%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. 

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.

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:

[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.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.)

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.

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.

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.

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