5.1 Commissioning
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:
• With standby link:
For further information, refer to the configuration manuals (Page 5).
