Huawei AR150 series - Establishing the Configuration Task; Configuring the Poe Function Globally

3.3.1 Establishing the Configuration Task
Before configuring PoE, familiarize yourself with the applicable environment, complete the pre-
configuration tasks, and obtain the required data. This will help you complete the configuration
task quickly and accurately.
Applicable Environment
The AR150/200 can detect whether a device connected to it needs power supply and provide
power for it.
According to the actual requirements on the network, you can perform the following operations
by using commands:
l Set the maximum output power, power supply management mode, and reserved power of
a board.
l Set the backup mode of the PoE power supplies. Currently, the AR150/200 supports one
backup mode: 1+0, meaning that PoE power supplies are not backed up.
l Set the alarm threshold of the power consumption percentage.
l Enable the PoE function on an interface.
l Set the maximum output power and power supply priority of an interface.
l Power on and power off a PD on an interface.
l Set the power-off time range of a PoE interface.
l Configure a PSE to check the compatibility of PDs.
Pre-configuration Tasks
