POE/POE PROFILE CONFIGURATION

28 GUIDE

PoE Configuration	Power over Ethernet (PoE)-enabled devices use 10BASE-T, 100BASE-TX and
	1000BASE-T twisted pair cables to supply power to powered devices (PD) and
	implement power supply and data transmission simultaneously.

Requirements

Switch B AP AP

■Switch A is a Switch 5500 supporting PoE and Switch B can be PoE powered.

■The Ethernet 1/0/1 and Ethernet 1/0/2 ports of Switch A are connected to Switch B and an Access Point (AP) respectively; the Ethernet 1/0/8 port is intended to be connected with an important AP.

■The PSE processing software of Switch A is first upgraded online. The remotely accessed PDs are powered by Switch A.

■The power consumption of the accessed AP is 2,500 milliwatts, and the maximum power consumption of Switch B is 12,000 milliwatts.

■It is required to guarantee the power supply to the AP connected to the Ethernet 1/0/8 even when Switch A is under full load.
