Intermittent problems
• Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
• See Chapter 7 “Parts listing, RS210 Types 6531, 6532, 6533, and 6534” on page 175 to determine which
components are customer replaceable units (CRU) and which components are field replaceable units (FRU).
• If an action step is preceded by “(Trained service technician only),” that step must be performed only by
a Trained service technician.
• Go to the Lenovo support Web site at to check for technical information,
hints, tips, and new device drivers or to submit a request for information.
Symptom
Action
A problem occurs only
occasionally and is difficult to
diagnose.
1. Make sure that:
• All cables and cords are connected securely to the rear of the server and
attached devices.
• When the server is turned on, air is flowing from the fan grille. If there is no
airflow, the fan is not working. This can cause the server to overheat and
shut down.
2. Check the system-error log or IMM system event log (see “POST” on page 19).
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 UEFI Setup Utility program 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 19.
2. If the reset occurs after the operating system starts, disable any automatic server
restart (ASR) utilities 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; see “Software problems”
on page 60.
3. If neither condition applies, check the system-error log or IMM system event
log (see “POST” on page 19).
If the problem remains, call for service.
