Poe; 3- 11.1 Configuration - Vivotek AW-GEV-264A Series User Manual

3- 11 PoE

PoE is an acronym for Power Over Ethernet.
Power Over Ethernet is used to transmit electrical power, to remote devices over standard
Ethernet cable. It could for example be used for powering IP telephones, wireless LAN access
points and other equipment, where it would be difficult or expensive to connect the equipment
to main power supply.
The PoE detect function is follow the table
Stage
Detection PSE detects if the PD has the correct
signature resistance of 19–26.5 kΩ
Classification PSE detects resistor indicating power
range
Mark 1 Signals PSE is 802.3at capable. PD
presents a 0.25–4 mA load.
Class 2 PSE outputs classification voltage again
to indicate 802.3at capability
Mark 2 Signals PSE is 802.3at capable. PD
presents a 0.25–4 mA load.
