Configuring PoE PoE Note： Only T1600G-28PS and T1600G-52PS supports PoE feature.. 1 PoE 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. Configuration Guide 488
