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.

Note
The fan trays and the power supplies are not interchangeable between the Catalyst 4948E and the
Catalyst 4948E-F switch chassis.
