IBM® xSeries 250: User’s Reference
Repeating short beeps
The system board might contain a failing component, your keyboard might
be defective, or a key on the keyboard might be stuck. Ensure that:
1. Nothing is resting on the keyboard and pressing a key.
2. No key is stuck.
3. The keyboard cable is connected correctly to the keyboard and to the
correct connector on the server.
Running the diagnostic tests can isolate the server component that failed, but
you must have your system serviced. If the error message remains, call for
service.
Note: If you just connected a new mouse or other pointing device, turn off
the server and disconnect that device. Wait at least 5 seconds; then,
turn on the server. If the error message goes away, replace the device.
One long and one short beep
POST encountered an error on a video adapter. If you are using the integrated
video controller, call for service. If you are using an optional video adapter,
replace the failing video adapter.
One long and two short beeps
A video I/O adapter ROM is not readable, or the video subsystem is
defective. If you hear this beep combination twice, both the system board and
an optional video adapter have failed the test. This beep combination might
also indicate that the system board contains a failing component.
One long and three short beeps
The system-board video subsystem has not detected a monitor connection to
the server. Ensure that the monitor is connected to the server. If the problem
persists, replace the monitor.
Two long and two short beeps
POST does not support the optional video adapter. This beep combination
occurs when you install a video adapter that is incompatible with your server.
Replace the optional video adapter with one that the server supports or use
the integrated video controller.
