Requirements
■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.
