v If an action step is preceded by "(Trained technician only)," that step must be performed only by a trained
technician.
Symptom
All or some keys on the
keyboard do not work.
Action
1. If the reset occurs during POST and the POST watchdog timer is enabled (click
System Settings --> Integrated Management Module --> POST Watchdog
Timer in the Setup utility to see the POST watchdog setting), make sure that
sufficient time is allowed in the watchdog timeout value (POST Watchdog
Timer). If the server continues to reset during POST, see "POST error codes"
on page 122 and "DSA messages" on page 193.
2. If the reset occurs after the operating system starts, disable any automatic
server restart (ASR) utilities, such as the IBM Automatic Server Restart IPMI
Application for Windows, or any ASR devices that are be installed.
Note: ASR utilities operate as operating-system utilities and are related to the
IPMI device driver. If the reset continues to occur after the operating system
starts, the operating system might have a problem; see "Software problems" on
page 257.
3. If neither condition applies, check the event logs (see "Event logs" on page
115).
Action
1. Make sure that:
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 Setup utility and enable keyboardless
operation.
3. See http://www.ibm.com/systems/info/x86servers/serverproven/compat/
us/ for information about keyboard compatibility.
4. 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.
5. 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
