POE (Power over Ethernet)
PEO (Power over Ethernet) is a standard IEEE 802.3af. The standard provides
the capability to deliver both power and data over standard Ethernet cabling.
The standard provides 48 volts DC over two pairs of a four-pair cable at a
maximum current of 350 mA for a maximum load power of 15.4 watts,
although, after counting losses, only about 13 watts are available. 802.3af -
(PSEs) –”Power Source Equipments” can deliver their power on two ways, the
first is over the spare lines and the second is over the data lines. The power will
be connected to the (PDs) – “Powered Devices” just after an authentication
process against the PSEs passed and the maximum power consumption of the
PDs that can be connected to these PSEs must be less than ~12.9 - ~13Watt.
