24 10/100/1000 + Two 10 GbE + Two HiGig+ Stackable

The BCM56514 is the fifth generation of the highly-integrated and cost effective StrataSwitch and StrataXGS product line. The BCM56514 is a single-chip solution with 24-GbE ports and four 10-GbE/HiGig+ uplink ports.
The BCM56514 incorporates 24-GbE ports that can operate at 10/100/1000 Mbps. The uplink ports can operate in two modes: 10-GbE switching mode and HiGig+ uplink mode. The integrated 10-GbE switching ports are CX-4 compliant XAUI™ interfaces. The HiGig+ uplink interface is used to connect to other StrataXGS devices in a larger stacking system or to the BCM56700/BCM5675 switch fabric via a backplane in a multi-slot redundant chassis system.
