Cisco WS-C6503-E Catalyst 6500 Series Enhanced 3-slot chassis is a 4RU enclosure designed to host three expansion slots for Catalyst 6500 line cards and related modules. This chassis ships without a power supply or fan tray, meaning PS and cooling components must be added separately. As part of the Catalyst 6500 family, it provides a modular platform for scalable enterprise networking, enabling multiple line cards in a single chassis to support a range of interfaces and performance requirements.
