SCALANCE X-300

The redundancy manager function is enabled by the SELECT/SET button or by a setting in
the software. For more detailed information, refer to the configuration manual
"SCALANCE X-300 and SCALANCE X-400 Industrial Ethernet Switches".
In contrast to the ring ports of the redundancy clients, the ring ports of the redundancy
manager are disconnected when the network is operating problem-free. The IE Switch X-300
operating in the role of redundancy manager mode monitors the connected bus over its ring
ports and switches the ring ports through if there is an interruption on the connected bus; in
other words, it restores a functioning bus over this substitute path. Reconfiguration is
achieved within 0.3 s. As soon as the problem is eliminated, the original topology is restored;
in other words, the ring ports in the redundancy manager are disconnected from each other
again.
In a ring with media redundancy, only one device can operate as the redundancy manager.
Ring ports
An electrical ring with redundancy manager can be set up via the RJ-45 connectors that
allow attachment of electrical (twisted pair) connections (10, 100 and/or 1000 Mbps). The
SCALANCE X310FE is an exception to this. This device only allows attachment of electrical
(twisted-pair) connections at 10 or 100 Mbps.
The use of the IE Switch X-300 in an optical ring (1000 Mbps, with SCALANCE X-300EEC
100Mbps) with a redundancy manager is also possible with the exception of the devices
SCALANCE X310 and SCALANCE X310FE.
You can configure which ports take on the function of ring ports individually. The following
table shows the factory defaults for the ring ports.
