H3C Technologies H3C MSR 50 - Manual (Page 181)

• The power supply priority of GigabitEthernet 3/2 is critical. If 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.
• The power of the AP device connected to GigabitEthernet 5/2 does not exceed 9000 milliwatts.

Verifying the configuration
After the configuration takes effect, the IP telephones and AP devices are powered and can operate
correctly.
