Configuring Ethernet Interfaces
You should carefully plan your switch power budget, enable the power monitoring feature, and make
Caution
certain not to oversubscribe the power supply.
When you manually configure the power budget, you must also consider the power loss over the cable
Note
between the switch and the powered device.
When you enter the power inline consumption default wattage or the no power inline consumption
default global configuration command or the power inline consumption wattage or the no power
inline consumption interface configuration command, this caution message appears:
%CAUTION: Interface Gi1/0/1: Misconfiguring the 'power inline
command may cause damage to the switch and void
oversubscribe the power supply.
It is recommended to enable power policing if the switch supports it.
Refer to documentation.
