Power over Ethernet
The NXA-ENET8-POE+ switch can provide DC power to a wide range of connected devices, eliminating the need for an additional
power source and cutting down on the amount of cables attached to each device. Once configured to supply power, an automatic
detection process is initialized by the switch that is authenticated by a PoE signature from the connected device.
Detection and authentication prevent damage to non-compliant devices (prior to IEEE 802.3af).
The switch's power management enables individual port power to be controlled within the switch's power budget. Port power can
be automatically turned on and off for connected devices, and a per-port power priority can be set so that the switch never exceeds
its power budget. When a device is connected to a switch port, its power requirements are detected by the switch before power is
supplied. If the power required by a device exceeds the power budget of the port or the whole switch, power is not supplied.
Ports can be set to one of three power priority levels, critical, high, or low. To control the power supply within the switch's budget,
ports set at critical to high priority have power enabled in preference to those ports set at low priority. For example, when a device
connected to a port is set to critical priority, the switch supplies the required power, if necessary by denying power to ports set for
a lower priority during bootup.
