Poe Temperature-Protection - H3C s3100 series Command Manual

high: Sets the port priority to high.
low: Sets the port priority to low.
Description
Use the poe priority command to configure the PoE priority of a port.
Use the undo poe priority command to restore the default PoE priority.
By default, the PoE priority of a port is low.
When the available power of the PSE is too small, the PoE priority and the PoE management mode are
used together to determine how to allocate PoE power for the new PDs.
1) When the manual PoE management mode is adopted:
The switch will not supply power to the new PDs if the available power of the PSE is less than 19 W.
2) When the auto PoE management mode is adopted:
If a PD is plugged into the port with higher priority when the available power of the PSE is less than
19 W, the power supply to the port with the biggest number in the port group with the lowest priority
is turned off, so that a part of power is released for the new PD.
If the available power of the whole switch is less than 19 W and there is no port with low priority, the
port with the inserted PD cannot supply power.
