Install the WF-500-B Appliance
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.
STEP 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
