31.5.4 BHS Does Not Register to a BHM
To troubleshoot an BHS failing to register to a BHM, perform the following steps.
Procedure 51: Troubleshooting BHS failing to register to a BHM
1. Access the Configuration page of the BHS.
2. Note the Color Code of the BHS.
3. Access the Configuration page of the BHM.
4. Verify that the Color Code of the BHM matches that of the BHS.
5. Note the RF Frequency Carrier of the BHM.
6. Verify that the value of the RF Frequency Carrier of the BHM is selected in the
Custom RF Frequency Scan Selection List parameter on the Configuration
page of the BHS.
7. Verify that a clear line of sight exists between the AP and the SM, and that no
obstruction significantly penetrates the Fresnel zone of the attempted link.
8. Verify that both the BHM and BHS are of the same frequency band range and
encryption (for example, 5200BH and 5200BH).
9. Remove the bottom cover of the BHS to expose the LEDs.
10. Power cycle the SM.
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 SM is in Alignment mode
because the SM failed to establish the link. In this latter case, and if the SM has
encountered no customer-inflicted damage, then request an RMA for the SM.

31.5.5 Module Has Lost or Does Not Gain Sync
To troubleshoot a loss of sync, perform the following steps.
Procedure 52: Troubleshooting loss of sync
1. Access the Event Log page of the SM.
2. Check for messages with the following format:
RcvFrmNum =
ExpFrmNum =
(See Table 60: Event Log messages for abnormal events on Page 332.)
3. If these messages are present, check the Event Log page 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.
