The Supermicro SBM-GEM-001 Gigabit Ethernet switch module includes ten external 1-Gb/s uplink (RJ45) ports and fourteen internal 1-Gb/s downlink ports for connection to the SuperBlade's LAN interfaces.

This layer 2 Ethernet switching module also has two internal Ethernet paths to the CMM(s) to allow configuration, management, and control of the switch and its ports through a browser-based management interface. Offering such advanced features as link aggregation (static), VLAN support, and Jumbo Frame support, the switch provides a connection between the Ethernet controller integrated on the main board and external Ethernet systems.
