertisement or Forced Configuration data rates must be within the
capability of the Ethernet link partner, otherwise loss of service will occur.
Note
When TDM is enabled (Interface Configuration page on page 6-14), the following
restrictions are automatically applied:
•
Main PSU Port Auto Negotiation is set to Enabled.
•

Aligning antennas
Aligning antennas
This section describes how to align the antennas in a PTP 650 link, use the web interface to assist
with alignment, and check wireless performance after alignment.
Before performing this task, check that hardware installation is complete (apart from the network
connections) at both the Master and Slave sites.
Starting up the units
Use this procedure to connect one of the units to a management PC and start up both units.
Procedure:
Select the unit from which this process is to be controlled; either Master or Slave. This is the
“local” unit.
Check that the management PC is connected to the local unit, powered up and logged on as
described in Connecting to the unit on page 6-4.
Power up the remote unit.
Log into the local unit as described in Logging into the web interface on page 6-6.
Checking that the units are armed
Use this procedure to confirm that the units are in the armed state, ready for alignment.
In the armed state, the modulation mode is fixed at BPSK 0.63 Single, the TDD frame duration is
extended to allow the link to acquire at unknown range, and the transmit power is automatically
adjusted for optimum operation.
Procedure:
•
Select menu option Home. The System Summary page is displayed.
•
Check that the Install Arm State is set to Armed.
•
If the units are not armed, execute the installation wizard as described in Installation menu on
page 6-9.
UNDER DEVELOPMENT
Page 6-102
Chapter 6: Configuration and alignment
Aligning antennas
Aligning antennas
Use this procedure to align linked antennas (master and slave), whether integrated or
connectorized. The goal of antenna alignment is to find the center of the main beam. This is done
by adjusting the antennas while monitoring the receive signal level.
Preparation:
Ensure that the following parameters are available:
•
Location of both sites (latitude and longitude).
•
Bearing to the other end of the link for both sites.
•
Prediction of receive signal level for both ends of the link.
•
Prediction of link loss.
PTP LINKPlanner provides all of these parameters in the form of an installation report.
If a connectorized ODU is installed at either site with two separate antennas for spatial diversity,
refer to Aligning separate antennas for spatial diversity on page 6-104 before starting alignment.
Note
For improved radio performance, mount the integrated ODU at 45 degrees to the
vertical; this ensures that side-lobe levels are minimized for interference transmitted or
received at zero elevation.
To achieve best results, make small incremental changes to elevation and azimuth.
Caution
The action of tightening the mounting bolts can alter antenna alignment. This can be
helpful when fine-tuning alignment, but it can also lead to misalignment. To prevent
misalignment, continue to monitor receive signal level during final tightening of the
bolts.
Procedure:
At each end of the link, adjust the antenna to point at the other end of the link. This should be
done with the aid of a compass.
Without moving the master antenna, adjust the elevation and azimuth of the slave antenna to
achieve the highest receive signal level using one of the following methods:
•
ODU installation tones on page 6-105
•
Graphical Install page on page 6-107
Without moving the Slave antenna, adjust the elevation and azimuth of the Master antenna to
achieve the highest receive signal level (using one of the above methods).
Repeat steps 2 and 3 as necessary to fine-tune the alignment to find the center of the beam.
UNDER DEVELOPMENT
Page 6-103
Chapter 6: Configuration and alignment
Aligning antennas
When the antennas have been aligned on the center of the beam, verify that the receive level
is within the predicted range (from the installation report). If this is not the case, go back to
step 2.
The current value of receive level can be verified by using the graphical installation method
(see Graphical Install page on page 6-107) or by selecting menu option Status and monitoring
the Receive Power attribute on the System Status page.
If after repeated attempts to align, the receive level still does not lie within the predicted
range, this may be because the data provided to the prediction tool (such as PTP LINKPlanner)
is inaccurate. For example estimates of path obstructions, antenna heights or site locations
may be inaccurate. Check this data and update the prediction as necessary.
Once the antennas have been aligned correctly, tighten the integrated ODU (or connectorized
antenna) mountings. To ensure that the action of tightening does not alter antenna alignment,
continue to monitor received signal level.
Aligning separate antennas for spatial diversity
Use this procedure if a connectorized ODU is installed at either site with two separate antennas for
spatial diversity.
Procedure:
Connect the horizontal polarization antenna to the ODU, disconnect the vertical polarization
antenna, then perform Aligning antennas on page 6-103.
Connect the vertical polarization antenna to the ODU, disconnect the horizontal polarization
antenna, then perform Aligning antennas on page 6-103.
Re-connect the horizontal polarization antennas. The received signal level should increase.
Weatherproof the antenna connections at the “H” and “V” interfaces of the ODUs, as
described in Weatherproofing an N type connector on page 5-62.
UNDER DEVELOPMENT
Page 6-104
Chapter 6: Configuration and alignment
Aligning antennas
ODU installation tones
This is the first of two methods that may be used to monitor receive signal level during antenna
alignment.
The ODU emits audible tones during installation to assist with alignment. The pitch of the
alignment tone is proportional to the received power of the wireless signals. Adjust the alignment
of the unit in both azimuth and elevation until the highest pitch tone is achieved.
Note
When using ODU installation tones to align connectorized antennas, it may not be
possible to hear the tones. To overcome this problem, either use an assistant, or use a
stethoscope to give a longer reach.
The tones and their meanings are described in Table 149. In each of the states detailed in the table,
align the unit to give the highest pitch tone. The term “wanted signal” refers to that of the peer
unit being installed.

