3Com 4210 PWR Configuration Manual page 347

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 powered by Switch A.
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.
