Installing a Fan-Only Module
Before you begin:
■ Read the safety information for the switch.
Safety information is available in the Rapier 48w Switch Installation and Safety
Guide bundled with every Rapier 48w switch. You can also download this
document from www.alliedtelesis.com/support/software.
■ Gather necessary tools and equipment.
You will need a flat screwdriver to adjust the captive screws on the FOM.
We recommend installing new air filters when you replace a FOM. Air
filters must be purchased separately from your authorised Allied Telesis
distributor or reseller.
■ Verify the package contents if you have not already done so.
See “Package Contents” on page 3. Contact your authorised distributor or
reseller if items are damaged or missing.
You do not need to power down the switch to change a FOM, but you should
replace FOMs one at a time.

1. Unpack the fan-only module.
Caution Follow correct anti-static procedures when installing a FOM.
Failure to do so could damage the FOM or the switch. If you are unsure
about correct procedures, contact your authorised distributor or reseller.
While observing Electrostatic Discharge (ESD) precautions, remove the
FOM from its packing material in an anti-static environment.
2. Remove the current fan-only module from the switch.
Using a flat screwdriver, loosen the captive screws on the faceplate of the
FOM, and slide the FOM out of its cage. The internal power connection is
quite solid so pull firmly on the captive screws.

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.
