Network requirements

z As shown in Figure 1-4, GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 are connected to IP

telephones.

z GigabitEthernet 1/0/11 is connected to AP whose maximum power does not exceed 9000

milliwatts.

z The power supply priority of IP telephones is higher than that of AP; therefore, the PSE supplies

power to IP telephones first when the PSE power is overloaded.
