Action
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
v (Trained technician only) System board
2. Check the system-error log for information about the error.
3. Replace the failing component:
v Battery (see "Removing the battery" on page 273 and
"Installing the battery" on page 275).
v (Trained service technician only) System board (see
"Removing the system board" on page 290 and
"Installing the system board" on page 292).
1. If the CONFIG LED is not lit, complete the following steps
to correct the problem:
a. Check the LEDs on the hard disk drives for the drive
with a lit status LED and reseat the hard disk drive.
b. Reseat the hard disk drive backplane.
c. For more information, see "Hard disk drive problems"
on page 104.
d. If the error remains, replace the following components
one at a time, in the order listed, restarting the server
after each:
1) Replace the hard disk drive.
2) Replace the hard disk drive backplane.
e. If the problem remains, go to http://www.ibm.com/
