v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v
See the parts listing in the x3650 Problem Determination and Service Guide 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 Problem Action
None, but
the
system-error
LED is lit.
An error has occurred and cannot be
diagnosed, or the Advanced System
Management (ASM) processor on the
Remote Supervisor Adapter II
SlimLine has failed. The error is not
represented by a light path
diagnostics LED.
Use the Configuration/Setup Utility program to check the
system-error log for information about the error.
OVER SPEC The power supplies are using more
power than their maximum rating.
1. Remove optional devices from the server.
2. Replace the failing power supply.
PS 1 The power supply in bay 1 has failed.
1.
Make sure the power supply is correctly seated and the
AC power cord is plugged in.
2. Replace the power supply.
PS 2 The power supply in bay 2 has failed.
1. Make sure the power supply is correctly seated.
2. Replace the power supply.
CPU A microprocessor has failed. Make sure that the failing microprocessor, which is indicated
by a lit LED on the system board, is installed correctly.
VRM An error occurred on the
microprocessor voltage regulator
module (VRM).
Replace the VRM.
CNFG A hardware configuration error has
occurred.
1. Check the microprocessors that were just installed to
make sure that they are compatible with each other and
with the VRM.
2. (Trained service technician only) Replace an incompatible
microprocessor.
3. Check the system error log for information about the
error. Replace any components that are indicated. (Use
the Configuration/Setup Utility program to view the
error logs.)
MEM A memory error has occurred. Replace the failing DIMM, which is indicated by the lit LED
on the system board.
NMI A machine check error has occurred. Check the system-error log for information about the error.
(Use the Configuration/Setup Utility program to view the
error logs.)
S ERR Reserved.
SP The service processor has failed.
1. Remove power from the server; then, reconnect the
server to power and restart the server.
2. Update the firmware on the BMC.
3. If a Remote Supervisor Adapter II SlimLine is installed,
update the firmware; if the problem remains, replace the
adapter.
DASD A hard disk drive error has occurred. Check the LEDs on the hard disk drives and replace the
indicated drive.
