PoE (Power over Ethernet) is a remote power supply function. With this function, the switch
can supply power to the connected devices over twisted-pair cables.
Some devices such as IP phones, access points (APs) and cameras may be located far
away from the AC power source in actual use. PoE can provide power for these devices
without requiring to deploy power cables. This allows a single cable to provide both data
connection and electric power for the device.
■
PSE
Power sourcing equipment (PSE) is a device that provides power for PDs on the Ethernet,
for example, the PoE switch. PSE can detect the PDs and determine the device power
requirements.
■
PD
Powered device (PD) is a device receiving power from the PSE, for example, IP phones and
access points. According to whether PDs comply with IEEE standard, they can be classified
into standard PDs and non-standard PDs. Only standard PDs can be powered via TP-Link
PoE switches.
