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 which 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.
