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:
[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
Caution
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.
Note
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:
•
•
•
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

inline power source —This message indicates the access point has been configured to override the
inline power checks and a power injector is installed.
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.
