Symptom Action
The server resets (restarts)
occasionally
1.
If the reset occurs during POST and the POST watchdog timer is enabled (click
Advanced Setup > Baseboard Management Controller (BMC) Setting > BMC
Post Watchdog in the Configuration/Setup Utility program to see the POST
watchdog setting), make sure that sufficient time is allowed in the watchdog
timeout value (BMC POST Watchdog Timeout). See the User’s Guide for
information about the settings in the Configuration/Setup Utility program.
If the server continues to reset during POST, see the POST and diagnostic
programs informations in the x3650 Problem Determination and Service Guide .
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 ASR devices that may 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.
3. If neither condition applies, check the system event/error log or BMC system
event log. Refer to the error log information in the x3650 Problem Determination
and Service Guide .