Investigate the cause of the problem.
UNDER DEVELOPMENT
Page 6-105
Chapter 6: Configuration and alignment
Aligning antennas
During alignment, the installation tones should exhibit the following behavior:
•
Band scan: When first started up and from time to time, the Master unit will carry out a band
scan to determine which channels are not in use. During this time, between 10 and 15 seconds,
the Master unit will not transmit and as a consequence of this neither will the Slave unit.
During this time the installation tone on the master unit will drop back to the band scan state,
and the Slave unit will drop back to the Scanning state with the pitch of the tone set to the
background noise level. Alignment of the unit should cease during this time.
•
Radar detection: If the unit is operating where mandatory radar avoidance algorithms are
implemented, the ranging behavior may be affected. The Master has to monitor the initially
chosen channel for 60 seconds to make sure it is clear of radar signals before transmitting. If a
radar signal is detected during any of the installation phases, a further compulsory 60 seconds
channel scan will take place as the master unit attempts to locate a new channel that is free of
radar interference.
•
Ranging: The PTP 650 Series does not require the user to enter the link range. The Master unit
typically takes less than 60 seconds to determine the length of the link being installed. The
Master unit will remain in the Scanning state until the range of the link has been established.
The Master unit will only move to the Synchronized state when the range of the link has been
established.
The Slave unit does not have a ranging process. The slave unit will change to the
Synchronized state as soon as the wanted signal is demodulated.
•
Retrying same channel: If, at the end of the ranging period, the Registered state is not achieved
due to interference or other reasons, the Master unit will retry twice more on the same channel
before moving to another available channel. Should this occur it may take a number of
minutes to establish a link in the Registered state.

Connecting to the network
Use this procedure to complete and test network connections.
Procedure:
If a management PC is connected directly to the PTP 650, disconnect it.
Confirm that all ODU Ethernet interface cables (PSU, SFP and Aux) are connected to the
correct network terminating equipment or devices.
If Main PSU Port Allocation is set to Disabled in the LAN Configuration page), it is not
necessary to connect the PSU LAN port to network terminating equipment.
Test that the unit is reachable from the network management system by opening the web
interface to the management agent, or by requesting ICMP echo response packets using the
Ping application. For in-band management, test that both units are reachable from one PC.
If the network management system is remote from the sites, either ask co-workers at the
management center to perform this test, or use remote login to the management system.
Test the data network for correct operation across the wireless link. This may be by
requesting ICMP echo response packets between hosts in the connected network segments,
or by some more structured use of network testing tools.
Monitor the Ethernet ports and wireless link to confirm that they are running normally. For
instructions, see System Summary page on page 7-2 and System Status page on page 7-3.

The maximum, mean, minimum and latest measurements of Receive
Power (dBm). See System histograms on page 7-45.
Vector Error
The maximum, mean, minimum and latest measurements of Vector
Error (dB). See System histograms on page 7-45.
Vector Error compares the received signals In phase / Quadrature (IQ)
modulation characteristics to an ideal signal to determine the composite
error vector magnitude. The expected range for Vector Error is
approximately -2 dB (NLOS link operating at sensitivity limit on BPSK
0.67) to -33 dB (short LOS link running 256 QAM 0.83).
Link Loss

(dB). See System histograms on page 7-45. The link loss is the total
attenuation of the wireless signal between the two point-to-point units.
The link loss calculation is:
Pll = PTx − PRx + g Tx + g Rx
Where:
Pll = Link Loss (dB)
PTx
= Transmit power of the remote wireless unit (dBm)
PRx
= Received signal power at the local unit (dBm)
g Tx , g R x
= Antenna gain at the remote and local units respectively
(dBi). This is the gain of the integrated or connectorized antenna.
For connectorized ODUs, the link loss calculation is modified to allow for
the increased antenna gains at each end of the link.

