Recessed mount
The procedure to install a recessed mount device in a four-post rack is the same as installing the device with a
ush mount, with the
addition of removing the side plates on the front of the device chassis, and installing the side plates from the recessed mount kit.
1. Install the two rails from the rack-mount kit for the four-post rack, with the rails perpendicular to the aisle. 16 fasteners are
required, 4 for each post.
• If the four-post rack has round, threaded screw holes, use 16 screws from the rack-mount kit, with no additional hardware,
to attach the kit to the posts.
• If the four-post rack has rectangular, unthreaded holes, use 16 screws, 16 nuts, and 16 alignment washers from the rack-
mount kit to attach the kit to the posts.
