The first type, called the powered device or PD, receives power from the second type, called the power sourcing equipment or PSE. Powered devices include any Ethernet device capable of receiving power through a data port such as IP telephones, IP cameras, PDAs and tablet PCs. Power sourcing equipment, such as ProCurve switches with PoE support, must meet IEEE 802.3af specifications for voltage (47 to 57 volts DC) and wattage (up to 15.4 watts), with further limitations on devices that receive power. The ProCurve 8212zl is PoE-enabled to support both IEEE 802.3af compliant devices, as well as some pre-802.3af standard devices.
