Troubleshooting operational problems 15-3

System runs, then goes down

Standard 1.0 Option 11 EC Installation and Maintenance Guide November 1999

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.
