Cisco Catalyst 2955 Series switches are industrial-grade switching products that provide wire-speed Fast Ethernet & 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), & transportation network solutions. It integrates into military equipment, Supervisory Control & Data Acquisition (SCADA) systems, power generation systems, waste water treatment facilities, building automation systems, warehouses, & 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, & relay output signaling to extend intelligent services such as enhanced security, high availability, & advanced quality of service (Qo S) to areas that cannot be served by traditional commercial-grade Ethernet switches. Embedded in Cisco Catalyst 2955 Series switches is Cisco Cluster Management Suite (CMS) Software. This network management solution allows administrators to easily configure features, monitor performance, & troubleshoot multiple Cisco Catalyst switches using a standard Web browser. For larger deployments, Cisco Catalyst 2955 Series switches support Simple Network Management Protocol (SNMP)-based network management platforms such as Cisco Works. This product line offers Cisco IOS Software functionality for traditional data, video, & voice services, with enhanced intelligent services features for additional security, advanced Qo S, & high availability. Intelligent services are critical in supporting the reliability & determinism of proprietary Layer 2 solutions typical of industrial Ethernet deployments, while providing the advantages (standardization, open connectivity, bandwidth, integration, etc.) of an advanced Ethernet switching architecture. These intelligent services include Layers 2-4 traffic prioritization, rate limiting, & security filtering, helping to ensure the high uptime, low latency, deterministic performance, & data integrity critical for industrial automation control networks.
