Ring Redundancy

Note: As an alternative to using software to configure the HIPER-Ring, with
devices RS20/30/40 and MS20/30 you can also use DIP switches to enter a
number of settings on the devices. You can also use a DIP switch to enter a
setting for whether the configuration via DIP switch or the configuration via
software has priority. The state on delivery is “Software Configuration”. You
will find details on the DIP switches in the “Installation” user manual.
Parameter Meaning
Ring port X.X operation Display in “Operation” field:
active: This port is switched on and has a link.
inactive: This port is switched off or it has no link.
Ring Manager Status Status information, no input possible:
Active (redundant line): The redundant line was closed
because a data line or a network component within the ring failed.
Inactive: The redundant ring is open, and all data lines and
network components are working.
Ring Manager Mode If there is exactly one device, you switch the Ring Manager
function on at the ends of the line.
Ring Recovery The settings in the ”Ring Recovery“ frame are only effective for
devices that are ring managers.
In the ring manager, select the desired value for the test packet
timeout for which the ring manager waits after sending a test
packet before it evaluates the test packet as lost.
Standard: test packet timeout 480 ms
Accelerated: test packet timeout 280 ms
Note: The settings are especially meaningful if at least one line in
the ring consists of a 1,000 MBit/s twisted pair line. The
reconfiguration time after connection interruption existing due to
the reaction characteristic of 1,000 MBit/s twisted pair ports can
thus be accelerated considerably.
Information If the device is a ring manager: The displays in this frame mean:
“Redundancy working”: When a component of the ring is down, the
redundant line takes over its function.
“Configuration failure”: You have configured the function
incorrectly, or there is no ring port connection.
