Installing the Switch Using the NXK-ACC-KIT-1RU Rack-Mount Kit
• The rack is installed and secured to its location.
Step 1 Install two front rack-mount brackets and the two rear rack-mount brackets to the switch as follows:
a) Determine which end of the chassis is to be located in the cold aisle as follows:
• If the switch has port-side intake modules (fan modules with burgundy coloring), position the switch so that its
ports will be in the cold aisle.
• If the switch has port-side exhaust modules (fan modules with blue coloring), position the switch so that its fan
and power supply modules will be in the cold aisle.
b) Position the front rack-mount bracket and the rear rack-mount bracket so that its screw holes are aligned to the screw
holes on the side of the chassis.
Note You can align the holes in the rack-mount bracket to the holes on the side of the chassis (see the two ways
to mount these brackets on a typical chassis, in following figure). The holes that you use depend on the
requirements of your rack and the amount of clearance required for interface cables (3 inches [7.6 mm]
minimum) and module handles (1 inch [2.5 mm] minimum).
c) Secure the front-mount bracket and the back-mount bracket to the chassis using four M4 screws and tighten each
screw to 12 in-lb (1.36 N·m) of torque.
