A.6 Dell EMC Networking MX7116n Fabric Expander Module
The Dell EMC Networking MX7116n Fabric Expander Module (FEM) acts as an Ethernet repeater, taking
signals from attached compute sleds and repeating them to the associated lanes on the external QSFP28-DD
ports. The MX7116n FEM provides eight internal 25GbE connections to the chassis and two external
QSFP28-DD interfaces.
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 following MX7116n FEM components are labeled in Figure 100:
1. Express service tag
2. Supported optic LED
3. Power and indicator LEDs
4. Module insertion/removal latch
5. Two 200GbE QSFP28-DD fabric expander ports
NOTE: In this document, two MX7116n FEMs are used–one in each MX7000 chassis.
A.7 Dell EMC Networking MX5108n Ethernet switch
The Dell EMC Networking MX5108n Ethernet switch is targeted at smaller PowerEdge MX7000 deployments
using 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 25GbE layer 2 and layer 3 forwarding
capacity to all connected servers with no oversubscription.
In addition to eight internal 25GbE ports, the MX5108n provides the following external interfaces:
• One 40GbE QSFP+ port
• Two 100GbE QSFP28 ports
• Four 10GbE BASE-T ports
The ports can be used to provide a combination of network uplink, VLTi, or FCoE (FSB) connectivity. The
MX5108n does not support NPG or direct attach FC capabilities.
