Page 4-10Procedure for SPE-Down Mode
4
The procedure to get a system out of SPE-Down mode follows.
NOTE:
This is important! If you cannot complete the first step or have problems
with the maintenance interface, then the first step should be to replace the
Processor circuit pack. In a high or critical reliability system the DUPINT-A
circuit pack can also cause SPE-Down.
1. If the alarms indicate a tape failure, replace the tape or tape drive and go
to Step 3. Otherwise, verify that there is a good tape in the tape drive. If a
tape is not present or if either the tape or tape drive is defective, then
restarting the system using the reset command causes the system to go
down again.
2. In a High or Critical Reliability system, select a carrier to repair first.
When it is possible to accurately determine the location of the problem,
use the display alarms [a | b ] command to display alarms for both SPEs
and check the red LEDs on the processor complex circuit packs. Select
the carrier where the red LEDs indicate the circuit pack alarmed. Bring up
the system on that carrier and then refer to Standby SPE Maintenance
documentation to repair the Standby SPE.
In a Standard Reliability system or after a carrier is chosen in a High or
Critical Reliability system, determine which circuit pack is defective by
displaying alarms and observing the red LEDs (as discussed previously).
Depending on the alarms, use Table 4-1
to replace the circuit packs
indicated, one by one, in the order shown.
