■
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.
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.
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.
