Symptom Action
All or some keys on the

1. If the server is attached to a KVM switch, bypass the KVM switch to eliminate it
as a possible cause of the problem: connect the keyboard cable directly to the
correct connector on the rear of the server.
2. See http://www.ibm.com/servers/eserver/serverproven/compat/us/ for keyboard
compatibility.
3. If you have installed a USB keyboard, run the Configuration/Setup Utility
program and enable keyboardless operation to prevent the POST error
message 301 from being displayed during startup.
4. If you are using a USB hub, disconnect the USB device from the hub and
connect it directly to the server.
5. Make sure that:
v The keyboard cable is securely connected to the server and the keyboard
and mouse cables are not reversed.
