Monitor
Your server is running but there is no picture
■
Adjust the brightness and contrast controls to the center position.
■
Make sure that the monitor is plugged in and turned on. If the monitor is
turned on, the power LED should be lit.
■
Check the port and cable for bent or damaged pins.
■
Connect your monitor to another computer, or connect a monitor that you
know works to your server.
The color is not uniform
Make sure that the monitor warms up for at least 30 minutes before making a
final judgment about color uniformity.
Make sure that:
■
The monitor is not positioned too close to another monitor, electric fan,
or fluorescent light.
■
You demagnetize the screen using the monitor’s degauss feature. For
more information on degauss, see the monitor’s documentation.
A horizontal line or wire is visible across the CRT monitor screen
The monitor may use thin damper wires, located approximately 1/3 of the way
from the upper and lower screen edges, to stabilize the internal aperture grille.
These wires are most obvious when the monitor displays a white background.
The aperture grille allows more light to pass through the screen for brighter
colors and greater luminescence. The damper wire is a critical part of the overall
monitor design and does not negatively affect the monitor’s function.
Power
You press the power button, but the server does not turn on
■
If the power button LED is green, the server is turned on, but you may not
be seeing an image on the monitor. For monitor troubleshooting, see
“Monitor” on page 85 .
■
If your server is plugged into a surge protector or UPS, make sure that the
surge protector or UPS is connected securely to an electrical outlet, turned
on, and working correctly. One way to check this is to plug the server
directly into a wall outlet, bypassing the surge protector or UPS.
■
Make sure that the electrical outlet is working by plugging a working
device, such as a lamp, into the outlet, then turning it on to test the outlet.
■
Open your server and make sure that the power supply module cage cable
is connected correctly to the system board.
When you turn on the server, it makes several short beeps
■
The short beeps indicate the server has encountered some type of error.

“Beep codes” on page 75 .
