Installing the Switch
The Switch in a Redundant Topology
The redundant topology increases the availability of a single switch by
protecting against single points of failure with the use of redundant switches
and power supplies (RPS).
All hardware and paths are redundant. If any hardware failure occurs, I/O
communication can still be completed through another path.
