HSR
HSR applies the PRP principle of parallel operation to a single ring, treating the two
directions as two virtual LANs. For each frame sent, a node, DAN, sends two frames, one
over each port. Both frames circulate in opposite directions over the ring and each node
forwards the frames it receives, from one port to the other. When the originating node
receives a frame sent to itself, it discards that to avoid loops; therefore, no ring protocol is
needed. Individually attached nodes, SANs, such as laptops and printers, must be attached
through a "redundancy box" that acts as a ring element. For example, a 615 or 620 series
protection relay with HSR support can be used as a redundancy box.

LAN A of one device should connect to LAN B in the next device in the
ring. Do not connect LAN A to LAN A or LAN B to LAN B.
