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.
