2.14.1 Solving shared keyboard problems
Problems with shared resources might appear to be in the blade server, but might actually
be a problem in a Bull Blade Chassis - Enterprise keyboard component.
To check the general function of shared 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 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 Bull Blade Chassis - Enterprise.
Some Bull Blade Chassis - Enterprise types have several management-module
components that you might test or replace.
See the
Installation Guide for your management module for more information.
5. Replace the keyboard.
6. Replace the management module.
See the
Problem Determination and Service Guide or the Hardware Maintenance
Manual and Troubleshooting Guide for your Bull Blade Chassis - Enterprise.
If these steps do not resolve the problem, it is likely a problem with the blade server. See
“ Keyboard problems ” on page 159 for more information.
