Note: When there is a reference to an error log in the following table and your
model has the optional Remote Supervisor Adapter II SlimLine option
installed, view the system event error log; otherwise, view the POST error
log.
The two error logs are located on the Configuration/Setup Utility in the
Event/Error logs option. For more information, see the User’s Guide .
LED Problem Action
None An error has occurred and cannot be
diagnosed, or the ASM processor has
failed. The error is not represented by a
Light Path diagnostics LED.
Check the system error log for information about the error.
OVER
SPEC
The power supplies are using more
power than their maximum rating.
Replace the failing power supply, or remove optional devices
from the server.
PS 1 When the LED is lit, the power supply
in bay 1 has failed. When the LED
flashes, an invalid power-supply
configuration has occurred.
If the power supply has failed, call for service. If a configuration
error has occurred, make sure that the power supply is installed
correctly.
PS 2 When the LED is lit, the power supply
in bay 2 has failed. When the LED
flashes, an invalid power-supply
configuration has occurred.
If the power supply has failed, call for service. If a configuration
error has occurred, make sure that the power supply is installed
correctly.
CPU When the LED is lit, a microprocessor
has failed. When the LED flashes, an
invalid microprocessor configuration
has occurred.
If a lit LED on the system board indicates a problem with a
microprocessor, make sure that the microprocessor is installed
correctly. See the Option Installation Guide on the IBM xSeries
Documentation CD for information about installing a
microprocessor.
If the problem remains, call for service.
If a configuration error has occurred, make sure that the
microprocessors have the same cache size and type, and the
same clock speed. Microprocessor internal and external clock
frequencies must be identical.
VRM When the LED is lit, an error occurred
on the microprocessor voltage regulator
module (VRM). When the LED flashes,
an invalid VRM configuration has
occurred.
Replace the VRM. If the problem remains, call for service.
If a configuration error has occurred, make sure that the VRM is
installed correctly. If the problem remains, replace the VRM.
CNFG When the LED flashes, a hardware
configuration error has occurred.
Check the system error log for information about the error. The
Light Path diagnostic LED for the component that is causing the
configuration error also flashes.
MEM When the LED is on, a memory error
has occurred. When the LED flashes,
an invalid DIMM configuration has
occurred.
Replace the failing DIMM, which is indicated by the lit LED on
the system board. If a configuration error has occurred, make
sure the DIMMs are installed correctly.
NMI A machine check error has occurred. Check the system error log for information about the error.
S ERR A soft error has occurred. Check the system error log for information about the error.
SP The service processor has failed. Remove ac power from the server; then, reconnect the server
to ac power and restart the server.
If the problem remains, call for service.
DASD A hard disk drive error has occurred. Check the LEDs on the hard disk drives and replace the
indicated drive.
