NOTICE
Commissioning devices with redundancy mechanisms
If you use redundancy mechanisms ("HSR" media redundancy or "MRP" and/or redundant
coupling of rings over standby coupling), open the redundant path before you insert a new
or replacement device in an operational 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:
• HSR/MRP:
• Standby coupling:

WARNING
The ring ports of the device being inserted in the ring were configured as ring ports. The
required redundancy mode must also be enabled (see "Configuration Manual
SCALANCE X-300 / X-400", section "X-300 Ring Configuration"). If the device is
intended to operate as the redundancy manager, "Redundancy manager enabled" must
also be set.
"Standby connection" must be "enabled" and the "Standby connection name" must
match the name of the partner device. You will also need to configure the port with
"Enable Standby Port Monitoring" (see "Configuration Manual SCALANCE X-300 /
X-400", section "X-300/X-400 Standby Mask").
