 Series Switches

Cisco Catalyst

®

 2955 Series switches are

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.

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, and

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

CiscoWorks.

This product line offers 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.
