Problem Solving 5-11
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 has cooling fans. There are no
serviceable components inside the power supply. If the power supply
is opened, the manufacturer's warranty is voided.
The CPU module has both a rear cooling fan and a front cooling fan. The front cooling
fan is mounted at an upward angle in order to cool the hard disk drives. The I/O module
only has a rear cooling fan.
Check the following:
!
Is AC power available at the wall outlet?
!
Are the system power cords properly connected to the power supplies and the AC
wall outlets?
!
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 cooling fans power connectors seated properly?
!
Is the front panel power on indicator lit?
If the switches and connections are correct and the power outlet is functioning properly,
contact your service representative for assistance.
Diskette Drive Activity LED 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.
Use BIOS Setup to make sure that the diskette drive controller is set to Enabled. For
information about running BIOS Setup, refer to the
Configuring Your System
chapter.
If the problem persists, there may be a problem with the diskette drive, device
backplane boards, or drive signal cable. Contact your service representative for
assistance.
