Power over Ethernet
The GEP-1061 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.
