The Dell EMC Networking MX7116n Fabric Expander Module (FEM) acts as an Ethernet
repeater, taking signals from an attached compute sled and repeating them to the
associated lane on the external QSFP28-DD connector. The MX7116n FEM provides two
QSFP28-DD interfaces, each providing up to eight 25 GbE connections to the chassis.
There is no operating system or switching ASIC on the MX7116n FEM, so it never
requires an upgrade. There is also no management or user interface, making the
MX7116n FEM maintenance-free. The MX7000 chassis supports up to four MX7116n
FEMs in Fabric A and/or B. See Appendix A for more information.

Note:
The MX7116n FEM cannot act as a stand-alone switch and must be connected to the
MX9116n FSE to function.
The Dell EMC Networking MX5108n Ethernet switch is targeted at small PowerEdge
MX7000 deployments of one or two chassis. While not a scalable switch, it still provides
high-performance and low latency with a non-blocking switching architecture. The
MX5108n provides line-rate 25 Gbps Layer 2 and Layer 3 forwarding capacity to all
connected servers with no oversubscription.
Besides eight internal 25GbE ports, the MX5108n provides:
•
One 40GbE QSFP+ port
•
Two 100GbE QSFP28 ports
•
Four 10GbE RJ45 BASE-T ports
