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.
2. Remove the two side plates on the front (port) side of the chassis.
3. Attach the larger side plates from the recessed mount kit using 24 screws (12 per side).

4. Prepare the device for mounting by attaching the lift to the device chassis.
5. Using the lift, raise the device to the correct level.
6. If applicable, lock the wheels of the lift.
7. Ensure that the device is oriented so that the front (port side) has access to intake air.
