The BCM56501 is the fifth generation of the highly-integrated and cost effective StrataSwitch and StrataXGS product line. The BCM56501 is a single-chip solution with four 10-GbE/HiGig+ uplink ports.

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 BCM5675/BCM5676 Switch Fabric via a backplane in a multi-slot redundant chassis system.
