Power over Ethernet Commands
The commands in this group control the power that can be delivered to attached
PoE devices through the switch ports.
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
power mainpower maximum allocation < watts > [ unit unit ]
• watts - The power budget for the switch. (Range: 37 - 180 watts)
• unit - Specifies the stack unit. (Range: 1 - 8)
Default Setting
180 watts
Command Mode
Global Configuration
Command Usage
• Setting a maximum power budget for the switch enables power to be centrally
managed, preventing overload conditions at the power source.
• If the power demand from devices connected to the switch exceeds the power
budget setting, the switch uses port power priority settings to limit the supplied
power.
