Power-Supply Leds - IBM x3655 - System - 7985 Service Manual

LED Problem
SP The service processor has failed.
DASD A hard disk drive error has occurred.
BRD An error has occurred on the system
board.
FAN A fan has failed, is operating too slowly,
or has been removed. The TEMP LED
might also be lit.
TEMP The system temperature has exceeded
a threshold level. A failing fan can
cause the TEMP LED to be lit.
RAID A RAID controller error has occurred.
PCI An error has occurred on a PCI bus or
on the system board. An additional LED
will be lit next to a failing PCI slot.

Power-supply LEDs

The following minimum configuration is required for the DC LED on the power
supply to be lit:
v Power supply
v Power backplane
v Power cord
The following minimum configuration is required for the server to start:
v One microprocessor
v Two 512 MB DIMMs on the system board

Action
Remove ac power from the server; then, reconnect the server
to ac power and restart the server.
Update the firmware on the BMC.
If a Remote Supervisor Adapter II SlimLine is installed, update
the firmware; if the problem remains, replace the adapter.
If the problem remains, replace the system board (trained
service technician only).
Check the LEDs on the hard disk drives and replace the
indicated drive.
If the problem remains, replace the hard disk drive backplane
(trained service technician only).
v Check the LEDs on the system board to identify the
component that is causing the error.
v Check the system error log for information about the error.
Replace the failing fan, which is indicated by a lit LED on the
fan body.
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 4 for temperature
information.
v Make sure that the air vents are not blocked.
Check the system error log for information about the error.
v Check the LEDs on the PCI slots to identify the component
that is causing the error.
v Check the system error log for information about the error.
v If you cannot isolate the failing adapter through the LEDs
and 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, replace the following components, in
the order shown, restarting the server each time:
v PCI riser card
v (Trained service technician only) System board
