Light Path Diagnostics Leds - IBM System x3650 Type 7979 Problem Determination And Service Manual

press the remind button, you acknowledge the error but indicate that you will not
take immediate action. The system-error LED flashes while it is in Remind mode
and stays in Remind mode until one of the following conditions occurs:
v All known errors are corrected.
v The server is restarted.
v A new error occurs, causing the system-error LED to be lit again.

Light path diagnostics LEDs

The following table describes the LEDs on the light path diagnostics panel and
suggested actions to correct the detected problems.
Note: Check the system event/error log and BMC system event log for additional
information before replacing a FRU.
LED Problem
None, but An error has occurred and cannot be
the diagnosed, or the Advanced System
System Management (ASM) processor on the
Error LED Remote Supervisor Adapter II SlimLine
is lit. has failed. The error is not represented
by a light path diagnostics LED.
OVER The power supplies are using more
SPEC power than their maximum rating.
PS 1 The power supply in bay 1 has failed.
PS 2 The power supply in bay 2 has failed.
CPU A microprocessor has failed.
VRM An error occurred on the
microprocessor voltage regulator
module (VRM).
CNFG A hardware configuration error has
occurred.
MEM When this LED is lit, a memory error
has occurred.
NMI A machine check error has occurred.
S ERR Reserved.

Action
Check the system error log for information about the error.
Replace the failing power supply, or remove optional devices
from the server.
Make sure that the power supply is correctly seated. If the
problem remains, replace the failed power supply.
Make sure that the power supply is correctly seated. If the
problem remains, replace the failed power supply.
Make sure that the failing microprocessor, which is indicated by
a lit LED on the system board, is installed correctly. See
"Installing a microprocessor" on page 135 for information about
installing a microprocessor.
If the problem remains, replace the microprocessor (trained
service technician only).
Replace the VRM. If the problem remains, replace the system
board (trained service technician only).
Check the microprocessors just installed to be sure that they
are compatible with each other and with the VRM (see the
microprocessor section of the User's Guide for compatiblity
requirements). Replace an incompatible microprocessor.
Check the system error logs for information about the error.
Replace any components indicated.
Replace the failing DIMM, which is indicated by the lit LED on
the system board.
Check the system error log for information about the error.
