Troubleshooting 1240AG Series Autonomous Access Points

Low Power Condition

The<

platform name>

indicates the Cisco platform detected by the access point. The

<MAC

address>

indicates the MAC address of the switch port.

Note

You need to upgrade the software on the Cisco switch to support Intelligent Power

Management or configure the access point for pre-standard compatibility.

•

%CDP_PD-4-POWER_OK: Full power - INJECTOR_CONFIGURED_OVERRIDE_SAFETY

inline power source —This message indicates the access point has been configured to override the

inline power checks and a power injector is installed.

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.

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 switch software using the following Cisco IOS CLI command:

[

]

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.H

is 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 power inline negotiation injector override command, you must use a power injector to

prevent possibly 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.
