Safety when connecting up
Safety notices
When connecting up the device, keep to the safety notices listed below.
WARNING
Safety notice for connecting with a LAN ID (Local Area Network)
A LAN or LAN segment with all the interconnected devices should be contained completely in
a single low voltage power distribution in a building. The LAN is designed either for
“Environment A” according to IEEE802.3 or "Environment 0" according to IEC TR 62102.
Do not connect any electrical connectors directly to the telephone network (telephone network
voltage) or a WAN (Wide Area Network).

Notes on commissioning
Note
Commissioning devices with redundancy mechanisms
If you use redundancy mechanisms ("HRP" 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:
● HRP/MRP:
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 coupling:
"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").
