POST beep codes

In addition to the beep codes that are described in "POST beep code descriptions" on
page 17, your server might emit beep codes that are described in the following table.
For example, a 1-2-4 beep code sounds like one beep, a pause, two consecutive
beeps, another pause, and four more consecutive beeps.

xSeries 440:Troubleshooting Guide
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.
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.
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.
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.
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.
