v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v See “Parts listing” to determine which components are customer replaceable units (CRU) and which
components are field replaceable units (FRU).
v If an action step is preceded by “(Trained service technician only)”, that step must be performed only by a
trained service technician.
LED Description Action
CPU An invalid microprocessor
configuration or a microprocessor
has failed (both the CPU LED
and the CNFG LED might be lit).
1. If the CNFG LED is lit, the system issues an invalid
microprocessor configuration error. Complete the
following steps to correct the problem:
a. Check the microprocessors that were just installed to
make sure that they are compatible with each other
and use the Setup utility and select System
Information > System Summary > Processor Details
to verify the microprocessors information.
b. (Trained service technician only) Replace the
incompatible microprocessor.
c. Check the system-error logs for information about the
error. Replace any components that are identified in
the error log.
2. If a microprocessor failure occurs, complete the following
steps:
a. (Trained service technician only) Make sure that the
failing microprocessor, which is indicated by a lit LED
on the system board, is installed correctly.

CALL.
VRM Reserved.
DASD 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”.
4. If the error remains, replace the following components 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 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.
6. If the problem remains, go to http://www.ibm.com/
