LED Description Action
TEMP The system temperature has
exceeded a threshold level. A
failing fan can cause the TEMP
LED to be lit.
1. Make sure that the heat sink is seated correctly.
2. Determine whether a fan has failed. If it has, replace it.
3. Make sure that the room temperature is not too high. See
“Features and specifications” on page 6 for the server
temperature information.
4. Make sure that the air vents are not blocked.
5. Make sure that the heat sink, the fan on the adapter, or
the optional network adapter is seated correctly. If the fan
has failed, replace it.
6. If the failure remains, go to http://www.ibm.com/systems/

FAN A fan has failed, is operating too
slowly, or has been removed. The
TEMP LED might also be lit.
1. Reseat the failing fan, which is indicated by a lit LED near
the fan connector on the system board.
2. Replace the failing fan (see “Installing a hot-swap fan
assembly” on page 93).
BOARD An error has occurred on the
system board.
1. Check the LEDs on the system board to identify the
component that caused the error. The BOARD LED can
be lit due to any of the following reasons:
v
Battery

(Trained technician only) System board
2. Check the system-error log for information about the error.
3. Replace the failing component:

HDD A hard disk drive has failed or is
missing.
1. Check the LEDs on the hard disk drives for the drive with
a lit status LED and reseat the hard disk drive.
2. Reseat the hard disk drive backplane.
3. For more information, see the “Hard disk drive problems”
under the Troubleshooting tables in the Problem
Determination and Service Guide .
4. If the error remains, replace the following components one
at a time, in the order listed, restarting the server after
each:
a. Replace the hard disk drive.
b. Replace the hard disk drive backplane.
5. If the problem remains, go to http://www.ibm.com/systems/
