No characters appear on screen
Check the following:
Is the keyboard working? Check to see that the "Num Lock" light is functioning.
Is the video monitor plugged in and turned on? Many modern video monitors shut down
when inactive and may require a moment to warm up when activated.
Are the brightness and contrast controls on the video monitor properly adjusted?
Are the video monitor switch settings correct?
Is the video monitor signal cable properly installed?
Is the onboard video controller enabled?
If you are using an add-in video controller board, do the following:
1.
Verify that the video controller board is fully seated in the baseboard connector (and verify
that the video monitor is plugged in to the ACTIVE video controller).
2.
Reboot the system for changes to take effect.
3.
If there are still no characters on the screen after you reboot the system and POST emits a
beep code, write down the beep code you hear. This information is useful for your service
representative. See 'Error and informational messages' which start on page 7 of this chapter.
4.
If you do not receive a beep code and characters do not appear, the video display monitor or
video controller may have failed. You can verify this by trying the monitor on another system
or trying a different monitor on this system. Contact your service representative or authorized
dealer for assistance.
Characters are distorted or incorrect
Check the following:
Are the brightness and contrast controls properly adjusted on the video monitor? See the
manufacturer's documentation.
Are the video monitor signal and power cables properly installed?
Is the correct monitor/video board installed for your operating system?
If the problem persists, the video monitor may be faulty or it may be the incorrect type. Contact
your service representative or authorised dealer for assistance.
System cooling fans do not rotate properly
If the system cooling fans are not operating properly, system components could be damaged.
Check the following:
Is AC power available at the wall outlet?
Are the system power cords properly connected to the system and the wall outlet?
Did you press the power on/off push-button switch?
Is the power-on light lit?
Have any of the fan motors stopped (use the server management subsystem to check the fan
status)?
Are the fan power connectors properly connected to the baseboard?
Is the cable from the front panel board connected to the baseboard?
Are the power supply cables properly connected to the baseboard?
Are there any shorted wires caused by pinched cables or power connector plugs forced into
power connector sockets the wrong way?
If the switches and connections are correct and AC power is available at the wall outlet, contact
your service representative or authorised dealer for assistance.
