Troubleshooting charts

You can use the troubleshooting charts in this section to find solutions to problems that have definite symptoms.

Note: The symptoms for monitor, keyboard, and mouse apply only to the devices connected to the management module; they do not apply to the remote console.

See the Hardware Maintenance Manual and Troubleshooting Guide on the IBM BladeCenter Documentation CD for more detailed information about testing the BladeCenter unit. If you have run the diagnostic test programs or if running the tests does not reveal the problem, call for service.

Attention: If diagnostic error messages appear that are not listed in the Hardware Maintenance Manual and Troubleshooting Guide, make sure that your BladeCenter unit has the latest level of firmware code installed.

If you have just added a new option and your system is not working, complete the following procedure before using the troubleshooting charts:

1.Remove the option that you just added.

2.Run the diagnostic tests to determine if your system is running correctly.

3.Reinstall the new device.

Monitor problems

Note: The monitor screen remains blank until directed to a blade server that is turned on; this is normal behavior.

Some IBM monitors have their own self-tests. If you suspect a problem with your monitor, see the information that comes with the monitor for instructions for testing and adjusting the monitor. If you cannot diagnose the problem, call for service.
