System runs, then goes down
Troubleshooting when
the system goes down
while running
If a system runs normally and then goes down for no apparent
reason, follow these steps.
Step Action
1 Check the SEER printouts.
Note: If the system prints more than one SEER, it
may indicate a combination of problems. If the
system goes down as a result of an Enhanced
MMP40 or MMP40 CPU card problem, the SEERs
will indicate an OS program crash.
2 Power the system off, wait about 90 seconds, then
power on again.
3 Observe the diagnostic messages from BootROM
on the administration terminal.
4 If the diagnostic messages indicate hardware faults,
follow the board replacement sequence
corresponding with the failed diagnostics in “System
fails to start completely” on page 14-16.
5 If the system restarts with no hardware faults but
remains out of service, refer to the SEERs to identify
operational problems.
