Install the WF-500-B Appliance in a 4-Post Rack

1. Attach the inner-rails to each side of the appliance by aligning the square holes on each rail with the rail hooks on the appliance and then sliding the rails toward the front of the appliance to engage the hooks. Secure the back part of each rail to the appliance using one M4 screw for each rail.
   The inner-rails also use a pressure-lock clip (one on each rail) that locks the rails to the appliance. Remove the M4 screw and pull the metal tab on the clip to remove the rail from the appliance.

2. Install one outer rack-mount rail to each side of the equipment rack. Push the two rail hooks (on the front and back of each rail) in to the square rack holes and push down to engage the hooks. The release buttons located above each rail hook will depress as you push the rail hooks in to the square holes. Secure the back of each rail to the rack using two M5 screws (with washers) for each rail. The following image shows the right side of the rack if you are facing the front of the rack.

3. Install the appliance in to the equipment rack by sliding the inner-rails in to the outer rack-mount rails until the appliance stops (about halfway in to the rack). Push the inner-rail release clips on each side of the two rails to release the appliance and then continue to slide the appliance in to the rack until the front of the appliance is flush with the front of the rack. The inner-rail release clips are shown in step 1.

4. Secure the front of the appliance to the rack by turning the front thumb screws on each rail clockwise until tight.
