Action
1. Make sure that:
v All cables and cords are connected securely to the rear of the server and
attached devices.
v When the server is turned on, air is flowing from the fan grille. If there is no
airflow, the fan is not working. This can cause the server to overheat and
shut down.
2. Check the system event/error log (see "Error logs" on page 125).
3. See "Solving undetermined problems" on page 229.
Action
1. Make sure that:
v The keyboard is compatible with the server. See http://www.ibm.com/servers/
eserver/serverproven/compat/us/.
v The keyboard cable is securely connected.
v The server and the monitor are turned on.
2. If you are using a USB keyboard, run the Configuration/Setup Utility program
and enable keyboardless operation to prevent the 301 POST error message
from being displayed during startup.
3. If you are using a USB keyboard and it is connected to a USB hub, disconnect
the keyboard from the hub and connect it directly to the server.
4. Replace the following components one at a time, in the order shown, restarting
the server each time:
a. Keyboard
b. (Trained service technician only) System board
