Refer to the documentation that came with each device for more information on
connecting it to your system.
This section provides instructions for the following procedures:
• "Replacing the Fan Wall" on page 87
• "Replacing the Hard Disk Drive Fan" on page 89
• "Replacing the Rear Fan Assembly" on page 92
Caution: Never operate the unit without all of the cooling system components in place.
Operating the system without the proper cooling equipment may damage the internal
components.
The fan wall cools the interface board, the PCI boards, and the graphics module. Follow
these steps to replace the fan wall (see Figure 3-29).
Note: If you have not already done so, prepare your system for service. Refer to
"Preparing the System for Service" on page 44. In order to remove the fan wall, you must
remove the left side panel.
1. Disconnect the fan wall power cable from the interface board. Then remove the
screw that secures the fan wall to the chassis. If there is an XIO board support
bracket installed on the fan wall, remove the screw that secures the XIO board to the
support bracket.
2. Slide the fan wall straight out of the chassis. Place it in a secure location.
3. Slide the replacement fan wall into the enclosure. Then install the screw that secures
the fan wall to the chassis.
