Troubleshooting Light path diagnostics - IBM BladeCenter (8677)

Troubleshooting


Problem

The following information may be used to find solutions to problems that have definite symptoms.

Resolving The Problem

The system-error LED on the system LED panel is lit when certain system errors occur. If the system-error LED on your BladeCenter unit is lit, use the following table to help determine the cause of the error and the action you should take.

BladeCenter system LED panel - Light Path Diagnostics table
Lit LED
Cause
Action
Location
A condition has occurred in this BladeCenter unit that has caused the remote system management to identify this BladeCenter unit as needing attention.
Look for any information or error LEDs on the system-LED panel, the modules, and the blades in the this BladeCenter unit, and follow the instructions in this table for those LEDs.
The system temperature has exceeded a threshold level.

1. Check to see if a blower module has failed. If it has, replace the blower module as soon as possible to regain redundancy.

2. Make sure the room temperature is not too high. (See “Features and specifications” on page 6 for temperature information.)

3. Check to see if a blade server has a temperature LED lit. If it has, see the documentation that comes with the blade server.

4. Make sure there is a blade, module, or filler plugged in each bay. If the problem remains, have the system serviced.

Information
A noncritical event has occurred that should be looked at, such as the wrong switch module inserted in a bay, or power needs that exceed the capacity of power modules currently installed.
Check the error log for the messages. Check the LEDs on the BladeCenter unit and the blade servers to isolate the component.
System error
A critical system error has occurred, such as non-redundancy on the power modules or a system error in a blade.
  1. Check the error log for messages.
  2. Look for an error LED on the modules and blades to locate the component.
    • If the error LED is on a module, follow the instructions for the module in this table.
    • If the error LED is on a blade, see the documentation that comes with the blade.
Management module
Management module errors
A critical error has occurred in the management module.
Unplug the management module and reinsert it, then, restart the BladeCenter unit. If the problem remains, replace the management module.
Management module Web interface to Ethernet switch module does not refresh
After adding or restarting an Ethernet switch module through the management-module Web interface, the Web page does not refresh. You will also be unable to connect to the Ethernet switch module through the Telnet interface.
You must wait until the Ethernet switch module completes POST. After Ethernet switch module POST is complete, you will be able to connect to the Ethernet switch module.
Power module
Power module error
A critical error has occurred in the power module.
Replace the module. If your BladeCenter unit has a redundant module for this power module, the BladeCenter unit continues to function using the redundant module.
Blower module
Blower-module error
The blower has failed or is operating too slowly.
Replace the blower module as soon as possible to regain cooling redundancy. The BladeCenter unit continues to function. The redundant blower module provides cooling to the BladeCenter unit and blades.
Switch module
Switch module error
A critical error has occurred in the switch module.
Replace the module.
