Troubleshooting
Monitor problems Action
The monitor works when
you turn on the system,
but goes blank after
some period of server
inactivity.
Ÿ
The system might have a screen-saver program, or
the network performance might be low. Move the
mouse.
Ÿ
The server might be set for energy savings with the
Advanced Power Management (APM) feature. This
feature is not available in your server and
therefore, has a default setting of Disabled. If the
APM feature setting has been enabled, change the
setting back to Disabled.
If the problem cannot be isolated and corrected, have
the system serviced.
The screen flickers. Set the monitor for the highest, noninterlaced refresh
rate supported by your monitor and the video
controller in your server. For additional information,
refer to the documentation that comes with your
monitor and the README files for the graphics
adapter (if applicable). The README files are on the
ServerGuide CDs that come with your server.
Attention:
Using a resolution or refresh rate that is not supported
by your monitor might damage it.
You can reset the refresh rate through your operating
system, using the instructions provided in the
README files. Refer to your operating system
documentation for further information on monitor
settings.
If this does not correct the problem, have the monitor
and system serviced.
Note: To reset the refresh rate, use a utility program,
such as AnyView Professional or WinMode.
