Replacing the Fan behind the SCSI Backplane
1.
Remove the top front chassis cover.
2.
Remove the two high-speed cooling fans behind the SCSI disk drive housing
first so that there is enough room for your hand to reach the fan behind the SCSI
backplane. (See Figure 3.7).
3.
Lift the tab on top of the fan unit so that the fan detaches from the fan enclosure.
Figure 3.9 is another view that shows fan removal. Using this way, you need to
remove the whole SCSI disk drive housing first. But it's not necessary to take
out the SCSI housing to replace the fan.
4.
Unplug the fan wire on the alarm board.
5.
Put a new fan into the fan enclosure carefully until it is locked in by the tab. Be
sure to install it securely in the enclosure.
6.
Plug the fan wire into the fan connector on the SCSI backplane.
7.
Replace the two high-speed cooling fans and fasten them.
8.
Replace the top front chassis cover.
