Cisco WS-X6416-GBIC enterprise networking (router/Catalyst switch/UCS families) Switch / Carrier Ethernet Line Card

The Cisco WS-X6416-GBIC is a Catalyst 6000-series 16-port Gigabit Ethernet line card using GBIC transceivers, in the classic (non fabric-enabled) configuration that switches through the chassis’s shared backplane bus rather than a dedicated crossbar fabric. It was one of Cisco’s earlier high-density Gigabit line cards for the Catalyst 6000 platform, predating the fabric-enabled 6516-GBIC card that later offered a dedicated fabric connection for higher aggregate throughput.

GBIC-based ports let the operator fit whichever transceiver type and reach each port needs, copper, multimode or single-mode fibre, rather than being locked to one media type per card. Catalyst 6000 chassis fitted with classic-bus supervisors and line cards of this generation remain in service on some established networks that have not upgraded to fabric-enabled hardware. Tech-Star (UK-based, shipped worldwide) can confirm compatibility with your specific chassis and supervisor on request.
