Redundant Ports

The Next Step

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.
