Demand test descriptions and error codes - Avaya Support

SNC-BD (Switch Node Clock Circuit Pack)
h. Error Type 1281: the firmware detected problems with the interface used to track the status
of both SNCs when there are duplicated SNCs in a switch node carrier. Software may have
incorrect information for which SNC is active.
If the switch node carrier has only one SNC, replace the SNC.
If the switch node carrier has duplicate SNCs:
1. Replace the SNC that does not have its yellow LED lit.
2. Retry test board. Use display errors to check the error log. If the error is still in
the error log, replace the SNC that has its yellow LED lit.
i. Error Type 1537: loss of signal from the SNC on-board Stratum-3 oscillator detected by the
firmware. Replace the SNC circuit pack.
j. Error Type 1793: firmware detects failure of the phase-locked loop, inability to lock, or
failure of the clock drivers. The problem is on-board. Replace the SNC circuit pack. If the
error persists, follow normal escalation procedures.
k. Error Type 2049: firmware detects problems with the microcontroller used for Timing
Priority Number processing. Replace the SNC circuit pack.
l. Error Type 6008: There is a status mismatch between software and firmware. This is a
status indication and not a real problem. There is no repair action. Test #781 is not a
demand test.
