PoE Configuration Example
Network requirements
As shown in Figure 1-2 ,
z
The device is equipped with two PoE-supporting cards, which are inserted in Slot 3 and Slot 5
respectively. The PSE IDs are 4 and 6.
z
Allocate 400 watts to PSE 4, provided the default maximum power to PSE in PSE 6 can meet the
requirements.
z
GigabitEthernet 3/0/1 and GigabitEthernet 3/0/2 are connected to IP telephones.
z
GigabitEthernet 5/0/1 and GigabitEthernet 5/0/2 are connected to AP devices.
z
The power supply priority of GigabitEthernet 3/0/2 is critical. When a new PD results in PSE power
overload, the PSE does not supply power to the new PD according to the default PoE interface
power management priority policy.
z
The power of the AP device connected to GigabitEthernet 5/0/2 does not exceed 9000 milliwatts.
