The Dell PowerEdge MX8116n FEM acts as an Ethernet repeater, taking signals from an attached compute sled and repeating them to the associated lane on the external QSFP56-DD connector. The MX8116n FEM also includes two QSFP56-DD interfaces, with each interface providing up to four 100 Gbps connections to the chassis and eight internal 100 GbE server facing ports.
The MX7000 chassis supports up to four MX8116n FEMs in Fabric A and Fabric B.