Modulation Mode
The modulation mode currently being used on the transmit channel.
Receive Modulation
Mode
The modulation mode currently being used on the receive channel.
Link Symmetry
A ratio that expresses the division between transmit and receive time in
the TDD frame. The first number in the ratio represents the time allowed
for the transmit direction and the second number represents the time
allowed for the receive direction.
Receive Modulation
Mode Detail
The receive modulation mode in use. For a list of values and their
meanings, see Table 156.
Range
The range between the PTP 650 Series ODUs. This is displayed in
kilometers by default, but can be changed to miles by updating the
Distance Units attribute to imperial, as described in Webpage Properties
page on page 6-64.
When a link is established, this attribute shows the lower of the license
keys at each end. For example, if this end is Full and the other end is Lite,
it shows “Lite”. To see the installed key, go to the Installation Wizard.

The Installation Wizard has been run and the unit is
armed, forcing the link to operate in the lowest
modulation mode. To remove this restriction, re-run the
Installation Wizard to disarm the unit.
Restricted Because Of Byte
Errors On The Wireless
Link
The receiver has detected data errors on the radio and
reduced the modulation mode accordingly. The radio
may achieve a higher modulation mode as shown by the
vector error, but there is some other error source,
probably RF interference.
Restricted Because Channel
Change Is In Progress
This is a transient event where the modulation mode is
temporarily reduced during a channel change.
Limited By The Wireless
Conditions
The radio is running at the maximum achievable
modulation mode given the current wireless conditions
shown by the vector error. The radio is capable of
reaching a higher modulation mode if wireless
conditions (vector error) improve.

Meaning
Aux Port Configuration Mismatch
Ethernet fragments (runt packets) have been detected
when the Aux port is in full duplex. This indicates an autonegotiation or forced configuration mismatch.
Aux Port Disabled Warning
The Aux port link has been administratively disabled via
the SNMP Interface.
Aux Port PoE Output Status
The Aux port link is down. The most likely cause is that the
unit has no Ethernet cable plugged into its Aux port.
Aux Port Status
The Aux port link is down. The most likely cause is that the
unit has no Ethernet cable plugged into its Aux port.
Capacity Variant Mismatch
The link ends are different capability variants, for example,
one is Full and the other is Med.
Ethernet Bridging Status
“Disabled” means that the link has stopped bridging
Ethernet frames because the Lowest Data Modulation
Mode is not being achieved or because the wireless link is
down.
Install Status
Signaling was received with the wrong MAC address. It is
very unusual to detect this, because units with wrongly
configured Target MAC Address will normally fail to
establish a wireless link. However, rare circumstances may
establish a partial wireless link and detect this situation.
Install Arm State
A wireless unit is in installation mode. After installation,
the wireless unit should be disarmed. This will increase the
data-carrying capacity and stop the installation tone
generator. The wireless link is disarmed from the
“Installation” process, see Disarming the units on page 6108.
Incompatible Regulatory Bands
The two linked units have different Regulatory Bands. To
clear this alarm, obtain and install license keys for the
correct country and select the same Regulatory Band at
each end of the link.
Incompatible Master and Slave
The master and slave ends of the wireless link are different
hardware products, or have different software versions. It
is very unusual to detect this because incompatible units
will normally fail to establish a wireless link. However,
some combinations may establish a partial wireless link
and detect this situation.

