•
Supplemental installation information on page 5-33 contains detailed installation procedures
that are not included in the above topics, such as how to strip cables, create grounding points
and weatherproof connectors.
Note
These instructions assume that LPUs are being installed from the PTP 650 LPU and
grounding kit (Cambium part number C000065L007). If the installation does not
require LPUs, adapt these instructions as appropriate.
If LPUs are being installed, only use the five black-capped EMC cable glands supplied
in the LPU and grounding kit. The silver-capped cable glands supplied in the ODU kits
must only be used in PTP 650 installations which do not require LPUs.

Safety
Safety
Warning
To prevent loss of life or physical injury, observe the following safety guidelines. In no
event shall Cambium Networks be liable for any injury or damage caused during the
installation of the Cambium PTP 650. Ensure that only qualified personnel install a PTP
650 link.
Power lines
Exercise extreme care when working near power lines.
Working at heights
Exercise extreme care when working at heights.
PSU
Always use one of the Cambium PTP 650 Series power supply units (PSU) to power the ODU.
Failure to use a Cambium supplied PSU could result in equipment damage and will invalidate the
safety certification and may cause a safety hazard.
Grounding and protective earth
The Outdoor Unit (ODU) must be properly grounded to protect against lightning. It is the user’s
responsibility to install the equipment in accordance with national regulations. In the USA follow
the requirements of the National Electrical code NFPA 70-2005 and 780-2004 Installation of
Lightning Protection Systems. In Canada, follow Section 54 of the Canadian Electrical Code. These
codes describe correct installation procedures for grounding the outdoor unit, mast, lead-in wire
and discharge unit, size of grounding conductors and connection requirements for grounding
electrodes. Other regulations may apply in different countries and therefore it is recommended
that installation of the outdoor unit be contracted to a professional installer.
Page 5-2
Chapter 5: Installation
Safety
DC supply
To power the ODU from a DC supply, use the AC+DC Enhanced Power Injector (PSU) (Cambium
part number C000065L002). Ensure that the DC power supply meets the requirements specified in
PSU DC power supply on page 3-12.
Powering down before servicing
Before servicing PTP 650 equipment, always switch off the power supply and unplug it from the
PSU.
Do not disconnect the RJ45 drop cable connectors from the ODU while the PSU is connected to the
power supply. Always remove the AC or DC input power from the PSU.
Primary disconnect device
The main power supply is the primary disconnect device. The AC+DC Enhanced power injector is
fused on the DC input. Some installations will also require an additional circuit breaker or isolation
switch to be fitted in the DC supply.
External cables
Safety may be compromised if outdoor rated cables are not used for connections that will be
exposed to the outdoor environment. For outdoor copper Cat5e Ethernet interfaces, always use
Cat5e cable that is gel-filled and shielded with copper-plated steel. Alternative types of drop cable
are not supported by Cambium Networks.
Drop cable tester
The PSU output voltage may be hazardous in some conditions, for example in wet weather. Do
NOT connect the drop cable tester to the PSU, either directly or via LPUs.
RF exposure near the antenna
Strong radio frequency (RF) fields will be present close to the antenna when the transmitter is on.
Always turn off the power to the ODU before undertaking maintenance activities in front of the
antenna.
Page 5-3
Chapter 5: Installation
Safety
Minimum separation distances
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. Never work in front of the antenna when the ODU is
powered. Install the ODUs so as to provide and maintain the minimum separation distances from
all persons. For minimum separation distances, see Calculated distances and power compliance
margins on page 4-25.
Grounding and lightning protection requirements
Ensure that the installation meets the requirements defined in Grounding and lightning protection
on page 3-8.
Grounding cable installation methods
To provide effective protection against lightning induced surges, observe these requirements:
•
Grounding conductor runs are as short, straight and smooth as possible, with bends and
curves kept to a minimum.
•
Grounding cables must not be installed with drip loops.
•
All bends must have a minimum radius of 203 mm (8 in) and a minimum angle of 90°. A
diagonal run is preferable to a bend, even though it does not follow the contour or run parallel
to the supporting structure.
•
All bends, curves and connections must be routed towards the grounding electrode system,
ground rod, or ground bar.
•
Grounding conductors must be securely fastened.
•
Braided grounding conductors must not be used.
•
Approved bonding techniques must be used for the connection of dissimilar metals.
Siting ODUs and antennas
ODUs and external antennas are not designed to survive direct lightning strikes. For this reason
they must be installed in Zone B as defined in Lightning protection zones on page 3-8. Mounting in
Zone A may put equipment, structures and life at risk.

