CHAPTER OVERVIEW

Redundancy is transparent backup. It is required where a single point of failure cannot be tolerated, so is
required in critical applications such as substation automation. Redundancy acts as an insurance policy,
providing an alternative route if one route fails.
The Redundant Ethernet Board (REB) assures "bumpless" redundancy at the intelligent electronic device
(IED) level. "Bumpless" in this context means the transfer from one communication path to another without
noticeable consequences.
