Solving shared keyboard problems
Problems with BladeCenter shared resources might appear to be in the blade
server, but might actually be a problem in a BladeCenter unit keyboard
component.
To check the general function of shared BladeCenter keyboard resources, perform
the following procedure.
1. Verify that the keyboard/video select button LED on the front of the blade
server is lit.
A lit indicator shows that the blade server is connected to the shared keyboard.
2. Verify that the keyboard cable is securely connected to the active BladeCenter
management module.
3. Verify that the keyboard works with another blade server.
4. Verify that the management module is operating correctly.
See the documentation for your BladeCenter unit.
Some BladeCenter unit types have several management-module components
that you might test or replace.
See the online information or the
Installation Guide for your management
module for more information.
5.
Replace the keyboard.
6. Replace the management module.
See the online information center or the
Problem Determination and Service Guide
or the Hardware Maintenance Manual and Troubleshooting Guide for your
BladeCenter unit.
If these steps do not resolve the problem, it is likely a problem with the blade
server. See “Keyboard problems” on page 196 for more information.
Solving shared media tray problems
Problems with BladeCenter shared resources might appear to be in the blade
server, but might actually be a problem in a BladeCenter unit media tray
component.
