Manually Configuring Controller Information Using the Access Point CLI

You can use these controller CLI commands to inform the access point of the following:

•The Cisco switch does not support Intelligent Power Management but should be able to supply sufficient power.

•A power injector is being used to supply sufficient power and the Cisco switch does not support Intelligent Power Management.

Refer to Table 4-2for information on when to use these special CLI controller commands and the corresponding Cisco switch power command.

Caution If the access point receives power through PoE, the output current of the power sourcing equipment (PSE) cannot exceed 400 mA per port. The power source must comply with IEEE 802.3af or IEC60950 for limited power sources.

Table 4-2	Using CLI Power Commands
		CLI Commands
Power Source		Cisco Wireless LAN Controller	Cisco Switch
AC power module		None required	power inline never
Cisco switch that supports Intelligent Power		None required	power inline auto
Management1
Cisco switch that does not support Intelligent		config ap power pre-standard enable	power inline auto
Power Management1
Power injector2 used with a Cisco switch that		None required	power inline never3
supports Intelligent Power Management1
Power injector2 used with a Cisco switch that		config ap power injector enable	power inline never
does not support Intelligent Power
Management1
Power injector used with a non-Cisco switch		None required	–
802.3af compliant non-Cisco switches		None required	–

1.You should check the release notes for your Cisco power source to determine which Cisco IOS release supports Intelligent Power Management. Support for Intelligent Power Management might not be currently available for your Cisco power source.

2.Power injector must be AIR-PWRINJ3 or AIR-PWRINJ-FIB.

3.Cisco switches that support Intelligent Power Management always configure the use of a power injector at the switch.

Manually Configuring Controller Information Using the Access Point CLI

In a new installation, when your access point is unable to reach a DHCP server, you can manually configure needed controller information using the access point CLI. For information on how to connect to the console port, see the “Connecting to the Access Point Locally” section on page 4-11.

Note The CLI commands in this section can be used only on an access point that is not associated to a controller.
