Redundant Ports

Some modules have redundant ports. See the ERX Module Guide for specifications. Cabling both ports provides a redundant path to the module.

CAUTION: For port redundancy to operate correctly on a GE I/O module that supports SFPs, both the primary and redundant ports on an E-series GE I/O module must use the same type of SFP.
