1.8 Replacing the External Redundant
System Fan
An external redundant fan is pre-installed at the factory. This allows the system to
operate properly if the internal housing fan fails.
To replace the external redundant fan:
1. Open the front panel and remove the left panel of the housing. See section 1.4
for more information on opening the housing panels.
2. Use a screwdriver to push open the plastic peg located below the internal
system fan module.
3. Insert the redundant fan into the fan cage and attach the fan cage to the system
housing with four screws as shown below.
4. Insert the fan cable into the peg hole and attach the cable to the system board.
Please refer to Chapter 2 (System Board) for the location of the fan connector.
