Power over Ethernet
802.3af PoE or 802.3at PoE+ delivered over any of the RJ-45 network ports within the listed power budgetsSwitches support 802.3af, 802.3at, and Cisco pre-standard (legacy) PoE with maximum power of 30 W per port.
This applies to the following PoE-enabled models; the maximum number of ports providing PoE power simultaneously is determined by the total PoE budget for the switch listed as below:
PoE Power Budget: 195 W
Number of Ports That Support PoE: 24
Pre-standard PoESupport Cisco Pre-Standard PoE
Intelligent PoE power managementSupport the granular power negotiation with CDP/LLDP communication with PD devices after IEEE classification
