Chapter 7: Troubleshooting
Monitor
Your server has no video and the LED on the control panel indicates that the system is
in reset mode
■
Make sure that all the cables, processors, and VRMs are fully seated.
■
Possibly a faulty VRM. Replace the VRM(s).
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.
■
Check the memory boards for fault LEDs. Replace faulty DIMMs.
■
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 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