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 4-23, 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 7-31.
Selecting configuration options
Use the installation report to determine which configuration options are required. Refer to PTP
LINKPlanner on page 3-21.

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 70 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.
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.
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 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.

This is only displayed when Spectrum Management Control is set to
Fixed Frequency. Limits frequency selection to the unit’s default raster
setting.
Fixed Tx Frequency,
Fixed Rx Frequency
This is only displayed when Spectrum Management Control is set to
Fixed Frequency. The settings must be compatible at each end of the link.
Once configured, the spectrum management software will not attempt to
move the wireless link to a channel with lower co-channel or adjacent
channel interference. Therefore this mode of operation is only
recommended for deployments where the installer has a good
understanding of the prevailing interference environment.
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)

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 6-49.

Caution
Before configuring a VLAN for management interfaces, ensure that the VLAN is
accessible, otherwise the unit will be inaccessible after the next reboot.
Caution
Before configuring in-band management, ensure that the Master and Slave units are
configured with different IP addresses, otherwise the management agent will not be
able to distinguish the two units.
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), but only 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.
Procedure:
Review and update the attributes: IP Interface (Table 72); Main PSU or Aux Port (Table 73);
Bridging (Table 74).
To save changes, click Submit Updated System Configuration. Some updates will cause the
system to reboot.
If Main PSU Port Allocation has been changed to Disabled or Data Only, connect the
management PC to whichever port (Aux or SFP) has been set to Data and In-Band
Management or Out-of-Band Local Management.
If IP Address, Subnet Mask or Gateway IP Address have been changed, reconfigure the local
management PC to use an IP address that is valid for the network. Refer to Configuring the
management PC on page 6-5.
If IP Address has been changed, use the new IP address to log into the unit.

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 6-5.
Power up the remote unit.
Log into the local unit as described in Logging into the web interface on page 6-7.
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 6-10.
Page 6-87
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 6-89 before starting alignment.
Note
For improved radio performance, mount the integrated ODU at 45 degrees to the
vertical, as shown in Installing the ODU and top LPU on page 5-5.
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 6-90
•
Graphical Install page on page 6-92
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.
Page 6-88
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 6-92) 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 6-88.
Connect the vertical polarization antenna to the ODU, disconnect the horizontal polarization
antenna, then perform Aligning antennas on page 6-88.
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 5-37.
Page 6-89
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 96. 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.

Caution
If, when in the Synchronized or Registered state, the tone varies wildly, there may be
interference or a fast fading link. Installing in this situation may not give a reliable link.
Investigate the cause of the problem.
Page 6-90
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.

This section describes other configuration tasks.
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.

Table 102 System alarms
Alarm
Meaning
Regulatory Band
The installed license key contains an invalid Regulatory
Band. The wireless unit is prohibited from operating
outside the regulated limits.
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 693.
Unit Out Of Calibration
The unit is out of calibration and must be returned to the
factory using the RMA process for re-calibration.
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.
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.
No Wireless Channel Available
Spectrum Management was unable to locate a suitable
wireless channel to operate on.
SNTP Synchronization failed
SNTP has been enabled but the unit is unable to
synchronize with the specified SNTP server.

