H3C 0231A76H: 48-port 10/100/1000BASE-T Gigabit Ethernet switching module for the Switch 7700 chassis, sold under the 3Com badge via the H3C joint venture.
The H3C 0231A76H is a 48-port Gigabit Ethernet switching module for the Switch 7700 series modular chassis switch. It provides 48 x 10/100/1000BASE-T RJ-45 ports on a single blade for high-density copper aggregation within the 7700 chassis.
Like other Switch 7700 modules, the 0231A76H supports on-board local Layer 2 switching, keeping traffic local to the module where possible to reduce backplane and switch fabric loading and improve latency for time-sensitive traffic such as voice and video. It installs into one of the six I/O module slots on a Switch 7700 chassis.
The Switch 7700 platform was engineered by H3C, the joint venture between Huawei and 3Com, and sold under the 3Com badge; the 0231A order-code format on this module is H3C’s own numbering, so the listing carries the H3C name with the 3Com association noted.
