An additional external redundant fan can be installed behind the system housing. This allows the system to operate properly even
though the internal housing fan failed.
To install an external redundant fan:
1.
Open the front panel and remove the left panel of the housing. See section 1.4.1 for more information on opening the housing
panels.
2.
Use the 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.
