Dell EMC PowerEdge MX7000 Enclosure Installation and Service Manual

There are several connections on the Main Distribution Board to enable communication between the IOMs. Between each pair of IOMs (C1 and C2), there is a link for intermodule communication. This link is referred as Fabric-V in the schematics. This link supports a x1 connection with each lane operating up to 10 Gbps per direction. In addition to the Fabric-V, there are handshake signals between the two modules to facilitate redundancy/failover or other module to module communication. The usage of these interconnects depends on the IOM design and its particular requirements.
