Middle Mount - Extreme Networks ExtremeRouting SLX 9850-4 Hardware Installation Manual

Middle mount

The procedure to install a mid mount device in a two-post rack is the same as installing the device with a flush 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 saddles from the rack-mount kit for the two-post rack using 12 screws (6 for each saddle).
• If the two-post rack has round, threaded screw holes, use 12 screws from the rack-mount kit, with no additional hardware,
to attach the saddles to the posts.
• If the two-post rack has rectangular, unthreaded holes, use 12 screws, 12 nuts, and 12 alignment washers from the rack-
mount kit to attach the saddles 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 mid mount kit using 16 screws (8 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.
8. Raise the device slightly above the level of the two saddles, and bring the chassis forward until the front plates touch the front of
the rack, then lower the device until it rests on the saddles.