Alarm
Meaning
Wireless Link Disabled Warning
The wireless link has been administratively disabled via the
SNMP Interface. The wireless interface MIB-II
ifAdminStatus attribute has been set to DOWN. To enable
the Ethernet interface, set the ifAdminStatus attribute to
UP.
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.
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.
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 Disabled Warning
The Aux port link has been administratively disabled via
the SNMP Interface.
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.
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).
Syslog Enabled/ Disabled
Warning
The local log of event messages has been enabled or
disabled.
Syslog Local Nearly Full
The local log of event messages is nearly full.
Page 7-14
Chapter 7: Operation

Alarm
Meaning
Syslog Local Wrapped
The local log of event messages is full and is now being
overwritten by new messages.
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.
Syslog Client Enabled/Disabled
Warning
The local syslog client has been enabled or disabled.
Ethernet Bridging Status
“Disabled” means that the link has stopped bridging
Ethernet frames because the Lowest Ethernet Modulation
Mode is not being achieved or because the wireless link is
down.
Remaining Full Capacity Time
Trial
Time remaining on the full capability trial period. Activated
when seven days or less of the trial period remain.
Capacity Variant Mismatch
The link ends are different capability variants, for example,
one is Full and the other is Med.
Email alerts
The management agent can be configured to generate alerts by electronic mail when certain
events occur. The alerts are defined in Table 103.
Table 103 Email alerts
Alert
Meaning
Wireless Link Up Down
There has been a change in the status of the wireless link.
Channel Change
DFS has forced a change of channel.
DFS Impulse Interference
DFS has detected impulse interference.
Enabled Diagnostic Alarms
Diagnostic alarms have been enabled.
Main PSU Port Up Down
There has been a change in the status of the PSU data port.

Spectrum management
This section describes how to use the spectrum management pages to monitor the radio spectrum
usage of the PTP 650 link.
Spectrum Management page
Menu option: System > Spectrum Management (Figure 115 and Figure 116).
Use this page to view and configure spectrum usage. The width of the vertical green bar
represents the channel width (10 MHz illustrated).
Figure 115 Spectrum Management page (master unit)
Page 7-20
Chapter 7: Operation
Spectrum management
Figure 116 Spectrum Management page (slave unit)
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 6-15.
Page 7-21
Chapter 7: Operation
Spectrum management
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 105)
•
Update the attributes as required. At the slave unit, only Page Refresh Period can be updated.
•
To save changes, click Submit configuration changes.
Table 105 Spectrum Management attributes
Attribute
Meaning
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.
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 (not
configurable)
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
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.
Page 7-22
Chapter 7: Operation
Spectrum management
Attribute
Meaning
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.
(Default –85 dBm).
Channel Bandwidth
(not configurable)
This shows the value of the variable channel bandwidth selected.
Interpreting the spectrum management plots
The Spectrum Management pages at the master and slave (Figure 115 and Figure 116) display two
graphical plots:
•
Local Receive Channel Spectrum
•
Peer Receive Channel Spectrum
A more detailed example of one of these plots is shown in Figure 117.
Figure 117 Example spectrum management plot

Chapter 7: Operation
Spectrum management
X axis and Y axis
The X-axis shows a stylized view of the selectable wireless channels. Adjacent channels on the
display have a 10 MHz 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 5 in Figure 117) is always marked using hatched green and white
lines. The width of the hatching is directly proportional the channel bandwidth 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 106).
Table 106 Channel states represented in the spectrum management plot
Color

Key metrics
The “I” bar and top of the colored bar represent three key metrics (Table 107). The vertical part of
the “I” bar represents the statistical spread between the peak and the mean of the statistical
distribution.
Table 107 Key metrics represented in the spectrum management plot
Metric
Description
How represented
Peak of Means
The largest mean interference measurement
encountered during the quantization period. The
peak of means is useful for detecting slightly
longer duration spikes in the interference
environment.
Upper horizontal
bar.
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
99.9% Percentile and the Peak of Means.
Lower horizontal
bar.
99.9% Percentile
of the Means
The value of mean interference measurement
which 99.9% of all mean measurements fall
below, during the quantization period. The 99.9%
percentile metric is useful for detecting short
duration repetitive interference that by its very
nature has a minimal effect of the mean of means.
Top of the colored
bar.
Note
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.