Alarm
Meaning
Link Mode Optimization
Mismatch
The Master and Slave ODUs are configured to use different
link mode optimization methods (one is set to IP and the
other TDM).
Main PSU Port Configuration
Mismatch
Ethernet fragments (runt packets) have been detected
when the PSU port is in full duplex. This indicates an autonegotiation or forced configuration mismatch.
Main PSU Port Disabled Warning
The PSU port link has been administratively disabled via
the SNMP Interface.
Main PSU Port Status
The PSU port link is down. The most likely cause is that the
unit has no Ethernet cable plugged into its Aux port.
No Wireless Channel Available
Spectrum Management was unable to locate a suitable
wireless channel to operate on.
Regulatory Band
The installed license key contains an invalid Regulatory
Band. The wireless unit is prohibited from operating
outside the regulated limits.
Remaining Full Capacity Time
Trial
Time remaining on the full capability trial period. Activated
when seven days or less of the trial period remain.
Remote Transparent Clock
Compatibility
The local and remote units have different IEEE 1588
transparent clock configurations. Both units must have the
same configuration for the feature to work correctly.
SFP Error
A non-OK value indicates that the SFP link is down. There
are two possible causes:
•
Either: the fiber link has been installed but disabled
(because the license key does not include SFP support),
•
Or: the SFP link could not be established even though
an SFP carrier was detected (due perhaps to a cabling
fault or the link is disabled at the link partner).
SFP Port Configuration Mismatch
Ethernet fragments (runt packets) have been detected
when the SFP port is in full duplex. This indicates an autonegotiation or forced configuration mismatch.
SFP Port Disabled Warning
The SFP port link has been administratively disabled via
the SNMP Interface.
SFP Port Status
The SFP port link is down. The most likely cause is that the
unit has no Ethernet cable plugged into its SFP port.
SNTP Synchronization failed
SNTP has been enabled but the unit is unable to
synchronize with the specified SNTP server.

Spectrum management
This section describes how to use the spectrum management pages to monitor the radio spectrum
usage of the PTP 650 link.
Spectrum Expert and Spectrum Management pages
There are two alternative web pages providing access the spectrum monitoring information:
•
the Spectrum Expert page, and
•
the Spectrum Management page.
The Spectrum Expert page is the default as it is effectively a superset of the Spectrum
Management page. However, it makes use of features only available in the most recent web
browsers. It also requires data to be sent across the wireless link, thus reducing the capacity
available for other types of traffic when the page is displayed.
Note
Internet Explorer 8 does not support the HTTP features used in the Spectrum Expert
page.
For these reasons, the PTP 650 Series may be configured to use the Spectrum Management page
instead of the Spectrum Expert page. This is done by checking the Disable Spectrum Expert (use
old Spectrum Management) control in the Web Property attribute under the Management > Web >
Web Properties menu, as shown in Figure 173.

Note
When configured to use the Spectrum Expert page, the PTP 650 is capable of
automatically detecting whether the browser accessing the unit supports the required
features. If it does not, the Spectrum Management page will be returned instead of the
spectrum Expert page. Internet Explorer 8 is not compatible with the Spectrum Expert
page.

Spectrum Management Settings
All spectrum management configuration changes are applied at the master ODU only. These
changes are then sent from the master to the slave, so that both master and slave keep identical
copies of spectrum management configuration. It is therefore possible to swap master and slave
roles on an active PTP 650 link without modifying Spectrum Management configuration.
The default channelization can be modified by varying the lower center frequency attribute in the
installation wizard, as described in Wireless Configuration page on page 6-22.
Note
Before attempting to improve the performance of the spectrum management
algorithm by changing the default configuration, consult the Cambium Point-to-Point
distributor or one of the system field support engineers.
Procedure:
•
Review the configuration attributes (Table 167)
•
Update the attributes as required. At the slave unit, only Page Refresh Period can be updated.
•
To save changes, click Submit configuration changes.

Management Page
Refresh Period
The page refreshes automatically according to the setting entered here
(in seconds).
Hopping Margin
Spectrum Management uses this margin when making a channel hop
decision. If the interference level of the target channel is lower than that
of the active channel by at least the Hopping Margin, the link will hop to
the target channel. The default setting is 3 dB in non-radar regions, or
10 dB in radar regions.
This control is available in the Spectrum Management page only.

