Replacing the I/O Fan Carrier Assembly
This procedure applies to both the Data Center server and Office Friendly server.
To replace the I/O fan carrier assembly:
1. Align the pins on the system board with the holes in the I/O fan assembly, and put the assembly
straight down into the server.
2. Attach the assembly to the server chassis by tightening the four T-15 screws. See Figure 58
(page 162) or Figure 59 depending on your server type.
3. Install the fans into the I/O fan carrier assembly. See “Replacing a Server Fan ” (page 149).
4. Reconnect the I/O fan carrier assembly power cable. See Figure 58 (page 162) or Figure 59
(page 162).
5. Replace the top cover. See “Replacing the Top Cover” (page 142).
6. If rack mounted, slide the server completely into the rack. See “Inserting the Server into the
Rack” (page 141).
7. Reconnect the power cables and power on the server. See “Powering On and Powering Off
the Server” (page 77).
Removing and Replacing the I/O Backplane Assembly
The I/O backplane assembly consists of the I/O backplane and a sheet metal enclosure. The I/O
backplane contains three full-length public I/O slots.
Removing the I/O Backplane Assembly
Observe the following warning and cautions before removing the I/O backplane assembly.
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.
These voltages are 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.
CAUTION: Record the slot location of all PCI cards as they are removed. Depending on the
operating system, replacing PCI cards in a different location might require system reconfiguration
and might cause boot failure.
To remove the I/O backplane assembly:
1. Power off the server and disconnect the power cables. See “Powering On and Powering Off
the Server” (page 77).
2. If rack mounted, slide the server completely out from the rack. See “Extending the Server from
the Rack” (page 141).
3. Remove the top cover. See “Removing the Top Cover” (page 142).
4. Disconnect all internal and external cables attached to the I/O cards in the I/O backplane
assembly.
