Fiber optic or twisted pair backbone 2 Hirschmann switches can interconnect the four areas via twisted pair or fiber optic cable. Click to continue

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

Solution via HiPER-Ring! 4 Creating a redundant ring prevents communication loss should one of the backbone links fail. Redundant Link Click to continue

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

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 Redundant Link Watchdog Packets Ethernet Traffic Click to continue

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. Redundant Link ACTIVE Redundant Link ON STANDBY 7 Watchdog Packets Ethernet Traffic Click to continue

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. Redundant Link ON STANDBY 8 Click to continue

HiPER-Ring structure benefits Hirschmann’s HiPER-Ring Structure Optimized resiliency for today’s Ethernet networks Redundancy Manager standard in all Hirschmann’s RS2-XX/XX and MICE switches Fast learning in a ring is guaranteed by sending “clear address table” messages Max. reconfiguration time of 300 ms – reducing machine/production downtime Exchange of devices and network extension is possible during operation Simple and clear topology Up to 50 switches in a ring Plug & Play (with or without management) 9
