Installing the Catalyst 4948E-F Switch Chassis with the Optional Panduit Air
Duct Kit
If you are installing the Catalyst 4948E-F switch chassis in a data center that is configured as hot isle
and cold isle, you might need to install the Panduit Air Duct kit, Model CDE2. The kit extends the air
intake from the rear of the chassis to the front of the equipment rack allowing the system to draw in cool
air from the cool isle. To install the air duct assembly, refer to the installation note that ships with the kit.
