WARNING
Commissioning devices and replacement devices
If you use redundancy mechanisms (HRP/MRP ring redundancy and/or redundant coupling
of rings with standby), 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:
•
With HRP/MRP:
–
Ring redundancy must be activated
–
The mode must be selected correctly.
–
The ring ports of the device being inserted in the HRP/MRP ring must be configured
as ring ports.
•
With standby link:
–
The standby connection must be activated.
–
The "Standby Connection Name" must match the name of the partner device.
–
The port must be configured as a standby port.
For further information, refer to the configuration manuals (Page 5).
