Step 1
Install two rack-mount brackets to the router as follows:
a) Position the router so that its ports will be in the cold aisle.
b) With the bracket ears aligned to the front of the chassis, position a rack-mount bracket on the side of the chassis so
that the seven holes are aligned to seven of the screw holes on the side of the chassis.
c) Use seven M4 screws with 12 in-lbs (1.4 N-m) to attach the bracket to the chassis
d) Repeat Steps 1b and 1c with the other rack-mount bracket on the other side of the router.

Step 2
Install the router onto the 2-post rack as follows:
a) With two people, lift the router into position between the two rack posts.
b) Move the router until the rack-mount brackets come in contact with two rack posts.
c) Hold the chassis level while the second person inserts six screws (12-24 or 10-32, depending on the rack type) in
each of the two rack-mount brackets (using a total of twelve screws) and into the cage nuts or threaded holes in the
vertical rack-mounting rails.
d) Tighten the 10-32 screws to 20 in-lb (2.26 N.m) or tighten the 12-24 screws to 30 in-lb (3.39 N.m).
