determined by
reserved power of each port or power devices.
Allocation
: users can allocate the amount of power that
each port reserves. The allocated/reserved power for each
port/power device is specified in the Maximum Power field.
Class
: each port automatically determines how much power
to reserve according to the class the connected power
device belongs to, and then reserves the power accordingly.
Four different port classes are available, including 4, 7, 15.4,
and 30 Watts. In this mode, the maximum power field will
gray out.
LLDP-MED
: this mode is similar to the
Class
mode expect
that each port determines the amount power it wants to
reserve by exchanging PoE information using the LLDP
protocol. If no LLDP information is available for the port, the
port will reserve power using the
Class
mode. In this mode,
the maximum power fields will gray out.
In all of the abovementioned modes, if a port uses more
power than the reserved power for the port, the port is shut
down.
Power Management Mode
There are two modes available when configuring when to
shut down the port:
Actual Consumption
: the ports are shut down when the
actual power consumption for all ports exceeds the amount
of power that the power supply can deliver or if the actual
power consumption for a given port exceeds the reserved
power of that port. The ports are shut down according to port
priority. If two ports have the same priority, the port with the
highest port number is shut down.
Reserved Power
: the ports are shut down when total
reserved power exceeds the amount of power that the power
supply can deliver. The port power will not be turned on if the
power device requests more power than available from the
power supply.
