Networking requirements
As shown in Figure 62-1 , Switch A supports PoE, Switch B can be PoE powered.
z
The GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 ports of Switch A are connected to Switch B
and an AP respectively; the GigabitEthernet 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 GigabitEthernet 1/0/8 port
even when Switch A is under full load.
