Connecting

Before connecting up and commissioning the device, read the information in the section
Safety instructions (Page 15)
NOTICE
Failure of the data traffic due to contamination of optical plug-in connections
Optical sockets and plugs are sensitive to contamination of the end face. Contamination
can lead to the failure of the optical transmission network.
Close unused optical sockets and plugs as well as pluggable transceivers and slots with the
supplied protective caps.
Remove the protective caps only immediately before you use the plug-in connection.
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").
