1Run the Short Test Sequence first. If all tests pass, run the Long Test Sequence. Refer to the appropriate test description and follow the recommended procedures.

Notes:

• (a) Error Type 1 - The circuit pack stopped functioning or is physically removed from the system.

This alarm logs approximately 11 minutes after removing the circuit pack and/or the SAKI Sanity Test (#53) fails.

If the circuit pack is not in the system, insert a circuit pack in the same slot as the error indicates. See note (g).

• (b) Error Type 257 - Transient communication problems between the switch and this circuit pack. Execute the test board GGGVM command and refer to the repair procedures for the Control Channel Loop Around Test (#52).
• (c) Error Type 513 - On-board hardware failure. Aux data values correspond to the following detected errors:

  Aux Value	Detected Error
  4352	External RAM error
  4353	Internal RAM error
  4355	ROM Checksum error
  4357	Instruction set error

Reset the circuit pack with the busyout board GGGVM and reset board GGGVM commands. When reset, the circuit pack executes a set of tests to detect the presence of any of the faults listed above. Detection of one of these errors during initialization causes the circuit pack to lock-up and appear insane to the system. See the repair procedure in Note ().

• (d) Error Type 769 - The circuit pack detects a program logic error. While no action is required, this error can lead to other errors against this circuit pack.
• (e) 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.
• (f) Error Type 1291 - The MM720 BRI Media Module notifies maintenance software that it has detected a parity error while accessing its dynamic RAM (that stores the board's translation information and downloadable application firmware). Maintenance software resets the circuit pack.
• (g) 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.

• (h) Error Type 3840 - The circuit pack received an inconsistent down-link message (a bad header, port number, data, subqualifier, or logical link) over the Control Channel.
• (i) 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.

• (j) 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.
