Ring Redundancy
If you used the DIP switch to activate the function of HIPER-Ring, RSTP is
automatically switched off.
 Now you connect the line to the ring. To do this, you connect the 2 devices
to the ends of the line using their ring ports.
The displays in the "Redundancy Manager Status" frame mean:
– "Active (redundant line)": The ring is open, which means that a data
line or a network component within the ring is down.
– "Inactive": The ring is closed, which means that the data lines and
network components are working.
The displays in the "Information" frame mean
– "Redundancy existing": One of the lines affected by the function may
be interrupted, with the redundant line then taking over the function
of the interrupted line.
– "Configuration failure": The function is incorrectly configured or the
cable connections at the ring ports are improperly configured (e.g.,
not plugged into the ring ports).
Note: If you want to use link aggregation connections in the HIPER-Ring
(PowerMICE and MACH 4000), you enter the index of the desired link
aggregation entry for the module and the port.
