Symptom
Action
Monitor or video not available
or displays blank/distorted
images.
1. Make sure that the monitor cables are firmly connected.
2. If the server is attached to a KVM switch, bypass the KVM switch to eliminate it
as a possible cause of the problem; connect the monitor cable to the correct
connector on the rear of the server. If the video now works, replace the KVM
switch.
3. Replace the standard I/O book.
The monitor works when you
turn on the server, but the
screen goes blank when you
start some application
programs.
1. Make sure that:
• The application program is not setting a display mode that is higher than the
capability of the monitor.
• You installed the necessary device drivers for the application.
• The application requirements for the video are compatible with the video
capabilities of the server.
Wrong characters appear on
the screen.
1. Verify that the language and locality settings are correct for the keyboard and
operating system.
2. If the wrong language is displayed, update the server firmware to the latest level
(see “Updating the firmware ” on page 119) with the correct language.
3. Reseat the monitor cable.
