Redundancy mechanisms
If you use redundancy mechanisms such as media redundancy "HRP" or "MRP" and/or redundant
linking of rings via a standby link, remember the following:
Open the redundant path before you insert a new device or replacement device in an operating
network. A bad configuration or attachment of the Ethernet cables to incorrectly configured
ports causes overload in the network and a breakdown in communication.
A device may only be inserted in a network and connected in the following situations:
• HRP / MRP
– The ring ports of the device being inserted in the ring were configured as ring ports.
– The required redundancy mode is also enabled.
– If the device is intended to operate as the redundancy manager, "Enable Ring
Redundancy" must also be set.
• Standby link
– Select "Enable Standby Master".
– The "Standby Connection Name" must match the name of the partner device.
– You must also configure the standby port.
You will find detailed information in the SCALANCE X-200 configuration manual.

Electrical connections
Note
Strain relief for the Ethernet cables
In order to avoid mechanical stress on the Ethernet cables and resulting interruption of the
contact, fasten the cables at a short distance from the connector using a cable guide or busbar.
