NXA-ENET8POE Gigabit PoE Ethernet Switch
POE
The NXA-ENET8POE 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-802.3af compliant
devices.
The switch’s power management enables individual port power to be controlled within the switch 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 four power priority levels, critical, high, medium, or low. To control the power supply
within the switch’s budget, ports set at critical or high priority have power enabled in preference to those ports
set at low priority. For example, when a device is connected to a port set to critical priority, the switch supplies
the required power, if necessary, by dropping power to ports set for a lower priority. If power is dropped to
some low-priority ports and later the power demands on the switch fall back within its budget, the dropped
power is automatically restored. If PoE port priority is not configured, power is automatically allocated to the
port according its port number, that is, lower numbered ports are assigned a higher priority for power delivery.
