Chapter 4 Service Configuration
Guidelines
When the sum of the power that a port requires and the power that the current system
consumes is larger than the maximum output power, power supply cannot be provided for
this port until a power preemption event occurs. Due to the event, ports with lower priorities
will be disabled and power supply will be provided for the port. During power supply, if the
device’s output power is larger than the maximum output power due to power consumption
changes, an alarm is activated. If the device’s output power is larger than the sum of the
maximum output power and the threshold, the port with the lowest priority will be powered
off.
Example
The following example sets the maximum output power and protection threshold to 400W:
zte(cfg)#set poe power maxvalue 400
