1. Align the tabs on the fan carrier assembly with the guide slots on the server and slide the
assembly into the server. See Figure 6-19.
2. Rotate the fan carrier assembly handle downward approximately 90 degrees until it closes
flush against the airflow guide.
3. Install the fans in to the fan carrier. See “Replacing a Server Fan ” (page 152).
4. Replace the top cover. See “Replacing the Top Cover” (page 144).
5. If rack mounted, slide the server completely into the rack. See “Inserting the Server into the
Rack” (page 143).
6. Reconnect the power cables and power on the server. See “Powering On and Powering Off
the Server” (page 78).
Removing and Replacing the I/O Fan Carrier Assembly
The server contains an I/O fan carrier assembly, located behind the SAS backplane, that houses
four of the 12 server fans in the Data Center server, or two of the six fans if you have an Office
Friendly Server.
WARNING! Ensure that the system is powered off and all power sources are disconnected
from the server prior to performing this procedure.
Voltages are present at various locations in the server whenever an ac power source is connected.
This voltage is present even when the main power switch is in the off position.
Failure to observe this warning can result in personal injury or damage to equipment.
CAUTION: Observe all ESD safety precautions before attempting this procedure. Failure to
follow ESD safety precautions can result in damage to the server.
Removing the I/O Fan Carrier Assembly
This procedure applies to both the Data Center server and Office Friendly server.
To remove the I/O fan carrier assembly, follow these steps:
1. Power off the server and disconnect the power cables. See “Powering On and Powering Off
the Server” (page 78).
2. If rack mounted, slide the server completely out from the rack. See “Extending the Server
from the Rack” (page 142).
3. Remove the top cover. See “Removing the Top Cover” (page 143).
4. Disconnect the I/O fan carrier assembly power cable (1). See Figure 6-22 for the Data Center
server, or Figure 6-23 (page 165) for the Office Friendly server.
5. Remove the fans from the I/O fan assembly. See “Removing a Server Fan” (page 150).
6. Loosen the four T-15 screws that hold the I/O fan assembly to the system board. See
Figure 6-22 (page 165) for the Data Center server, or Figure 6-23 for the Office Friendly server.
