manufacturer’s documentation.
‰ Are the video monitor’s signal and power cables properly installed?
‰ Does this video monitor work correctly if plugged into a different system?
System Cooling Fans Do Not Rotate Properly
If the system cooling fans are not operating properly, it is an indication of possible system
component failure.
Check the following:
‰ Is the power-on light lit?
‰ If your system has LED lights for the fans, is one or more of these LEDs lit?
‰ Are any other front panel LEDs lit?
‰ Have any of the fan motors stopped? Use the server management subsystem to check the fan
status.
‰ Have your fans speeded up in response to an overheating situation?
‰ Have your fans speeded up in response to a fan that has failed?
‰ Are the fan power connectors properly connected to the server board?
‰ Is the cable from the front panel board connected to both the front panel board and the server
board?
‰ Are the power supply cables properly connected to the server board?
‰ Are there any shorted wires caused by pinched-cables or have power connector plugs been
forced into power connector sockets the wrong way?
Diskette Drive Activity Light Does Not Light
Check the following:
‰ Are the diskette drive’s power and signal cables properly installed?
‰ Are all relevant switches and jumpers on the diskette drive set correctly?
‰ Is the diskette drive properly configured?
‰ Is the diskette drive activity light always on? If so, the signal cable may be plugged in
incorrectly.
If you are using the on-board diskette controller, use BIOS Setup to make sure that “On-board
Floppy” is set to “Enabled.” If you are using an add-in diskette controller, make sure that “On-
board Floppy” is set to “Disabled.”
