Ring Redundancy
The displays in the "Redundancy Manger 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 can
fail, whereby the redundant line will then take over the function of the
failed line.
– "Configuration failure": The function is incorrectly configured or there
is an error in the ring port connection.
Note: When you use the DIP switch to switch from a normal port to a ring
port, the device makes the required settings for the pre-defined ring ports in
the configuration table. The port which has been switched back from a ring
port to a normal port keeps the ring port settings (transmission speed and
mode). Independently of the DIP switch setting, you can still change all the
ports via the software.
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 aggre-
gation entry for the module and the port.
