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.

problem remains, replace the monitor.
