Troubleshooting 8-3
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 SCSI Configuration Utility
appears on the screen following the server reboot.
IMPORTANT:
Take a note on the on-screen message before contacting your service
representative. The alarm indication would be a great help for maintenance.
