PoE (Power over Ethernet)

"Power over Ethernet" (PoE) supplies power and transmits data simultaneously
and safely over the same ETHERNET cable, eliminating the need for a separate
power supply.
"Power over Ethernet" (POE) is an ETHERNET network technology defined in the
IEEE 802.3af (PoE) und 802.3at (PoE+) standards.
If the IEEE 802.3at standard is supported, a higher current can be transmitted via
the ETHERNET cable.

Total
Special equipment is required for PoE (PSE = "Power Sourcing Equipment") and
subscribers (PD = "Powered Device").
The PoE description and performance classes are available in the appendix (see
Section "Appendix" > "PoE Performance Classes").
PoE can be realized in 2 operating modes.
Operating Mode A
In this operating mode, the supply voltage is modulated on the data lines
("phantom power").
Operating Mode A can be used with the following transmission standards:
• 10BASE-T
• 100BASE-TX
• 1000BASE-T
