iChain
4.2.1
Introduction
iChain is a revolutionary network redundancy technology which enhances network redundancy for
any backbone network, providing ease-of-use and maximum fault-recovery times, flexibility,
compatibility, and cost-effectiveness. The self-healing Ethernet technology designed for distributed
and complex industrial networks enables the network to recover in less than 30 milliseconds (in full-
duplex Gigabit operation) or 10 milliseconds (in full-duplex Fast Ethernet operation) for up to 250
switches if at any time a segment of the chain fails.
iChain allows multiple redundant rings of different redundancy protocols to interoperate together as
a large robust network topology. I t can create multiple redundant networks beyond the limitations
of current redundant ring technologies.

Configurations
iChain is very easy to configure and manage. Only one edge port of the edge switch needs to be
defined. Other switches beside them just need to have iChain enabled.
