See Chapter 4, “Parts listing, System x3690 X5 Types 7147, 7148, 7149, and 7192,” on page 249 to determine
which components are customer replaceable units (CRU) and which components are field replaceable units
(FRU).
v
If an action step is preceded by “(Trained service technician only),” that step must be performed only by a
Trained 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 error codes”
on page 38 and “DSA messages” on page 82.
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 66.
3. If neither condition applies, check the event logs (see “Event logs” on page 35).
