Radio Recovery
This section describes:
• How to recover a PMP/PTP 450i unit from configuration errors or software image corruption
• How to override a PMP/PTP 450 unit from forgotten IP address and password to factory default
Recovery Console – PMP/PTP 450i
Use this procedure to enter recovery console manually.
Note
The unit may enter recovery console automatically, in response to some failures.
Note
Once the unit has entered recovery, it will switch back to normal operation if no access
has been made to the recovery web page within 30 seconds.
Procedure 32
Recovery mode
1
Apply power to PSU for at least 10 seconds.
2
Remove power for two seconds.
3
Re
-apply power to the PSU.
4
When the unit is in recovery mode, access the web interface by entering the default IP
address
169.254.1.1
. The Recovery Image Warning page is displayed.
5
Review the
Boot Selection (Table 201).

Overriding Forgotten IP Address or Password - PMP/PTP 450
A small adjunctive product allows to temporarily override some PMP/PTP 450 ODU settings and
thereby regain control of the module by powering the module on with the plug inserted into the
unit’s synchronization (RJ11) port. This override plug is needed for access to the module in any of
the following cases:
• You have forgotten either
o the IP address assigned to the ODU.
o the password that provides access to the ODU.
• The ODU has been locked by the No Remote Access feature.
• You want local access to a module that has had the 802.3 link disabled in the Configuration
page.
Chapter 9: Operation Radio Recovery
Page 9-61
You can configure the module such that, when it senses the override plug, it responds by either
• resetting the LAN1 IP address to 169.254.1.1, allowing access through the default configuration
without changing the configuration, whereupon you will be able to view and reset any non-
default values as you wish.
• resetting all configurable parameters to their factory default values.
Using the Default/Override Plug
The following section details usage of the override plug to regain access to PMP/PTP 450 ODU.
Note
While the override plug is connected to a PMP/PTP 450 ODU, the ODU can neither
register nor allow registration of another ODU.
To regain access to the module, perform the following steps.
Procedure 33
Recovery mode
1
Insert the override plug into the RJ-11 GPS utility port of the module.
2
Power cycle by removing, then re-inserting, the Ethernet cable.
RESULT: The module boots with the default IP address of 169.254.1.1, password
fields blank, and all other configuration values as previously set.
3
Wait approximately 30 seconds for the boot to complete.
4
Remove the override plug.
5
Set passwords and IP address as desired.
6
Change configuration values if desired.
7
Click the Save Changes button.
8
Click the Reboot button.

FCC specific information
FCC compliance testing
With GPS synchronization installed, the system has been tested for compliance to US (FCC)
specifications. It has been shown to comply with the limits for emitted spurious radiation for a
Class B digital device, pursuant to Part 15 of the FCC Rules in the USA. These limits have been
designed to provide reasonable protection against harmful interference. However the equipment
can radiate radio frequency energy and, if not installed and used in accordance with the
instructions, may cause harmful interference to other radio communications. There is no
guarantee that interference does not occur in a particular installation.
Note
A Class B Digital Device is a device that is marketed for use in a residential
environment, notwithstanding use in commercial, business and industrial
environments.
Note
Notwithstanding that Cambium has designed (and qualified) the PMP/PTP 450
platform products to generally meet the Class B requirement to minimize the potential
for interference, the PMP/PTP 450 platform product range is not marketed for use in a
residential environment.

Chapter 11: Troubleshooting
This chapter contains procedures for identifying and correcting faults in a PMP/PTP 450 platform
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:
• General troubleshooting procedure on page 11-23
• Troubleshooting procedures on page 11-26
• Power-up troubleshooting on page 11-35
• Registration and connectivity troubleshooting on page 11-36

