Keyboard or mouse device not working
Use this procedure if a keyboard, mouse, or pointing device is not working.
Problem
A keyboard, mouse or pointing device no longer works.
Investigation
Perform these steps to resolve the problem:
1. Verify that the device is connected to the advanced management module.
2. Verify that the KVM is owned by the blade server.
Tip: On a keyboard that is directly attached to the advanced management
module, you can press keyboard keys in the following sequence to switch KVM
control between blade servers:
NumLock NumLock blade_server_number Enter
Where blade_server_number is the two-digit number for the blade bay in which
the blade server is installed. If you press NumLock twice and then do not enter
a blade server bay, the keyboard may appear to be locked. In this case, either
enter a blade server bay number or press Enter.
3. Reseat the device cable.
4. Replace the device.
Keyboard or mouse device not working after KVM ownership
change
Use this procedure if a keyboard, mouse, or pointing device stops working after
you switch the KVM to another blade server.
Problem
You attempted to change the ownership of the KVM to a different blade server,
and the keyboard, mouse or pointing device no longer works.