Spectrum management
Attribute
Meaning
Asymmetric DSO
Only displayed in non-radar regions when DSO is enabled. The default
configuration of symmetric operation constrains the link to operate
symmetrically, using the same transmit and receive channels. When in
symmetric mode the slave unit will always follow the master. If the
master moves to a new channel the slave will hop to the same channel.
When the Point-to-Point link is configured as an asymmetric link both
the master and slave are free to select the best channel from their own
set of local interference metrics.
Spectrum
Management
Control
Only displayed in radar regions. The options are DFS and DFS with DSO.
Hopping Period
The Spectrum Management algorithm evaluates the metrics every
“Hopping Period” seconds (180 seconds by default) looking for a
channel with lower levels of interference. If a better channel is located,
Spectrum Management performs an automated channel hop. If SNMP or
SMTP alerts are enabled an SNMP TRAP or an email alert is sent
warning the system administrator of the channel change.
Hopping Counter
(not configurable)
This is used to record the number of channel hops. The number in the
(+) brackets indicates the number of channel changes since the last
screen refresh.
Interference
Threshold
Spectrum Management uses the interference threshold to perform
instantaneous channel hops. If the measured interference on a channel
exceeds the specified threshold, then DSO will instruct the wireless to
immediately move to a better channel. If a better channel cannot be
found the PTP 650 Series will continue to use the current active channel.

Interpreting the receive spectrum plot
The Spectrum Expert page has two graphical plots:
•
Local Receive Spectrum
•
Peer Receive Spectrum
A more detailed example of one of these plots is shown in Figure 174.
For more information, select the Help hyperlink at the top right of the Spectrum Expert page and
follow the instructions.
X axis and Y axis
The X-axis shows a stylized view of the selectable wireless channels. Note that the distance
between adjacent channels may be smaller than the channel bandwidth. If this is the case,
adjacent channels overlap. Channels are displayed separately for clarity. The axis is labeled using
the channel center frequencies in MHz. The Y-axis shows the interference power levels from –100
to –40 dBm.
Channel states
The active channel (Channel 9 in Figure 174) is always marked using hatched green and white lines
on the Spectrum Management page or solid green on the Spectrum Expert page. The width of the
hatching is directly proportional the channel bandwidth or spectral occupancy of the channel.
The individual channel metrics are displayed using a colored bar and an “I” bar. The colored bar
represents the channel state (Table 168).

Key metrics
The “I” bar and top of the colored bar represent three key metrics (Table 169). The vertical part of
the “I” bar represents the statistical spread between the peak and the mean of the statistical
distribution.
The arithmetic mean is the true power mean and not the mean of the values expressed in dBm.
Spectrum Management uses the 99.9% Percentile as the prime interference measurement. All
subsequent references to interference level refer to this percentile measurement.

Mean of Means
The arithmetic mean of the measured means
during a quantization period. The mean of means
is a coarse measure of signal interference and
gives an indication of the average interference
level measured during the quantization period.
The metric is not very good at predicting
intermittent interference and is included to show
the spread between the Mean of Means, the

Interpreting the histogram plot
The histogram plot indicates the percentage of the measurements in the selected measurement
period where the interference level for the selected channel is at a given level (Figure 187).
The channel and measurement period are selected as described in Selecting a Channel and a Time
period on page 7-40 The combined selection is indicated graphically by a pair of brackets in the
Waterfall plot, and in text form on the top right of the Histogram plot, as shown in Figure 186.
The X-axis corresponds to a percentage of the measurements in the measurement period on a
logarithmic scale.
The Y-axis corresponds to actual interference level in dBm.
The bar for each each power level is of the same color as in the Interference Waterfall plot.

System histograms
The System Histograms section of the System Statistics page (Figure 188) contains eight
diagnostic attributes that are presented as arrays of four elements (Table 172).
Figure 188 System Histograms section of the System Statistics page
The element arrays represent the following:
•
Max: The maximum value measured over the last hour.
•
Mean: The mean of a set of values recorded at one second intervals over the last hour.
•
Min: The minimum value measured over the last hour.
•
Latest: The latest value measured.
The values are calculated over the time that has elapsed since the link was established or since the
measurement period was reset.
Use the Diagnostics Plotter page on page 7-58 to plot these attributes against time. Use the
Generate Downloadable Diagnostics page on page 7-59 to extract historical data for these

