Cisco WS-X4013+10GE enterprise networking (router/Catalyst switch/UCS families) Switch / Carrier Ethernet Line Card

The Cisco WS-X4013+10GE is a Supervisor Engine II-Plus-10GE for the Catalyst 4500 chassis, combining switch supervisor functions with two 10-Gigabit Ethernet uplink ports (X2) and four 1-Gigabit Ethernet ports (SFP) on a single module. It manages the switch fabric, routing and control-plane functions for a Catalyst 4500-series chassis while also providing high-bandwidth uplinks suited to data centre and campus distribution roles where 10GE aggregation is needed above the access layer. Catalyst 4500 chassis of this generation remain in service in many established enterprise networks, and a supervisor module is one of the most critical spares to hold given a chassis cannot operate without one. Tech-Star (UK-based, shipped worldwide) supplies Cisco supervisor modules. Confirm exact Catalyst 4500 chassis compatibility (redundant-supervisor slot support, IOS version) before ordering.
