During certain failure conditions, including out-of-range conditions, an error message
will display on the OCP panel and a corresponding error code will sound from the
server’s speaker.

located below the OCP once after a beep sounds. To enable it,
repress the button once.
Hot keys are defined in BIOS as [CTRL] + [ALT] +[1] and enable toggling of the OCP
display status messages just as though the OCP button were pressed.
NOTE:
Hot keys do not work during POST or during host server
request service from the OCP.

You can examine the server status messages by pressing the OCP switch located
on the front panel repeatedly to sequence through the status list. The OCP switch is
disabled during POST, during host request service from the 8031, or if an error is
detected. The following table lists and describes the status messages and the error
messages that display on the server’s OCP panel. Also included are possible actions
to take if a problem persists.
