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
linking of rings via standby link), 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 is also enabled. If the device is intended to operate as the
redundancy manager, "Redundancy manager enabled" must also be set.
● Standby connection:
"Standby connection" must be "enabled" and the "Standby connection name" must match
the name of the partner device. You also configure the port with "Enable Standby Port
Monitoring".

Power supply
The pluggable transceivers are supplied with power via the SFP media modules in the modular
devices or via the SFP/SFP+/SCP/STP slots.
