Installing the Switch Chassis
• The rack is installed and secured to its location
Step 1 Install two front-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.
If the power supply modules have white coloring, look at the fan modules to determine the airflow direction
Note
for the switch.
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.
You can align any four of the holes in the front rack-mount bracket to four of the six screw holes on the side
Note
of the chassis (see the two ways to mount these brackets 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).
