1.1 Overview

Power over Ethernet (PoE) is a remote power supply function. With this function, the switch
can supply power to the connected devices over twisted-pair cable.
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 to devices.
IEEE 802.3af and 802.3at are both PoE standards. The standard process of PoE power
supply contains powered-device discovery, power administration, disconnect detection
and optional power-device power classification.
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.
1.2 Supported Features
PoE Power Management
PoE Power Management is used for users to manage the power the PoE switch supplied.
The PoE switch allocates the power to the PDs according to your configurations.
Time-Range Function
The time-range function is used to set the power-on and power-off time range to save
energy according to your actual use.
