System Cooling Fans Do Not Rotate

Note: The system has a cooling fan module (containing either two or three fans) behind the hard disk drives. In addition, there are two fans one directly in front of and one directly behind the system board, including a place reserved for an optional fan directly under the rear fan, and another cooling fan that is an integral part of each power supply. There are no serviceable components inside the power supply. If the power supply is opened, the manufacturer's warranty is voided.

Check the following:

nIs AC power available at the wall outlet?

nAre the system power cords properly connected to the power supplies and the AC wall outlets?

nAre the power connectors for the cooling fan module and fans connected to the system board?

nIs the front panel power on indicator lit?

If the switches and connections are correct and the power outlet is functioning, the power supply has probably failed. Contact your service representative for assistance.

Diskette Drive Activity LED Does Not Light

Check the following:

nAre the diskette drive's power and signal cables properly installed?

nIs the diskette drive properly configured?

nIs 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 Setup or the SSU to make sure that Onboard Floppy is set to Enabled. Conversely, to use an optional fixed/diskette controller, make sure that Onboard Floppy is set to Disabled. For information about running Setup or the SSU, refer to the “Configuring Your System” chapter.

If the problem persists, there may be a problem with the diskette drive, system board, or drive signal cable. Contact your service representative for assistance.
