13 Power over Ethernet Commands
The commands in this group control the power that can be delivered to attached
PoE devices through RJ-45 ports 1-24 on the ECS4120-28P.
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.
power mainpower
maximum allocation
This command defines a power budget for the switch (i.e., the power available to all
switch ports). Use the no form to restore the default setting.
Syntax
