They provide:
•PoE+ ports: Support for IEEE 802.3af-compliant powered devices (up to 15.4 W PoE per port) and support for IEEE 802.3at-compliant powered devices (up to 30 W PoE+ per port). The maximum total PoE power in a 1RU switch is 1800 W.
•Cisco UPOE ports: Support for powered devices on all four Ethernet signal pairs (up to 60 W Cisco UPOE per port).
•Support for Cisco-enhanced PoE.