Table 172 System Histogram attributes in the System Statistics page
Attribute
Meaning
Transmit Power
The transmit power histogram, calculated over a one hour period.
Receive Power
The receive power histogram, calculated over a one hour period.
Vector Error
The vector error measurement compares (over a one hour period) the
received signal IQ modulation characteristics to an ideal signal to determine
the composite vector error magnitude.
Link Loss
Link loss calculated (over a one hour period) as follows:
Peer_Tx_Power (dBm) – Local_Rx_Power (dBm) + 2 x Antenna_Pattern (dBi)
Signal Strength
Ratio
The Signal Strength Ratio (calculated over a one hour period) is:
Power received by the vertical antenna input (dB) ÷
Power received by the horizontal antenna input (dB)
This ratio is presented as: max, mean, min, and latest. The max, min and
latest are true instantaneous measurements; the mean is the mean of a set of
one second means.
Signal Strength Ratio is an aid to debugging a link. If it has a large positive or
negative value then investigate the following potential problems:
•
An antenna coaxial lead may be disconnected.
•
When spatial diversity is employed, the antenna with the lower value may
be pointing in the wrong direction.
•
When a dual polar antenna is deployed, the antenna may be directed
using a side lobe rather than the main lobe.
When there is a reflection from water on the link and spatial diversity is
employed, then one expects large, slow swings in Signal Strength Ratio.
This indicates the antenna system is doing exactly as intended.
Transmit,
Receive and
Aggregate Data
Rates
The data rates in the transmit direction, the receive direction and in both
directions, expressed in Mbps (max, mean, min, and latest). The max, min
and latest are true instantaneous measurements. The mean is the mean of a
set of one second means.
Histogram

Testing link end hardware
Testing link end hardware
This section describes how to test the link end hardware when it fails on startup or during
operation.
Before testing link end hardware, confirm that all outdoor drop cables, that is those that connect
the ODU to equipment inside the building, are of the supported type, as defined in Outdoor copper
Cat5e Ethernet cable on page 2-37.
AC Power Injector LED sequence
When the AC Power Injector is connected to the AC mains, the Power (green) LED should
illuminate within 5 seconds of connection. If this does not happen, the AC injector is either not
receiving power from the AC mains or there is a fault on the drop cable causing the power injector
to sense an over current condition on the ODU output connector.
Action: Remove the ODU cable from the PSU and observe the effect on the power LED:
•
If the power LED does not illuminate, confirm that the mains supply is working, for example
check the plug and fuse (if fitted). If the power supply is working, report a suspected PSU fault
to Cambium Networks.
•
If the Power LED does illuminate, perform Test resistance in the drop cable on page 5-25.
AC+DC Enhanced power injector LED sequence
For the AC+DC Enhanced power injector, the expected power-up LED sequence is:
•
The Power (green) LED illuminates steadily.
•
After about 45 seconds, the Ethernet (yellow) LED blinks slowly 10 times.
•
The Ethernet (yellow) LED illuminates steadily, then blinks randomly to show Ethernet activity.
If this sequence does not occur, take appropriate action depending on the LED states:
•
Power LED is off on page 8-3
•
Power LED is blinking on page 8-3
•
Ethernet LED did not blink 10 times on page 8-3
•
Ethernet LED blinks ten times then stays off on page 8-4
•
Ethernet LED blinks irregularly on page 8-4 (for example a short blink followed by a long blink)
•
Power LED is on, Ethernet LED blinks randomly on page 8-4
If a fault is suspected in the ODU-PSU drop cable, perform Test resistance in the drop cable on
page 5-25.
UNDER DEVELOPMENT
Page 8-2
Chapter 8: Troubleshooting
Testing link end hardware
Power LED is off
Meaning: Either the PSU is not receiving power from the AC/DC outlet, or there is a wiring fault in
the ODU cable.
Action: Remove the ODU cable from the PSU and observe the effect on the Power LED:
•
If the Power LED does not illuminate, confirm that the mains power supply is working, for
example, check the plug and fuse (if fitted). If the power supply is working, report a suspected
PSU fault to Cambium Networks.
•
If the Power LED does illuminate, perform Test resistance in the drop cable on page 5-25.
Power LED is blinking
Meaning: The PSU is sensing there is an overload on the ODU port; this could be caused by a
wiring error on the drop cable or a faulty ODU.
Action: Remove the ODU cable from the PSU. Check that pins 4&5 and 7&8 are not crossed with
pins 1&2 and 3&6. Check that the resistance between pins 1&8 is greater than 100K ohms. If either
check fails, replace or repair the ODU cable.
Ethernet LED did not blink 10 times
Meaning: The ODU flashes the LED on the AC+DC Enhanced Power Injector 10 times to show that
the ODU is powered and booted correctly.
Action:
Remove the ODU cable from the PSU. Examine it for signs of damage. Check that the ODU
cable resistances are correct, as specified in Test resistance in the drop cable on page 5-25. If
the ODU cable is suspect, replace it.
Use the LPU (if installed) to check that power is available on the cable to the ODU. Access the
connections by rotating the LPU lid as shown (slacken the lid nut but do not remove it):
UNDER DEVELOPMENT

