Fast Ethernet Desktop Switches


The Cisco Catalyst


2950 Series of fixed

configuration, wire-speed Fast Ethernet desktop

switches delivers premium performance and

functionality for local-area networks (LANs). These

standalone, 10/100 autosensing switches provide

enhanced quality of service (QoS) and multicast

management features—managed with the

easy-to-use, Web-based Cisco Cluster Management

Suite (CMS) and integrated Cisco IOS



The Catalyst 2950 Gigabit-over-copper version with

10/100/1000BaseT uplinks offers medium-sized

businesses and enterprise branch offices with an ideal

solution to migrate from Fast Ethernet to a

higher-performance Gigabit Ethernet backbone using

existing Category 5 copper cabling.

The Catalyst 2950 Series consists of the Catalyst

2950T-24, 2950-24, 2950-12, and 2950C-24 switches.

The Catalyst 2950-24 Switch provides 24 10/100

ports; the 2950-12 has 12 10/100 ports; the 2950T-24

has 24 10/100 ports with 2 fixed 10/100/1000BaseT

uplink ports; and the 2950C-24 has 24 10/100 ports

with 2 fixed 100BaseFX uplink ports. Each switch has

a one rack-unit (RU) form factor, making them very

flexible to deploy, either on a desktop or mounted in a

wiring closet (Figure 1).
