Installation Guide

3. Install filters in the replacement fan-only module.

Install an air filter in the replacement FOM. Insert the air filter into the

narrow slot between the faceplate of the FOM and the fan. Position the air

filter with the plastic frame towards the fan, the quadrafoam towards the

faceplate, and the flextab to the top. The air filter should fit snugly.

4. Install the replacement fan-only module.

Caution Keep the FOM in straight alignment and insert it slowly. Forcing a

misaligned FOM is likely to damage both the chassis and FOM.

Slowly and carefully slide the replacement FOM into the cage, making sure

that the air filter and the flextab are clear of any contact points.

Firmly press the FOM until the faceplate engages, or nearly engages, the

chassis.

5. Secure the fan-only module.

Tighten the two captive screws on the faceplate of the FOM.
