Post; Small Computer System Interface (Scsi) Messages - IBM eServer 200 xSeries User Reference Manual

POST

When you turn on the server, it performs a series of tests to check the operation of
system components and some of the options that are installed in the server. This
series of tests is called the power-on self-test, or POST.

2. A single problem might cause several error messages. When this occurs, work to
The possible types of beep codes that your system might emit are:
Repeating long beeps
