Dell EMC Networking MX9116n Fabric Switching
Engine
The Dell EMC Networking MX9116n Fabric Switching Engine (FSE) is a scalable, high-performance, low latency 25 GbE switch purpose-
built for the PowerEdge MX platform. The MX9116n FSE provides enhanced capabilities and cost-effectiveness for enterprise, mid-
market, Tier 2 cloud, and Network Functions Virtualization (NFV) service providers with demanding compute and storage traffic
environments.
In addition to 16 internal 25 GbE ports, the MX9116n FSE provides:
Two 100 GbE QSFP28 ports
Two 100 GbE QSFP28 unified ports
Twelve 2x100 GbE QSFP28-Double Density (DD) ports
The QSFP28 ports can be used for Ethernet uplink connectivity. For more information, see Management host section. The unified ports
can be used for Ethernet uplink connectivity and supporting eight 32 Gb Fibre Channel (FC) ports for SAN connectivity supporting both
NPIV Proxy Gateway (NPG) and direct attach FC capabilities.
The QSFP28-DD ports provide fabric expansion connections for up to nine more PowerEdge MX7000 chassis using the MX7116n Fabric
Expander Module. The QSFP28-DD ports also provide capacity for extra uplinks, VLTi links, and connections to rack servers at 10 GbE or
25 GbE using breakout cables. The PowerEdge MX7000 chassis supports up to four MX9116n FSEs in Fabric A or B, or both.

Dell EMC Networking MX7116n Fabric Expander
Module
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 PowerEdge MX7000 chassis supports up to four MX7116n FEMs in
Fabric A or Fabric B, or both.
