PoE Configuration Example

Networking requirements

Switch A is an S3100 series Ethernet switch supporting PoE, 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 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

The power consumption of the accessed AP is 2,500 mW, and the maximum power consumption

of Switch B is 12,000 mW.

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.
