Power over Ethernet (PoE) is categorised into 5 power classes which are supported accordingly
The Nexans GigaSwitch Series is offering PoE (PSE) functionalities. The systems are therefore in a position to supply devices
according to IEEE802.3at - Endpoint PSE mode "Mode A". For external power supply (PSE) of devices an operation volta-
ge of more than 46 VDC for IEEE802.3af and 50 VDC for IEEE802.3at is needed.
Note
In any case please check the correct pin assignment and the correct polarity of the PoE wiring at the terminal unit.

Warning!
Please check compatibility, proper pin assignment and polarity prior to and during putting the system
into operation in order to avoid any damage resulting from attaching incompatible equipment. The
maximum load of the individual ports and the overall load are limited. These limits have to be
observed in any case. Otherwise the connected units might be damaged or cannot be operated (see
Technical Data).
