Setting a Switch Power Budget

A maximum PoE power budget for the switch (power available to all switch ports)
can be defined so that power can 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.
Command Attributes
Power Allocation – The power budget for the switch. If devices connected to the
switch require more power than the switch budget, the port power priority settings
are used to control the supplied power. (Range: 37 - 375 watts; Default: 375 Watts)
Web – Click PoE, Power Config. Specify the desired power budget for the switch.
Click Apply.
