Cisco Catalyst 2950 Series Intelligent Ethernet Switches
Cisco Catalyst 2950 Series Intelligent Ethernet Switches
The Catalyst 2950 Series with Intelligent Ethernet Switches are
fixed-configuration, standalone and stackable models that provide
wire-speed Fast Ethernet and Gigabit Ethernet connectivity for small,
mid-sized, service provider and industrial networks. When a Catalyst 2950 Switch is
combined with a Catalyst 3550 Series Switch, the solution is capable of enabling IP routing
from the edge to the core of the network. These Intelligent Ethernet Switches come with
Enhanced Image (EI) software configuration only.
In addition to the range of Intelligent Ethernet switches, the Catalyst 2950 Series also
includes switches with Standard Image (SI) software configuration only and are standalone,
fixed-configuration, managed 10/100 switches with Gigabit uplinks (2950SX-48,
2950T-48, and 2950SX-24 only) providing user connectivity for small to mid-sized
networks. These wire-speed desktop switches come with Standard Image (SI) software
features and offer Cisco IOS functionality for basic data, video and voice services at the
edge of the network.
The Catalyst 2950 Series also includes the Cisco Catalyst 2955T-12, 2955C-12, and
2955S-12. The Cisco Catalyst 2955 are industrial-grade switches providing Fast Ethernet
and Gigabit Ethernet connectivity for deployment in harsh environments. It offers a range
of copper and fiber uplink options and operates in environments such as industrial
networking solutions (industrial Ethernet deployments), intelligent transportation systems
(ITSs), and transportation network solutions. It is also suitable for many military and utility
market applications where the environmental conditions or suspended solid concentrations
exceed the specifications of other commercial switching products.
