Cisco Catalyst Modular Switches
The Cisco Catalyst 6500 and Catalyst 4500 Series modular switches
provide customers with an intelligent platform for deploying numerous,
concurrent intelligent services without degrading the overall
performance of the switch. With a broad selection of line cards and
power supplies, and their highly versatile architecture, modular switches
deliver the highest levels of port density and flexibility, including Power
over Ethernet (PoE) and Enhanced Power over Ethernet (ePoE) scalability
to deploy new converged applications and extend investment protection
well into the future. The modular architecture also provides scalable
performance via a selection of supervisors that can be upgraded to
enhance the performance and service features of the entire switch
as needed.
To minimize costly user downtime, modular switches are optimized
for high availability. Critical redundant hardware and software features
deliver the highest resiliency for all places in the network. Another key
advantage is the ease of use of modular switches. Modular switches
have a single IOS image to manage, no matter how many line cards
are inserted. This allows for simpler IOS configurations, updating, and
management leading to a reduction in overall cost of ongoing operations.
