Power over Ethernet Specifications
The Power over Ethernet (PoE) is designed to extract power from a conventional twisted pair Category 5
Ethernet cable, conforming to the IEEE 802.3af Power-over-Ethernet (PoE) standard.
IEEE 802.3af allows for two power options for Category 5 cables.
The IEEE
802.3af-2003
standard allows up to 15.4 W of power the device. However, 12.95W is the
available power, as some power gets lost in the cable. The updated IEEE
802.3at-2009 (PoE+)
standard
allows up to 25.5 W (Max 34.2 W) of power the device.
PoE has advantages over conventional power in such places where AC powers cannot be reached or is
expensive to wire.

NOTE:
For proper activation of PoE, the Category 5 cable must be shorter than 100m and conform the
PoE standard.
NOTE:
When it is connected with non PSE, the power adaptor should be connected.
NOTE:
Connecting both PSE and power adaptor does not do any harm to the product. Disconnecting PSE
or power adaptor from device does not reboot the device as long as either one is connected to the
device.