Chapter 8: Troubleshooting
Testing link end hardware
Check that test point P1 on the LPU PCB corresponds to pin 1 on the RJ45. Repeat for points
P2 to P8. This test is only valid if both the PSU and the ODU are disconnected.
Reconnect the ODU cable to the PSU.
Check that the PWR LED near the top right of the LPU PCB is illuminated to indicate power in
the Ethernet cable.
If any test fails, replace or repair the cable that connects the PSU to the LPU or ODU.
Ethernet LED blinks ten times then stays off
Meaning: There is no Ethernet traffic between the PSU and ODU.
Action: The fault may be in the LAN or ODU cable:
•
Confirm that Ethernet traffic is connected to the AC+DC injector LAN port, confirm the cable is
not faulty, replace if necessary.
•
If the LAN connection to the AC+DC power injector is working, check the drop cable is correctly
wired using a suitable cable tester. Repeat the drop cable tests on page Test resistance in the
drop cable on page 5-25.
Ethernet LED blinks irregularly
Meaning: If the Ethernet LED blinks irregularly, for example two rapid blinks followed by a longer
gap, this indicates that the ODU has booted in recovery mode. The causes may be: installation
wiring, or a corrupt ODU software load, or sufficient time has not been allowed between a repeat
power up.
Action: Refer to Recovery mode on page 7-60.
Power LED is on, Ethernet LED blinks randomly
Meaning: Both LEDs are in their normal states, implying that the PSU is receiving power from the
AC/DC outlet and there is normal Ethernet traffic between the PSU and ODU.
Action: If, in spite of this, a fault is suspected in the link end hardware:
•
If the Ethernet connection to the network is only 100BASE-TX, when 1000BASE-T is expected:
remove the ODU cable from the PSU, examine it, and check that the wiring to pins 4&5 and
7&8 is correct and not crossed.
•

Test Ethernet packet errors reported by ODU
Log into the unit and click Administration, Statistics, Detailed Counters. Click Reset System
Counters at the bottom of the page and wait until the Ethernet Rx Packets counter has reached 1
million (the count will only update when the page is refreshed. If the counter does not increment
or increments too slowly, because for example the PTP 650 is newly installed and there is no
offered Ethernet traffic, then abandon this procedure and consider using the procedure Test ping
packet loss on page 8-6.
Read the Ethernet Rx Crc And Align counter. The test has passed if this is less than 10.
Test Ethernet packet errors reported by managed switch or router
If the ODU is connected to a managed Ethernet switch or router, it may be possible to monitor the
error rate of Ethernet packets. Please refer to the user guide of the managed network equipment.
The test has passed if the rate of packet errors reported by the managed Ethernet switch or router
is less than 10 in 1 million packets.
Test ping packet loss
Using a computer, it is possible to generate and monitor packets lost between the PSU and the
ODU. This can be achieved by executing the Command Prompt application which is supplied as
standard with Windows and MAC operating systems.
Caution
This procedure disrupt network traffic carried by the PTP 650 under test:
Procedure:
Ensure that the IP address of the computer is configured appropriately for connection to
the PTP 650 under test, and does not clash with other devices connected to the network.
If the PSU is connected to an Ethernet switch or router then connect the computer to a spare
port, if available.
If it is not possible to connect the computer to a spare port of an Ethernet switch or router,
then the PSU will need to be disconnected from the network in order to execute this test:
•
Disconnect the PSU from the network.
•
Connect the computer directly to the LAN port of the PSU.
On the computer, open the Command Prompt application.

Send 1000 ping packets of length 1500 bytes. The process will take 1000 seconds, which is
approximately 17 minutes.
If the computer is running a Windows operating system, this is achieved by typing (for an IPv6
address, use the ping6 command):
ping –n 1000 –l 1500 
where  is the IP address of the PTP 650 ODU under test.
If the computer is running a MAC operating system, this is achieved by typing:
ping –c 1000 –s 1492 
where  is the IP address of the PTP 650 ODU under test.
Record how many Ping packets have been lost. This is reported by Command Prompt on
completion of the test.
The test has passed if the number of lost packets is less than 2.

