Cisco Catalyst 2955 switches can be conﬁgured either as “command” or “member” switches in a Cisco switch

cluster. Cisco CMS also allows users to designate a switch as a standby or redundant command, which takes the

commander duties if the primary command switch fails. Other key features include the ability to conﬁgure multiple

ports and switches simultaneously, to perform software updates across the entire cluster at once, and to clone

conﬁgurations to other clustered switches for rapid network deployments. Bandwidth graphs and link reports

provide useful diagnostic information, and the topology map gives network administrators a quick view of the

network status.

In addition to Cisco CMS, Cisco Catalyst 2955 Series switches provide extensive management tools using SNMP

platforms such as CiscoWorks for Switched Internetworks.

Cisco Catalyst 2955 Series switches deliver a comprehensive set of management tools to provide the required

visibility and control in the network. Managed with CiscoWorks, Cisco Catalyst switches can be conﬁgured and

managed to deliver end-to-end device, VLAN, trafﬁc, and policy management. Coupled with CiscoWorks, Cisco

Resource Manager Essentials, a Web-based management tool, offers automated inventory collection, software

deployment, easy tracking ofnetwork changes,views intodevice availability, and quick isolation of error conditions.

Enhanced Hardware Features

The Cisco Catalyst 2955 Switchhas been designed fordeployment in harshenvironments. Through the useof special

thermal design techniques and industrial-rated components, the Cisco Catalyst 2955 is rated to operate at extreme

temperatures (–40 to 60 C; –40 to 140 F). Robust mechanical speciﬁcations allow for its deployment as a mobile

platform and under extreme vibration and shock environments (50G trapezoidal shock pulse). The compact form

factor, DIN rail mounting, and dual cabling orientations facilitate its deployment into industrial enclosures, trafﬁc

control cabinets, and transportation vehicles. Two normally open relays can be associated with the different port

alarms, power alarms, and high temperature conditions to send an output signal to other external mechanisms

(visible or audible alarms, for example), HMIs, or PLCs for a controlled shutdown. Dual power inputs provide for

optional redundant power supplies, guaranteeing an even higher level of resiliency and reliability.
