Recommended physical topology
The recommended minimum design for a scalable fabric is two chassis with Fabric A populated with redundant IOMs. Ideally, the
two chassis are located in separate racks on separate power circuits to provide the highest redundancy.
Additional chassis only have FEMs and the appear as the image below.

You can also use Fabric B to create a second scalable fabric:
NOTE:
The OME-Modular firmware version 1.20.10 supports additional but complex topologies and also Quad Port Ethernet
adapters. For more information, see the PowerEdge MX Network Architecture Guide available at https://
