The ECS4510-28P 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
(IEEE 802.3af or 802.3at).
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.
