Chapter 3 Troubleshooting Autonomous Access Points

Low Power Condition for Autonomous Access Points

Configuring Power Using the CLI

Intelligent Power Management support is dependent on the version of software resident in the Cisco switch that is providing power to the access point. Each Cisco switch should be upgraded to support Intelligent Power Management. Until the software is upgraded, you can configure the access point to operate with older Cisco switch software using the following Cisco IOS CLI command:

[no]power inline negotiation {prestandard source injector {installed override H.H.H}}

(prestandard source indicates the Cisco switch does not support Intelligent Power Management. injector installed indicates a power injector is installed on the current switch port. injector override indicates a power injector is installed and the access point is configured to override the inline power checks. When you move the access point,

H.H.His used to specify the MAC address of the new switch port where the access point was moved. A MAC address of 0.0.0 is invalid.)

Caution When using the power inline negotiation injector override command, a power injector must always be installed to prevent a possible overload condition with an underpowered power source.

Note The power inline negotiation injector installed command will fail if CDP is disabled.

When using the p;ower inline negotiation injector override command, you must use a power injector to prevent possiblly overloading underpowered power sources.

You can use this Cisco IOS CLI command 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.

The access point was moved to a new Cisco switch port and a power injector is being used to supply sufficient power.

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 IEEE802.3af or IEC60950 for limited power sources.

Note After completing your configuration changes, you must remove the serial console cable from the access point.