General troubleshooting procedure
General planning for troubleshooting
Effective troubleshooting depends in part on measures that you take before you experience
trouble in your network. Cambium recommends the following measures for each site:
• Identify troubleshooting tools that are available at your site (such as a protocol analyzer).
• Identify commands and other sources that can capture baseline data for the site. These may
include:
o Ping
o Tracert or traceroute
o Link Capacity Test results
o Throughput data
o Configuration tab captures
o Status tab captures
o Session logs
o Web browser used
• Start a log for the site.
• Include the following information in the log:
o Operating procedures
o Site-specific configuration records
o Network topology
o Software releases, boot versions and FPGA firmware versions
o Types of hardware deployed
o Site-specific troubleshooting processes
o Escalation procedures
• Capture baseline data into the log from the sources listed above
Chapter 11: Troubleshooting General troubleshooting procedure
Page 11-24
General fault isolation process
Effective troubleshooting also requires an effective fault isolation methodology that includes the
following:
• Attempting to isolate the problem to the level of a system, subsystem, or link, such as
o AP to SM
o AP to CMM4
o AP to GPS
o Backhaul(BH)
o Backhaul(BH) to CMM4
o Power
• Researching Event Logs of the involved equipment
• Interpreting messages in the Event Log
• Answering the questions listed in the following sections.
• Reversing the last previous corrective attempt before proceeding to the next.
• Performing only one corrective attempt at a time.
Questions to help isolate the problem
When a problem occurs, attempt to answer the following questions:
• What is the history of the problem?
o Have we changed something recently?
o Have we seen other symptoms before this?
• How wide-spread is the symptom?
o Is the problem on only a single SM? (If so, focus on that SM.)
o Is the problem on multiple SMs? If so
is the problem on one AP in the cluster? (If so, focus on that AP)
is the problem on multiple, but not all, APs in the cluster? (If so, focus on those APs)
is the problem on all APs in the cluster? (If so, focus on the CMM4 and the GPS signal.)
• Based on data in the Event Log
o does the problem correlate to External Hard Resets with no WatchDog timers? (If so, this
indicates a loss of power. Correct your power problem.)
o is intermittent connectivity indicated? (If so, verify your configuration, power level, cables
and connections and the speed duplex of both ends of the link).
o does the problem correlate to loss-of-sync events?
• Are connections made via shielded cables?
• Does the GPS antenna have an unobstructed view of the entire horizon?
• Has the site grounding been verified?
Chapter 11: Troubleshooting General troubleshooting procedure
Page 11-25
Secondary Steps
After preliminary fault isolation is completed through the above steps, follow these:
• Check the Canopy knowledge base (https://support.cambiumnetworks.com/forum) to find
whether other network operators have encountered a similar problem.
• Proceed to any appropriate set of diagnostic steps. These are organized as follows:
o Module has lost or does not establish connectivity on page 11-26
o NAT/DHCP-configured SM has lost or does not establish connectivity on page 11-28
o SM Does Not Register to an AP on page 11-30
o Module has lost or does not gain sync on page 11-31
o Module does not establish Ethernet connectivity on page 11-32
o CMM4 does not pass proper GPS sync to connected modules on page 11-33
o Module Software Cannot be Upgraded on page 11-34
o Module Functions Properly, Except Web Interface Became Inaccessible on page 11-34

