The system power cord is plugged into the SBCE power module and a
working electrical outlet.
•
The monitor cables are connected properly.
•
The monitor is turned on and the Brightness and Contrast controls are
adjusted correctly.

Important
✏
In some memory configurations, the 3-3-3 beep code might sound during
POST followed by a blank display screen. If this occurs and the Boot
Fail Count feature in the Start Options of the Configuration/Setup Utility
program is set to Enabled (its default setting), you must restart the
computer three times to force the system BIOS to reset the CMOS
values to the default configuration (memory connector or bank of
connectors enabled).
2.
If you have verified these items and the screen remains blank, replace:
a.
Monitor
b.
Management module on the SBCE (see the SBCE Hardware Maintenance
Manual and Troubleshooting Guide).
Only the cursor appears.
•
Verify that the keyboard, video and mouse on the SBCE have not been
switched to another blade server. If the problem remains, see“Undetermined
problems” on page 100.
The monitor goes blank when
you direct it to a working blade
server, or goes blank when you
start some application
programs in the blade servers.
•
Verify that the monitor cable is connected to the video port on the SBCE
management module. Some monitors have their own self-tests. If you suspect a
problem with your monitor, see the information that comes with the monitor for
adjusting and testing instructions.
If you still cannot find the problem, try using the monitor with another blade
server. If the problem persists, see the Intel Server System SBCE Hardware
Maintenance Manual and Troubleshooting Guide on the Documentation CD.
