System Cooling Fans Do Not Rotate
If the system cooling fans are not operating properly, system components could be
damaged.
Note:
In addition to the cooling fans that are an integral part of
each power supply, the server chassis has hot swap cooling fans.
There are no serviceable components inside the power supply. If the
power supply is opened, the manufacturer's warranty is voided.
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 front panel?
!
Are there any shorted/open wires caused by pinched cables or power connector plugs
forced incorrectly into sockets?
If the switches and connections are correct and AC power is available at the wall outlet,
contact your service representative or authorized dealer for assistance.
Diskette Drive Activity LED Does Not Light
Check the following:
!
Are the diskette drive 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 SSU 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.” To run the SSU, see Chapter 3
“Using the System Setup Utility (SSU)”.
If the problem persists, there may be a problem with the diskette drive, system I/O
carrier, or drive signal cable. Contact your service representative for assistance.
