Installing the Switch Chassis
• 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 a front-mount bracket so that four of its screw holes are aligned to the screw holes on the side of the chassis.
Note You can align any four of the holes in the front rack-mount bracket to four of the six screw 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).
1 Front rack-mount bracket aligned to the port end of
the chassis
2 Four M4 screws used to attach the bracket to the
chassis
3 Rear rack-mount guide aligned to the module end of
the chassis
4 Two M4 screws used to attach the bracket to the
chassis
c) Secure the front-mount bracket to the chassis using four M4 screws and tighten each screw to 12 in-lb (1.36 N·m)
of torque.
d) Repeat Step 1 for the other front rack-mount bracket on the other side of the switch and be sure to position that bracket
the same distance from the front of the switch.
Step 2 Install the two rear rack-mount brackets on the chassis as follows:
5 Front rack-mount bracket aligned to the module end
of the chassis
6 Four M4 screws used to attach the bracket to the
chassis
7 Two M4 screws used to attach the bracket to the
chassis
8 Rear rack-mount guide aligned to the port end of the
chassis
