This section describes the configuration of the Dell MX9116n FSEs (Fabric Switching Engines) switches. Each PowerEdge MX7000 has one MX9116n and one MX7116n in the A fabric. The MX9116n in chassis 1 should be placed in the A1 slot and the MX9116n in chassis 2 should be placed in the A2 slot. This distributes the fabric's switching engines across both chassis. In the event of a loss of one of the MX9116n, only one half of the fabric is impacted. The two MX7116n expanders are installed in the remaining A fabric slots. The IP address of each switch module is assigned using the chassis management interface (MSM).
