PoE Configuration Example
Network requirements
Switch A is a Switch 4500 supporting PoE, Switch B can be PoE powered.
z The Ethernet 1/0/1 and Ethernet 1/0/2 ports of Switch A are connected to Switch B and an AP
respectively; the Ethernet 1/0/8 port is intended to be connected with an important AP.
z The PSE processing software of Switch A is first upgraded online. The remotely accessed PDs are
powered by Switch A.
z The power consumption of the accessed AP is 2,500 mW, and the maximum power consumption
of Switch B is 12,000 mW.
z It is required to guarantee the power feeding to the PDs connected to the Ethernet 1/0/8 port even
when Switch A is under full load.
