Configuring Power over Ethernet
•
Override—This option allows the access point to operate in high-power mode without first
verifying a matching MAC address. It is acceptable to use this option if your network does not
contain any older Cisco 6-Watt switches that could be overloaded if connected directly to a 12-Watt
access point. The advantage of this option is that if you relocate the access point, it continues to
operate in high-power mode without any further configuration. The disadvantage of this option is
that if the access point is connected directly to a 6-Watt switch, an overload occurs.

Using the CLI to Configure Power over Ethernet
Using the controller CLI, enter these commands to configure and view PoE settings.
•
If your network contains any older Cisco 6-Watt switches that could be accidentally overloaded if
connected directly to a 12-Watt access point, enter this command:
config ap power injector enable {Cisco_AP | all} installed
The access point remembers that a power injector is connected to this particular switch port. If you
relocate the access point, you must reissue this command after the presence of a new power injector
is verified.
Note
Make sure CDP is enabled before issuing this command. Otherwise, this command will fail.
See the
“Configuring Cisco Discovery Protocol” section on page 4-69
for information on
enabling CDP.
•
To remove the safety checks and allow the access point to be connected to any switch port, enter this
command:
config ap power injector enable {Cisco_AP | all} override
It is acceptable to use this command if your network does not contain any older Cisco 6-Watt
switches that could be overloaded if connected directly to a 12-Watt access point. The access point
assumes that a power injector is always connected. If you relocate the access point, it continues to
assume that a power injector is present.
•
If you know the MAC address of the connected switch port and do not wish to automatically detect
it using the installed option, enter this command:
config ap power injector enable {Cisco_AP | all} switch_port_mac_address
•
To view the PoE settings for a specific access point, enter this command:
show ap config general Cisco_AP
