Switching power supply management mode, all PoE port under
electricity, ports in accordance with the new management model of
power supply to electricity.
When switch to static mode, if there is no port assignments power set,
the system automatically port configuration for power distribution,
support only 802.3 af equipment distribution of each port 15.4 W,
support at 802.3 equipment, distribution of each port 30 W.
8.2.3.
The POE port power priority
The user can configure the PoE switch port power supply priority.Priority from high to low in turn
is:Critical
、
High
、
Intermediate and Low
。
In automatic mode and energy-saving mode, high priority as
well as power supply port.At the time of PoE switch machine power shortage, low priority port first off
electricity, under the condition of the same priority, actual consumption power will be out of
electricity.The default priority of the interface are all low.
Same priority port, the new insert port, will not affect the already in the state of the power supply of PD
equipment power supply.Different priority of ports is not affected by this feature, high-priority ports can
preempt the low
priority.
For example, Set port 1 remote power supply for Critical priority, and close the POE priority, restore
the port priority as the default mode.
