ERROR MESSAGES

If an error occurs in the server, an error message appears on the display unit connected to the server.

failure, use of the keyboard or mouse at times described in the list below causes the POST to
assume a keyboard controller error and stop processing.
Immediately after the server is powered
Immediately after the system is rebooted in response to a keyboard instruction
(simultaneous key entry of Ctrl + Alt + Delete)
Immediately after the system is rebooted in response to an OS instruction
During hardware initialization following restart of the POST

Do not make any keyboard entry or use the mouse before the memory count appears on
