Power over Ethernet (PoE) 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.
Flash/File Commands (Cont.)
Command Function
boot system
This command
specifies the
image used to
start up the
system.
Syntax:
boot system [unit:] {boot-rom| config | opcode}: filename
The type of file or image to set as a default includes:
• boot-rom - Boot ROM (required).
• config - Configuration file (required).
• opcode - Run-time operation code (required).
• filename - Name of the configuration file or image name.
• unit - Specifies the unit number (required).
Default Setting: None
Command Mode: Global Configuration
Command Usage:
A colon (:) is required after the specified file type.

PoE Commands
Command Function
power mainpower maximum
allocation
Use this command to define a
power budget for the switch
(power available to all switch
ports).
Use the no form to restore the
default setting.
Syntax:
power mainpower maximum allocation <watts> [unit unit]
• unit - The switch unit in the stack.
• watts - The power budget for the switch. (Range: 36 - 800 watts)
Default Setting: 375 watts
Command Mode: Privileged Executive
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 sup-
plied power.
Example:
Console(config)#power mainpower maximum allocation 300
Console(config)#
