Great Switch!

The Cisco 4500 line makes a good core switching solution for smaller installations, and a good distribution solution for larger ones.

This machine provides redundant power capability and can be equipped with a wide range of interfaces, including 10/100/1000 copper, Fiber, and PoE (power over ethernet) solutions.

Since this machine lacks redundant supervisor capability, you should seriously consider the 4507R in mission-critical environments.