Module has lost or does not establish connectivity
To troubleshoot a loss of connectivity, perform the following steps:
Procedure 34
Troubleshooting loss of connectivity
1
Isolate the end user/SM from peripheral equipment and variables such as routers,
switches and firewalls.
2
Set up the minimal amount of equipment.
3
On each end of the link:
• Check the cables and connections.
• Verify that the cable/connection scheme—straight-through or crossover—is
correct.
• Verify that the LED labeled LNK is green.
• Access the General Status tab in the Home page of the module.
• Verify that the SM is registered.
• Verify that Received Power Level is -87 dBm or higher.
• Access the IP tab in the Configuration page of the module.
• Verify that IP addresses match and are in the same subnet.
• If RADIUS authentication is configured, ensure that the RADIUS server is
operational
Chapter 11: Troubleshooting Troubleshooting procedures
Page 11-27
4
On the SM end of the link:
• Verify that the PC that is connected to the SM is correctly configured to obtain an
IP address through DHCP.
• Execute
ipconfig
(Windows) or
ifconfig
(linux)
• Verify that the PC has an assigned IP address.
5
On each end of the link:
• Access the
General
tab in the Configuration page of each module.
• Verify that the setting for
Link Speeds
(or negotiation) matches that of the other
module.
• Access the
Radio
tab in the Configuration page of each module.
• Verify that the
Radio Frequency Carrier
setting is checked in the Custom Radio
Frequency Scan Selection List.
• Verify that the
Color Code
setting matches that of the other module.
• Access the browser LAN settings (for example, at
Tools > Internet Options > Connections > LAN Settings
in Internet Explorer).
• Verify that none of the settings are selected.
• Access the
Link Capacity Test
tab in the Tools page of the module.
• Perform a link test
• Verify that the link test results show efficiency greater than 90% in both the
uplink and downlink
• Execute
ping
.
o Verify that no packet loss was experienced.
o Verify that response times are not significantly greater than
4 ms from AP to SM
15 ms from SM to AP
o Replace any cables that you suspect may be causing the problem.
Note
A ping size larger than 1494 Bytes to a module times out and fails.
However, a ping of this size or larger to a system that is behind a
Canopy module typically succeeds. It is generally advisable to ping
such a system, since Canopy handles that ping with the same priority
as is given all other transport traffic. The results are unaffected by ping
size and by the load on the Canopy module that brokers this traffic.
6
After connectivity has been re-established, reinstall network elements and variables
that you removed in Step 1.
Chapter 11: Troubleshooting Troubleshooting procedures
Page 11-28
NAT/DHCP-configured SM has lost or does not establish
connectivity
Before troubleshooting this problem, identify the NAT/DHCP configuration from the following list:
• NAT with DHCP Client (
DHCP
selected as the
Connection Type
of the WAN interface) and DHCP
Server
• NAT with DHCP Client (
DHCP
selected as the
Connection Type
of the WAN interface)
• NAT with DHCP Server
• NAT without DHCP
To troubleshoot a loss of connectivity for a SM configured for NAT/DHCP, perform the following
steps.
Chapter 11: Troubleshooting Troubleshooting procedures
Page 11-29
Procedure 35
Troubleshooting loss of connectivity for NAT/DHCP-configured SM
1
Isolate the end user/SM from peripheral equipment and variables such as routers,
switches and firewalls.
2
Set up the minimal amount of equipment.
3
On each end of the link:
• Check the cables and connections.
• Verify that the cable/connection scheme—straight-through or crossover—is
correct.
• Verify that the LED labeled LNK is green.
4
At the SM:
• Access the NAT Table tab in the Logs web page.
• Verify that the correct NAT translations are listed.
RESULT: NAT is eliminated as a possible cause if these translations are correct.
5
If this SM is configured for NAT with DHCP, then at the SM:
• Execute ipconfig (Windows) or ifconfig (Linux)
• Verify that the PC has an assigned IP address.
• If the PC does not have an assigned IP address, then
o enter ipconfig /release “Adapter Name”.
o enter ipconfig /renew “Adapter Name”.
o reboot the PC.
o after the PC has completed rebooting, execute ipconfig
o if the PC has an assigned IP address, then
o access the NAT DHCP Statistics tab in the Statistics web page of the SM.
o

