Power Over Ethernet (PoE) Settings
Overview
This 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-802.3af compliant devices.
The switch’s power management enables total switch power and individual port power to be controlled within
a configured 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 allocated 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 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.
