SHDW-LNK (Memory Shadowing Link)
Issue 4 May 2002 10-1507 555-233-123
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.
