Cisco WS-X4515 enterprise networking (router/Catalyst switch/UCS families) Switch / Carrier Ethernet Line Card

The Cisco WS-X4515 is a Catalyst 4000/4500-series Supervisor Engine IV, fitted with two built-in Gigabit Ethernet uplink ports and an RJ-45 console port. It is the central switching and management module for the Catalyst 4000/4500 chassis family, providing Layer 2/3 switching capability along with the two onboard Gigabit uplinks needed to connect the chassis into the network core without consuming a line-card slot.

Supervisor Engine IV sat in the middle of Cisco’s Catalyst 4000/4500 supervisor line-up, offering more forwarding performance than the earlier Supervisor II/III generation while predating the later Supervisor Engine V/6/6-E modules. Chassis fitted with a Supervisor IV remain in service on established campus networks that have not migrated to newer supervisor hardware. Tech-Star (UK-based, shipped worldwide) can confirm compatibility with your specific chassis before ordering.
