lit when a hard disk drive is
removed from the server.
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.
TEMP The system temperature has
exceeded a threshold level.
v Determine whether a fan has failed. If it has, replace
it.
v

If the problem remains, call for service.
FAN A fan has failed or is operating too
slowly. A failing fan can also cause
the TEMP LED to be lit.
Replace the failing fan, indicated by the lit LED.
CPU A microprocessor has failed. If a lit LED on the system board indicates a problem with
a microprocessor, make sure that the microprocessor is
installed correctly.
Replace the failing microprocessor.

pluggable VRM.
v
If the LED next to the integrated VRD is lit, replace
the system board.
PCI BUS An error has occurred on a PCI
bus.
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.
Replace the system board.
SERVICE
PROCESSOR BUS
The service processor has failed. Remove ac power from the server; then, reconnect the