Chapter 7: Operation
Spectrum management
Spectrum management in fixed frequency mode
When the link is operating in fixed frequency mode, the Spectrum Management page uses two
visual cues (Figure 118). The main page title has the “Fixed Frequency Mode” suffix and the
selected channels are identified by a red capital “F”.
Figure 118 Spectrum Management Fixed Frequency Mode page
Channel barring is disabled in fixed frequency mode; it is not required as dynamic channel
hopping is prohibited in this mode.
The only controls available to the master are the Page Refresh Period and Interference Threshold
attributes. They will have no effect on the operation of the wireless link and will only effect the
generation of the channel spectrum graphics.
The active channel history menu is removed in this mode of operation, as channel hopping is
prohibited.
Page 7-26
Chapter 7: Operation
Spectrum management
Spectrum management in radar avoidance mode
When the link is operating in radar avoidance mode, the Spectrum Management page (Figure 119
and Figure 120) contains the following additional information:
•
The main page title has the “Radar Avoidance” suffix.
•
The only controls available to the master are the Interference Threshold attribute. This has no
effect on the operation of the wireless link and will only affect the generation of the channel
spectrum graphics.
•
Extra color coding of the interference histogram is provided (Table 108).
When operating with RTTT (Road transport and Traffic Telematics) Avoidance enabled or other
regulatory restrictions on channel usage, the page contains the following additional information:
•
All channels marked with a “no entry” symbol with their associated statistics colored black are
the prohibited channels. These channels are never used to host the wireless link, but CAC
measurements are still taken so that adjacent channel biases can be calculated correctly and so
the user can see if other equipment is in use.

Table 110 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.

Chapter 8: Troubleshooting
This chapter contains procedures for identifying and correcting faults in a PTP 650 link. These
procedures can be performed either on a newly installed link, or on an operational link if
communication is lost, or after a lightning strike.
The following topics are described in this chapter:
•
Testing link end hardware on page 8-2 describes how to test the link end hardware, either
when it fails on startup, or after a lightning strike.
•
Testing the radio link on page 8-9 describes how to test the link when there is no radio
communication, or when it is unreliable, or when the data throughput rate is too low.
Page 8-1
Chapter 8: Troubleshooting
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 2-21.
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 5-20.
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 8-5 (for example a short blink followed by a long blink)
•
Power LED is on, Ethernet LED blinks randomly on page 8-5
If a fault is suspected in the ODU-PSU drop cable, perform Test resistance in the drop cable on
page 5-20.
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 5-20.
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 5-20. 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):
Page 8-3
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 5-20.
Page 8-4
Chapter 8: Troubleshooting
Testing link end hardware
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 7-44.
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.
•
Perform Ethernet packet test on page 8-6.
Page 8-5
Chapter 8: Troubleshooting
Testing link end hardware
Ethernet packet test
Follow the Ethernet packet test flowchart (Figure 134) and procedures below.
Figure 134 Ethernet packet test flowchart
Page 8-6
Chapter 8: Troubleshooting
Testing link end hardware
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 8-7.
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.
Page 8-7
Chapter 8: Troubleshooting
Testing link end hardware
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.

Chapter 8: Troubleshooting
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.
Page 8-9
Chapter 8: Troubleshooting
Testing the radio link
Radio and television interference
If a PTP 650 unit is interfering with radio or television reception (this can be determined by turning
the equipment off and on), attempt the following corrective actions:
•
Realign or relocate the antenna.
•
Increase the separation between the affected equipment and antenna.
•
Connect the ODU and PSU power supply into a power outlet on a circuit different from that to
which the receiver is connected.
•
Contact Cambium Point-to-Point for assistance.
