Information:

The LANCOM cellular router of the type 1780EW-4G is capable of operating with PoE via Ethernet port ETH-1, which makes the need to use an external power supply unit unnecessary.
  • LANCOM recommends the use of a PoE adapter or a PoE switch that complies with the standard IEEE 802.3at.

    Important notice: If this device is operated with power supplied via PoE as per the standard IEEE 802.3af, the LTE/4G module is not available for use.
  • Devices of hardware-release C that are supplied via PoE and additionally operated with a plugged-in external power supply unit continue to be powered by PoE.
