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).
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
• Only remove the dust caps of optical transceivers and pre-configured cables shortly
• Close unused optical sockets and plugs as well as pluggable transceivers and slots with

Notes on the PoE power supply
Incorrect power supply
The power of all connected power supply units must total the equivalent of a power source
with limited power (LPS limited power source).
If the device is connected to a redundant power supply (two separate power supplies), both
must meet these requirements.
Never operate the device with AC voltage or DC voltage higher than 60 V DC.
