Installing the Switch Using the NXK-ACC-KIT-1RU Rack-Mount Kit
b) Align the two rear rack-mount guides on either side of the switch with the slider rails installed in the rack. Slide the
rack-mount guides onto the slider rails, and then gently slide the switch all the way into the rack until the front
rack-mount brackets come in contact with two rack or cabinet posts.
c) Holding the chassis level, insert screws (12-24 or 10-32, depending on the rack type) in each of the two front rack-mount
brackets (using a total of six screws) and into the cage nuts or threaded holes in the vertical rack-mounting rails (see
the following figure).
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).
Step 5 If you attached a grounding wire to the chassis grounding pad, connect the other end of the wire to the facility ground.
