ERROR MESSAGES

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

Test). When the POST detects any error, it displays an error message and its error code on the
display unit.

failure, use of the keyboard or mouse at the following events causes POST to assume a keyboard
controller error and stop processing.

!
Immediately after the system is rebooted in response to a keyboard instruction
!
(simultaneous key entry of Ctrl + Alt + Delete)