Testing the radio link
Testing the radio link
This section describes how to test the link when there is no radio communication, when it is
unreliable, when the data throughput rate is too low, or when a unit is causing radio or TV
interference. It may be necessary to test the units at both ends of the link.
No activity
If there is no wireless activity, proceed as follows:
Check for Alarm conditions on Home page.
Check that the software at each end of the link is the same version.
Check that the Target Mac address is correctly configured at each end of the link.
Check Range.
Check Tx Power.
Check License keys to ensure that both units are the same product variant.
Check Master/Slave status for each unit and ensure that one unit is Master and the other unit
is slave.
Check that the link is not obstructed or the ODU misaligned.
Check the DFS page at each end of the link and establish that there is a quiet wireless channel
to use.
10
If there are no faults found in the configuration and there is absolutely no wireless signal,
retry the installation procedure.
11
If this does not work then report a suspected ODU fault to Cambium Networks.
Some activity
If there is some activity but the link is unreliable or does not achieve the data rates required,
proceed as follows:
Check that the interference has not increased using the DSO measurements.
If a quieter channel is available check that it is not barred.
Check that the path loss is low enough for the communication rates required.
Check that the ODU has not become misaligned.

Testing PTP-SYNC
LEDs do not illuminate
Meaning: The PTP-SYNC unit is not powered up.
Action: Ensure that there is a cable connection between the PSU ODU interface and the PIDU IN
interface of the PTP-SYNC unit. Confirm that the PSU is powered up.
STATUS LED is on steady
Meaning: There is power but no satellite lock. This probably indicates that a 1PPS synchronization
pulse is not detected by the PTP-SYNC unit.
Action: Depending on system configuration, take one of the following actions:
•
System using a GPS receiver module - Ensure that there is a cable connection between the
PTP-SYNC GPS/SYNC IN interface and the LPU, also that there is a cable connection between
the LPU and the GPS receiver module. Check that the GPS receiver module has an
uninterrupted view of the sky.
•
System using an alternative 1PPS timing source - Ensure that there is a cable connection
between the PTP-SYNC GPS/SYNC IN or 1PPS IN interface and the 1PPS timing source.
•
On cluster slave units – Ensure that there is a cable connection between the slave GPS/SYNC
IN interface and the SYNC OUT interface of the preceding unit in the chain.
STATUS LED double-blinks
Meaning: There may be a fault in the GPS/SYNC IN or 1PPS IN cables.
Action: Check the GPS wiring in accordance with Table 43.
ODU LED does not illuminate within 90 seconds
Meaning: There may be no communication between PTP-SYNC and ODU.
Action: Ensure that the PTP-SYNC ODU OUT interface is connected to the ODU (and LPUs if
installed) via the drop cable.
ODU LED blinks red
Meaning: Error in communication with ODU. Possible causes are: fault in the ODU or PSU cable,
maximum recommended cable lengths exceeded, or TDD synchronization is not enabled at the
ODU.
Action: Confirm that the ODU and PSU cables are not too long: see Ethernet standards and cable
lengths on page 2-36. Check the ODU cable wiring by following the procedure described in Test
resistance in the drop cable on page 5-25.

Testing a TDM link
Performing a TDM loopback test
The loopback test allows a TDM data stream to be looped back at the copper or wireless interface.
A typical T1 or E1 installation test includes a copper loopback on the local unit followed by a
wireless loopback on the remote unit.
Note
The TDM Configuration page is only available when the TDM interface is enabled and
the unit is rebooted (Interface Configuration page on page 6-14).
Procedure:
•
Select menu option System > Configuration > TDM Configuration (Figure 128).
•
Set the TDM Channel Loopback n attribute (where “n” is in the range 1 to 8) to Copper or
Wireless (Table 129).
•
Click Submit Updated TDM Configuration.
•
Perform loopback tests. The System Summary page displays alarms indicating the presence of
loopbacks on each affected TDM channel (Alarms on page 7-17).
•
Set the TDM Channel Loopback n attribute (where “n” is in the range 1 to 8) to None (Table
129).
•
Click Submit Updated TDM Configuration.
Checking for 1000BASE-T operation
If the ODU port has negotiated a link at 100BASE-T, the NIDU will not send or receive TDM data
and will not bridge customer data traffic. Check that the Ethernet drop cable between the ODU and
the PSU, and the network cable between the PSU and the NIDU have successfully negotiated
operation at 1000BASE-T. On the System Status page, review Main PSU Port Speed and Duplex
(Figure 166) and confirm that it is set to 1000 Mbps Full Duplex.
