LED
Problem
DASD/RAID
A hard disk drive, integrated SCSI
controller, or integrated RAID error
has occurred.This LED will also be
lit when a hard disk drive is
removed from the server.
TEMP
The system temperature has
exceeded a threshold level.
FAN
A fan has failed or is operating too
slowly. A failing fan can also cause
the TEMP LED to be lit.
CPU
A microprocessor has failed.
S_ERR
A soft error has occurred.
VRM
The VRM or integrated VRD has
failed.
PCI BUS
An error has occurred on a PCI
bus.
SERVICE
The service processor has failed.
PROCESSOR BUS
NMI
A machine check error has
occurred.
Note: The amber CONFIG LED is lit only when the Diagnostics Panel LED test is
performed by Enhanced Diagnostics.
Action
v Check the LEDs on the hard disk drives and replace
the indicated drive.
v Check the LEDs on the system board and replace the
indicated component.
v If a hard disk drive LED remains lit after being
replaced, call for service.
v Determine whether a fan has failed. If it has, replace
it.
v Make sure that the room temperature is not too high.
See "Features and specifications" on page 5 of the
Installation Guide for temperature information.
v Make sure that the air vents are not blocked.
If the problem remains, call for service.
Replace the failing fan, indicated by the lit LED.
If a lit LED on the system board indicates a problem with
a microprocessor, make sure that the microprocessor is
installed correctly.
If the problem remains, call for service.
1. Restart the server.
2. Update the firmware and adapter drivers.
3. Check the POST error log
If the problem remains, call for service.
v Remove ac power from the server, and then restart
the server.
v If the LED next to the VRM is lit, replace the
pluggable VRM.
v If the LED next to the integrated VRD is lit, call for
service.
v Check the system error log for information about the
error.
v If you cannot isolate the failing adapter through the
information in the system error log, remove one
adapter at a time from the failing PCI bus, and restart
the server after each adapter is removed.
If the problem remains, call for service.
Remove ac power from the server; then, reconnect the
server to ac power and restart the server.
If the problem remains, call for service.
Check the error log to diagnose the condition.
