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.

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 4-69for 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)
