Cisco Catalyst 2955S-12 Managed Ethernet Switch with Single Mode Uplinks

The Cisco Catalyst 2955S-12 switch provides wire-speed Fast Ethernet and Gigabit Ethernet connectivity for deployment in harsh environments. The Cisco Catalyst 2955S-12 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 2955S-12 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. The Cisco IOS Software functionality for traditional data, video and voice services, with enhanced intelligent services features for additional security, advanced QoS and high availability. Intelligent services are critical in supporting the reliability and 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 and security filtering, helping to ensure the high uptime, low latency, deterministic performance and data integrity critical for industrial automation control networks.
