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).
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. Take the following precautions to avoid
functional impairments:
● Clean the end face of field-assembled connectors carefully before connecting. No residues
of processing may remain on the connector.
● Only remove the dust caps of optical transceivers and pre-configured cables shortly before
connecting the cables.
● Close unused optical sockets and plugs as well as pluggable transceivers and slots with
the supplied protective caps.
