The Redundancy Memory Xchange (RMX) module operates as a dedicated link between
CPUs in an RX3i Hot Standby CPU (IC695CRU320) Redundancy system. The RMX modules
provide a path for transferring data between the two redundancy CPUs in the redundant
system. A complete communications path consists of one RMX in the primary unit, one RMX
in the secondary unit, and two high-speed fiber optic cables connecting them to each other.
One or two redundancy links are supported per high availability CPU.
