Configuration Example Networking Requirements
The Ethernet1/0/1 and Ethernet1/0/2 ports of the Switch 4500 PWR are connected
with a PD and an access point (AP) respectively.
The Ethernet1/0/24 port is intended to be connected with an AP. The PSE
processing software of the Switch 4500 PWR should be first upgraded online. The
remotely accessed PDs should be powered by the Switch 4500 PWR. The power
consumption of the AP that has already been connected with Ethernet1/0/2 is
2500 mW, and the power consumption of the PSU is 12000 mW. This is required
