Chapter 7 Controlling Lightweight Access Points

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.

Step 6 Click Apply to commit your changes.

Step 7 Click Save Configuration to save your settings.

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

Information similar to the following appears:

Cisco AP Identifier.............................. 1

Cisco AP Name.................................... AP1

...

PoE Pre-Standard Switch.......................... Enabled

PoE Power Injector MAC Addr...................... Disabled

Power Type/Mode.................................. PoE/Low Power (degraded mode)
