v Follow the suggested actions in the order in which they are listed in the Action column until the problem

service technician.

Symptom Action
The server resets (restarts)
occasionally.
1. If the reset occurs during POST and the POST watchdog timer is enabled (click
System Settings --> Integrated Management Module --> POST Watchdog
Timer
in the Setup utility to see the POST watchdog setting), make sure that
sufficient time is allowed in the watchdog timeout value ( POST Watchdog
Timer ). If the server continues to reset during POST, see “POST” on page 18
and “Diagnostic programs and messages” on page 190.
2. If the reset occurs after the operating system starts, disable any automatic
server restart (ASR) utilities, such as the IBM Automatic Server Restart IPMI
Application for Windows, or any ASR devices that are be installed.
Note: ASR utilities operate as operating-system utilities and are related to the
IPMI device driver. If the reset continues to occur after the operating system
starts, the operating system might have a problem; see “Software problems” on
page 187.
3. If neither condition applies, check the system-error log or IMM2 system-event
log (see “Event logs” on page 16).
