Light Path Diagnostics Leds - IBM x3690 X5 Service Manual

Light path diagnostics LEDs

The following table describes the LEDs on the light path diagnostics panel and
suggested actions to correct the detected problems. For additional information, see
"Server controls, LEDs, and power" on page 11 and the "System-board LEDs" on
page 23 for the location of the system board LEDs.
Note: Check the IMM system-event log or system event log for additional
information before replacing a FRU.

v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v See Chapter 3, "Parts listing", in the Problem Determination and Service Guide to determine which components
are customer replaceable units (CRU) and which components are field replaceable units (FRU).
v If a action step is preceded by "(Trained service technician only)," that step must be performed only by a
trained service technician.

Action
Use the Setup utility to check the system event log for
information about the error (see "Using the Setup utility" on
page 402).
If the OVER SPEC LED is lit, use one of the following
procedures:
1. Turn off the server, disconnect the power from the server,
and install additional power supplies. Two power
supplies are needed for a fully configured server in
non-redundant mode. Four power supplies are required
to support fully loaded, redundant operation.
2. Remove any recently installed options.
3. Restart the server to see whether the problem remains.
Check the IMM system event log and the system-event log
for information about the error. Replace any components that
are identified in the error logs.
1. Check the QPI expansion port link LEDs on the server to
identify the failed port or cable (LED is below and to the
side of the rear QPI ports).
2. Check the EXA port link LEDs on the MAX5 (if attached)
to identify the failed port or cable.
3. Reseat the cable.
4. Replace the cable.
1. Check the power-supply in the server and the MAX5 that
has an lit amber LED (see "Power-supply LEDs" on page
78).
2. Make sure that the power supplies are seated correctly.
3. Remove one of the power supplies to isolate the failed
power supply.
4. Replace the failed power supply.
