UltraWave Product Guide
Power over Ethernet
Silver Network based UltraWave pairs using Ethernet communications have the option of using
Power over Ethernet. To use this powering option requires a PoE class 3 switch that is located
within 100 m (328 ft.) of the transmitter/receiver, and minimum Category 5 network cable. Power
over Ethernet is supplied to the Network Interface card (NIC) and the power output on the NIC is
connected to the power input on the transmitter/receiver. Each unit receiving PoE requires an
earth ground connection.
