Reading the Operator Panel Display
The operator panel display is located in the media drawer of the pSeries 690 and is
used to:
v Track the progress of the system unit self tests and configuration program
v Display codes when the operating system comes to an abnormal end
v Display system messages
Checkpoints
During power-on self-test (POST), four-digit checkpoints display, indicating the progress
of the testing. If an error is detected that requires attention, the server halts with an
eight-digit error code displayed in the upper row of the operator panel display, starting
in the leftmost position. This eight-digit error code identifies the error. For a listing of the
error codes, see the Eserver

The four-digit checkpoints are in the form of nnnn, where n is an alphabetic or numeric
character.
