PoE Configuration Example
Network requirements
The device provides power supply for PDs through PoE interfaces.
z GigabitEthernet 1/0/1 and GigabitEthernet 1/0/2 are connected to IP telephones.
z GigabitEthernet 1/0/11 and GigabitEthernet 1/0/12 are connected to access point (AP) devices.
z The power priority of GigabitEthernet 1/0/2 is critical.
z The power of the AP device connected to GigabitEthernet 1/0/11 does not exceed 9,000
milliwatts.
