Catalyst 4948E and Catalyst 4948E-F Switch Installation Guide

OL-21561-02

Product Overview

Revised: January 4, 2012

Both the Catalyst 4948E switch and the Catalyst 4948E-F switch are 1-RU, horizontal,

fixed-configuration chassis with 48 10/100/1000 downlink ports and 4 1-GB or 10-GB uplink ports. Both

switches have one removable fan tray and support redundant power supplies. The primary difference

between the two chassis is that the air flow in the Catalyst

4948E goes from the front of the chassis to

the rear of the chassis while the air flow in the Catalyst 4948E-F goes from the rear of the chassis to the

front of the chassis.

Figure 1-1 shows the front view of both chassis with the major features identified

and Figure 1-2 shows the rear view of both chassis with the major features identified.

Note The fan trays and the power supplies are not interchangeable between the Catalyst 4948E and the

Catalyst 4948E-F switch chassis.

Tip For additional information about the Cisco Catalyst 4948E and the Catalyst 4948E-F switches (including
