•
Be sure no loose connections (on page 58 ) exist in the rest of the server, particularly with the cables
that connect to the system board.

Be sure no foreign material exists, such as screws, bits, or slot bracket blanks, that may be short
circuiting components.
External device problems
Video problems
Screen is blank for more than 60 seconds after you power up the server
Action :
1.
Power up the monitor and be sure the monitor light is on, indicating that the monitor is receiving
power.
2.
Be sure the monitor power cord is plugged into a working grounded (earthed) AC outlet.
3.
Be sure the monitor is cabled to the intended server or KVM connection.
4.
Be sure no loose connections (on page 58 ) exist.
o
For rack-mounted servers, check the cables to the KVM switch and be sure the switch is correctly
set for the server. You may need to connect the monitor directly to the server to be sure the KVM
switch has not failed.
o
For tower-model servers, check the cable connection from the monitor to the server, and then
from the server to the power outlet.
5.
Press any key, or type the password, and wait a few moments for the screen to activate to be sure
the energy saver feature is not in effect.
6.
Be sure the video driver is current. Refer to the third-party video adapter documentation for driver
requirements.
7.
Be sure a video expansion board has not been added to replace onboard video, making it seem like
the video is not working. Disconnect the video cable from the onboard video, and then reconnect it
to the video jack on the expansion board.
NOTE: All servers automatically bypass onboard video when a video expansion board is
present.
8.
Press any key, or type the password, and wait a few moments for the screen to activate to be sure
the power-on password feature is not in effect. You can also tell if the power-on password is enabled
if a key symbol is displayed on the screen when POST completes.
If you do not have access to the password, you must disable the power-on password by using the
Password Disable switch on the system board. Refer to the server documentation.
9.
If the video expansion board is installed in a PCI Hot Plug slot, be sure the slot has power by
checking the power LED on the slot, if applicable. Refer to the server documentation.
10.
Be sure the server and the operating system support the video expansion board.
Monitor does not function properly with energy saver features
