Table

PoE Standards, Types, Classes, and Watts

PoE Standards, Types, Classes, and Watts reference with assumptions and boundary notes.

Reference boundary

Low-voltage power reference only. It does not design a data cabling system or approve device compatibility.

Reference table

Compare common Power over Ethernet type and class labels by approximate power levels.

Reference basis uses rounded IEEE 802.3 PoE type and class power relationships.

Type 2PoE+4up to about 25 W
Type 3PoE++5 to 6up to about 51 W
Type 4High-power PoE7 to 8up to about 71 W
