System Technician-Demanded Tests: Descriptions And Error Codes - Avaya G350 Maintenance Manual

•
Error Type 1025 – The circuit pack cannot update and read back NPE/NCE memory. This error
can be ignored, but may lead to other errors against this circuit pack.
•
Error Type 1291 – The MM720 and MM722 BRI Media Modules notify maintenance software
that they have detected a parity error while accessing their dynamic RAM (that stores the board's
translation information and downloadable application firmware). Maintenance software resets the
circuit pack.
•
Error Type 3586 – The SPE software detects an excessive number of up-link messages from the
TN2185 board within a certain time period. To prevent the faulty board from flooding the switch
with data, the switch software takes the board out of service and alarms it. The switch software
also tells the Archangel to ignore up-link messages from the board.
When the board is alarmed due to this error, the switch software periodically puts the board back
in service and tells the Archangel to process up-link messages from the board. If the problem still
exists, the software takes the circuit pack out of service again. If the circuit pack does not exhibit
the problem for a certain time period, then maintenance software resolves the alarm and the
circuit pack is left in service.
•
Error Type 3840 – The circuit pack received an inconsistent down-link message (a bad header,
port number, data, sub-qualifier, or logical link) over the Control Channel.
•
Error Type 3842 – The board is receiving data from the bus faster than it can distribute the data to
its endpoints, causing the FIFO RAM buffer to overflow. This error can occur occasionally due to
the statistical sizing of the buffers. If it occurs frequently, it may indicate a LAPD parameter
mismatch. LAPD should recover from this problem, but it may degrade the performance of the
LAN bus.
When this error is reported, maintenance reads and clears the board counter and logs the problem
in the maintenance error log.
•
Error Type 3843 – Bad translation RAM detected, but the call continues by using another
translation location. The circuit pack reports this error when it cannot update NPE/NCE memory
and read it back. This error is not service-affecting and can be ignored, but can lead to other types
of errors against this circuit pack.
System Technician-Demanded Tests:
Descriptions and Error Codes
When inspecting errors in the system, always investigate tests in the order listed below. By clearing error
codes associated with the Control Channel Loop Around Test, for example, you may also clear errors
generated from other tests in the testing sequence.
