Replacing a CPU Fan

CRU Replacement Procedures 5-41

Replacing a CPU Fan

Each CPU- I ⁄ O enclosure contains two CPU fans, regardless of the number of CPUs

installed.

Estimated time: Ten minutes.

Tools: ESD strap.

1. Remove the CPU-I/O enclosure.

2. With the enclosure on a stable, flat surface, remove the enclosure cover.

3. Disconnect the fan power connector from the main board by pulling straight up on

the connector (Figure 5-26). If necessary, push the IDE ribbon cable aside to

access the connector.

NOTE

Pull on the connector (not the wires) to disconnect the

power cable.

4. Carefully remove the fan power cable (number 2 in Figure 5-26) from the guides on

the CPU plenum.

5. Pull the fan straight up to remove it from the enclosure (Figure 5-27). Set the

defective fan aside for repacking. See “Repacking CRUs” on page 4-3.
