2049 FAIL The Standby SPE Maintenance/Tape Processor released the Standby SPE
processor with a request to perform the RAM Checksum Test on Standby
SPE Memory. The RAM checksum was correct; however, a significant
discrepancy was detected between two special Standby SPE Memory
locations that should contain the same time stamp value as the one
shadowed over from the Active SPE. This indicates that a problem exists
with one or more components that make up the Memory Shadowing Link
such that Active SPE Memory was not accurately shadowed to Standby
SPE Memory.
1. Check for both Active SPE and Standby SPE Common Shadow Circuit
errors and alarms. Refer to SHDW-CIR (Common Shadow Circuit)
Maintenance documentation and follow the prescribed procedures.
2. Check for Standby SPE Memory errors and alarms. Refer to MEM-BD
(Memory) Maintenance documentation and follow the prescribed
procedures.
3. Check the Inter-Carrier Cable to see if it is loose or disconnected. Also
if intermittent problems are occurring inspect the Inter-Carrier Cable for
cuts or broken leads. If so, follow the repair procedures for
reconnecting the Inter-Carrier Cable described in Chapter 6.
4. If all problems found in Steps 1, 2, or 3 have now been repaired,
proceed with Step 9. If no problems were found in Steps 1, 2, or 3,
proceed with Step 5.
5. Issue the display errors command and check to see if an Error Type
80 is logged against STBY-SPE. If so, the problem is the carrier A
Duplication Interface circuit pack. Replace the carrier A Duplication
Interface circuit pack as described in Chapter 6 and proceed with
Steps 9, 10, and 11.
6. Issue the display errors command and check to see if an Error Type
82 is logged against STBY-SPE. If so, the problem is the carrier B
Duplication Interface circuit pack. Replace the carrier B Duplication
Interface circuit pack as described in Chapter 6 and proceed with
Steps 9, 10, and 11.
7. Issue the display errors command and check to see if an Error Type
85 is logged against STBY-SPE. If so, the problem may be the Standby
SPE Memory circuit pack. Replace the Memory circuit pack as
described in Chapter 6 and proceed with Steps 9, 10, and 11.
