Catalyst Wiring Closet Deployment Scenarios

Every network is unique, just like the organizations they serve. These diagrams illustrate four common deployments in wiring closets, utilizing Cisco Catalyst 2950, 3550, 4500, and 6500 switches. Depending on the size of the business, these could be linked into the core network layer. These are merely options, of course—the Cisco Catalyst family supports a far more diverse range of needs than those depicted here.
