Item Description
When the sum of the power consumption of all ports exceeds the maximum
power of PSE, the system considers the PSE as overloaded.
Power
The power priority for the HPE NJ5000 5G PoE+ switch cannot be changed. If
multiple PIs require power supply during power overload, the one with the
smallest ID takes precedence.
The device reserves 1 W power for each PI to prevent a PD from being powered
off because of power surge.
The maximum PI power of the HPE NJ5000 5G PoE+ switch is 17 W if it is
connected to an AT switch that supports IEEE 802.3at.
The maximum PI power of the HPE NJ5000 5G PoE+ switch is 5 W if it is
connected to an AF switch that supports IEEE 802.3af.
Configuring non-standard PD detection
There are standard PDs and nonstandard PDs. Usually, the PSE can detect only standard PDs and
supply power to them. The PSE can detect nonstandard PDs and supply power to them only if you
enable the PSE to detect nonstandard PDs.
