The Cisco Catalyst 2955C-12 is a member of the Catalyst 2955 Series, and is an industrial-grade switching products that provide wire-speed Fast Ethernet and Gigabit Ethernet connectivity for deployment in harsh environments. The Cisco Catalyst 2955 Series operates in environments such as industrial networking solutions (industrial Ethernet deployments), intelligent transportation systems (ITS), and transportation network solutions. It integrates into military equipment, Supervisory Control and Data Acquisition (SCADA) systems, power generation systems, waste water treatment facilities, building automation systems, warehouses, and any other facilities or applications where the environmental conditions or suspended solid concentrations exceed the specifications of other commercial switching products. The Cisco Catalyst 2955 Series uses industrial-grade components, a compact form factor, convection cooling, and relay output signaling to extend intelligent services such as enhanced security, high availability, and advanced quality of service (QoS) to areas that cannot be served by traditional commercial-grade Ethernet switches.
