PoE Configuration Example
Network requirements
As shown in Figure 5-2 ,
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.
