This section describes how to use the rack mount kit to install the switch into a cabinet or rack that meets the
requirements described in the

Installing the Switch in a 4-Post Rack

To install the switch, you must attach the front and rear mounting guides to the switch, install the slider rails
on the rear of the rack, slide the switch into the slider rails, and secure the switch to the front of the rack.
Typically, the front of the rack is the side that is easiest to access for maintenance.
Before you begin
• Inspect the switch shipment to ensure that you have everything you ordered.
• Make sure that the switch rack-mount kit includes the following parts:
• The rack is installed and secured to its location.

1. Determine which end of the chassis is to be located in the cold aisle as follows:
a. If the switch has port-side intake modules (fan modules and power supply units with red coloring),
position the switch so that its ports are in the cold aisle.
b. If the switch has port-side exhaust modules (fan modules and power supply units with blue
coloring), position the switch so that its fan modules and power supply units are in the cold aisle.
2. Determine which way the chassis should slide in and out of the rack—port-side entry first or rear-side
entry first. You might consider whether the front or back of the rack provides better clearance for
maneuvering the chassis in and out during installation and servicing. The end that needs to enter the
rack first requires the guides and the other end the brackets.
