Installing the Chassis
• The rack is installed and secured to its location.
Step 1 Install two rack-mount brackets to the rack 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 front-mount
brackets so that the switch ports will be in the cold aisle.
• If the switch has port-side exhaust modules (fan modules with blue coloring), position the front-mount brackets
so that the switch fan and power supply modules will be in the cold aisle.
b) Position a front-mount bracket so that it aligns to the desired position in the rack and secure the bracket with 12-24
screws or 10-32 screws, depending on the rack thread type (see the following figure). Tighten 12-24 screws to 30
in-lb (3.39 N·m) of torque and tighten 10-32 screws to 20 in-lb (2.26 N·m) of torque..
c) Repeat Step 1 for the other front rack-mount bracket on the other side of the rack and be sure to position that bracket
horizontally to the same level as first bracket.