that you removed in Step 1.
Chapter 11: Troubleshooting Troubleshooting procedures
Page 11-30
SM Does Not Register to an AP
To troubleshoot a SM failing to register to an AP, perform the following steps.
Procedure 36
Troubleshooting SM failing to register to an AP
1
Access the Radio tab in the Configuration page of the SM.
2
Note the
Color Code
of the SM.
3
Access the Radio tab in the Configuration page of the AP.
4
Verify that the
Color Code
of the AP matches that of the SM.
5
Note the
Radio Frequency Carrier
of the AP.
6
Verify that the value of the
RF Frequency Carrier
of the AP is selected in the
Custom
Radio Frequency Scan Selection List
parameter in the SM.
7
In the AP, verify that the
Max Range
parameter is set to a distance slightly greater
than the distance between the AP and the furthest SM that must register to this AP.
8
Verify that no obstruction significantly penetrates the Fresnel zone of the attempted
link.
9
Access the
General Status
tab in the Home page of each module.
10
Remove the bottom cover of the SM to expose the LEDs.
11
Power cycle the SM.
RESULT:
Approximately 25 seconds after the power cycle, the green LED labeled
LNK must light to indicate that the link has been established. If the orange LED
labeled SYN is lit instead, then the SM is in Alignment mode because the SM failed
to establish the link.
12
If the AP is configured to require authentication, ensure proper configuration of
RADIUS or Pre-shared AP key.
13
In this latter case and if the SM has encountered no customer-inflicted damage,
then request an RMA for the SM.
Chapter 11: Troubleshooting Troubleshooting procedures
Page 11-31
Module has lost or does not gain sync
To troubleshoot a loss of sync, perform the following steps.
Procedure 37
Troubleshooting loss of sync
1
Access the Event Log tab in the Home page of the SM
2
Check for messages with the following format:
RcvFrmNum =
ExpFrmNum =
3
If these messages are present, check the Event Log tab of another SM that is
registered to the same AP for messages of the same type.
4
If the Event Log of this second SM does not contain these messages, then the fault
is isolated to the first SM.
If the Event Log page of this second SM contains these messages, access the GPS
Status page of the AP.
5
If the
Satellites Tracked
field in the GPS Status page of the AP indicates fewer than
4 or the
Pulse Status
field does not indicate Generating Sync, check the GPS Status
page of another AP in the same AP cluster for these indicators. GPS signal
acquisition must not take longer than 5 minutes from unit startup.
6
If these indicators are present in the second AP, then:
• Verify that the GPS antenna still has an unobstructed view of the entire horizon.
• Visually inspect the cable and connections between the GPS antenna and the
CMM4. If this cable is not shielded, replace the cable with shielded cable
7
If these indicators are not present in the second AP, visually inspect the cable and
connections between the CMM4 and the AP antenna. If this cable is not shielded,
replace the cable with shielded cable.

Module does not establish Ethernet connectivity
To troubleshoot a loss of Ethernet connectivity, perform the following steps:
Procedure 38
Troubleshooting loss of Ethernet connectivity
1
Verify that the connector crimps on the Ethernet cable are not loose.
2
Verify that the Ethernet cable is not damaged.
3
If the Ethernet cable connects the module to a network interface card (NIC), verify
that the cable is pinned out as a straight-through cable.
4
If the Ethernet cable connects the module to a hub, switch, or router, verify that the
cable is pinned out as a crossover cable.
5
Verify that the Ethernet port to which the cable connects the module is set to auto-
negotiate speed.
6
Verify VLAN configuration in the network, which may cause loss of module access
if the accessing device is on a separate VLAN from the radio.
7
Power cycle the module.
RESULT:
Approximately 25 seconds after the power cycle, the green LED labeled
LNK must light up to indicate that the link has been established. If the orange LED
labeled SYN is lit instead, then the module is in Alignment mode because the
module failed to establish the link.
8
In this latter case and if the module has encountered no customer-inflicted damage,
then request an RMA for the module.
Chapter 11: Troubleshooting Troubleshooting procedures
Page 11-33
CMM4 does not pass proper GPS sync to connected modules
If the Event Log tabs in all connected modules contain Loss of GPS Sync Pulse messages, perform
the following steps.
Procedure 39
Troubleshooting CMM4 not passing sync
1
Verify that the GPS antenna has an unobstructed view of the entire horizon.
2
Verify that the GPS coaxial cable meets specifications.
3
Verify that the GPS sync cable meets specifications for wiring and length.
4
If the web pages of connected modules indicate any of the following, then find and
eliminate the source of noise that is being coupled into the GPS sync cable:
• In the GPS Status page:
o anomalous number of
Satellites Tracked
(greater than 12, for example)
o incorrect reported
Latitude
and/or
Longitude
of the antenna
• In the Event Log page:
o garbled GPS messages
o large number of Acquired GPS Sync Pulse messages
GPS signal acquisition must not take longer than 5 minutes from unit startup.
5
If these efforts fail to resolve the problem, then request an RMA for the CMM4.
