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 76.
• 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. See “Beep codes”
on page 67.
Processor
Your server does not recognize a new processor
• Make sure that the processor is fully seated in its socket. The processor should be
recognized automatically if it is installed correctly.
• If you have upgraded your server from one processor to two, you may need to reconfigure
your operating system so it recognizes the additional processor. For instructions, see your
operating system’s documentation.
