Cisco WS-X4582E Line Card For Catalyst 4500 Series

Cisco WS-X4582E is a Catalyst 4500 Series line card that provides 12 Gigabit Ethernet interfaces with SFP cages, purpose-built for Cisco Catalyst 4500 E-Series switches. The card is designed to slot into Catalyst 4500E chassis to expand port capacity and support flexible fiber connectivity through SFP transceivers, enabling uplink and server connections in campus or data-center networks. As part of the 4500E family, the WS-X4582E supports fiber-based options via its SFP cages, offering modular scalability for deployments that require additional 1-Gigabit connectivity without replacing existing equipment. Typical use cases include edge access aggregation, server connectivity, and uplink diversification within a single chassis-based switch deployment.
