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