Table 10 shows the port mapping for fabric A. The MX9116n FSE in slot A1 maps dual-port mezzanine cards
to odd-numbered ports. The MX7116n FEM, connected to the MX9116n FSE, maps to virtual ports with each
port representing a compute sled attached to the MX7116n FEM.

A.9 Scalable fabric architecture overview
A new concept with the PowerEdge MX platform is the scalable fabric architecture. A scalable fabric spans
multiple chassis and allows them to behave like a single chassis from a networking perspective.
A scalable fabric consists of two main components, a pair of MX9116n FSEs in the first two chassis, and
additional pairs of MX7116n FEMs in the remaining chassis. Each MX7116n FEM connects to the MX9116n
FSE corresponding to its fabric and slot. All IOMs participating in the fabric are configured in either Full Switch
or SmartFabric mode.
