Further notes

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).

In areas subject to the NEC or CEC:

Safety notice for connectors with LAN (Local Area Network) marking

A LAN or LAN segment, with all its associated interconnected equipment, shall be entirely

contained within a single low-voltage power distribution and within a single building. The

LAN is considered to be in an "environment A" according to IEEE802.3 or "environment 0"

according to IEC TR 62102, respectively. Never connect directly to TNV-circuits (Telephone

Network) or WAN (Wide Area Network).
