(cont’d.)
FAIL 5. Issue the refresh spe-standby command to put the Standby
SPE in Standby Mode. This command may have to be issued
multiple times. If the refresh spe-standby command
successfully completes 5 times without the Standby SPE
becoming labeled “standby” on the status system form, wait
20 minutes. This does not include cases where the command
completes with the terminal message line errors “Refresh not
successful; use ‘display errors’ to check for STBY-SPE
errors” or “Cannot interrupt Standby SPE while entering
maintenance mode; please try later.” Issue the refresh
spe-standby command once more.
6. Repeat the test.
7. Issue the test spe-standby long command to thoroughly
test all Standby SPE components.
2048 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 and the RAM
checksum was determined to be incorrect.
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. 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.
