ERROR MESSAGES
If an error occurs in the server, an error message appears on the display unit connected to the server.
Error Messages after Power-on
Powering on the server automatically starts the self-diagnostic program, POST (Power On Self-
Test). When the POST detects any error, it displays an error message and its measure on the
display unit.
Follow the table below to troubleshoot such errors. However, even when there is no hardware
failure, use of the keyboard or mouse at the following timing 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
When the POST detects a hardware failure due to the above reason, restart the server once again.
If the same error message reappears, you may assume there is no hardware error. To ensure
normal operation of the server, however, make sure to follow the following restrictions.
„
Do not make any keyboard entry or use the mouse before the memory count appears on
the screen following the server power-on.
„
Do not make any keyboard entry or use the mouse before the start-up message of the
Configuration Utility appears on the screen following the server reboot.
IMPORTANT:
Take a note on the on-screen message before
contacting your sales agent. The alarm indication would be a great
help for maintenance.
