Troubleshooting
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 not, see “
If your system has LED lights for the fans, is one or more of these LEDs lit?
Are any other control 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 control panel board connected to the both the control panel board and to
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 onboard diskette controller, use the BIOS setup to make sure that “Onboard
Floppy” is set to “Enabled.” If you are using an add-in diskette controller, make sure that
“Onboard Floppy” is set to “Disabled.”
