1. Hirschmann‘s RS2-FX/FX Fast Ethernet Rail Switch
HiPER Ring – Network Redundancy
How does HIPER-Ring redundancy work?
...and how can you build a redundant and secure network
Hirschmann‘s RS2-FX/FX
Fast Ethernet Rail Switch
using Hirschmann‘s managed industrial Ethernet switches (RS2-XX/XX and MICE Series)?

3. Fiber optic or twisted pair backbone2
Hirschmann switches can interconnect the four areas via twisted pair or fiber optic cable.

4. Is this network resilient enough?3
If only one of the three backbone connections fail, communication will be lost to one or more areas.

5. Solution via HiPER-Ring!4
Creating a redundant ring prevents communication loss should one of the backbone links fail.

6. Enabling HiPER-Ring!
To create a HiPER-Ring, activate the Redundancy Manager on one of Hirschmann’s managed switches via integrated DIP switch. 5

7. HiPER-Ring Watchdog Packets
Watchdog packets pass through redundant link while normal Ethernet traffic cannot.
The Redundancy Manager sends out watchdog packets to test the integrity of the ring. 6

8. HiPER-Ring resiliency
All switches on the ring re-learn their connections and communication is re-established within a maximum of 300 milliseconds!
If the Redundancy Manager does not receive the watchdog packets, it immediately activates the redundant connection.

9. Restoring broken link
As before, the network switches over within a maximum of 300 milliseconds and continues to monitor network integrity.
When the broken connection is repaired, the Redundancy Manager sets the network into it’s normal operational mode.
