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.
5. If the Event Log page of this second SM contains these messages, access the
GPS Status page of the AP.
6. 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.
7. If these indicators are present in the second AP
a. verify that the GPS antenna still has an unobstructed view of the entire
horizon.
b. visually inspect the cable and connections between the GPS antenna and
the CMM.
c. if this cable is not shielded, replace the cable with shielded cable.
8. If these indicators are not present in the second AP
a. visually inspect the cable and connections between the CMM and the AP
antenna.
b. if this cable is not shielded, replace the cable with shielded cable.

To troubleshoot a loss of Ethernet connectivity, perform the following steps.
Procedure 53: 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. Power cycle the module.
RESULT: Approximately 25 seconds after the power cycle, the green LED
labeled LNK should light 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.
7. In this latter case, and if the module has encountered no customer-inflicted
damage, then request an RMA for the module.
