If the software upgrade is not desired, you can configure the access point to operate in pre-standard compatibility mode and the access point automatically enters full power mode if these Cisco switches are detected in the received CDP ID field. When the access point determines that sufficient power is not available for full-power operation, one or both readios are deactivated and the Status LED turns amber to indicate low power mode (see Table 4-1). If your Cisco switch is capable of supplying sufficient power for full operation but the access point remains in low-power mode, your access point or your switch (or both) might be misconfigured (see Table 4-2. If your inline power source is not able to supply sufficient power for full operation, you should consider these options (see Table 4-2): • Upgrade to a higher-powered switch • Use a Cisco Aironet power injector on the switch port • Use the 48-VDC power module to locally power the access point Configuring Power Using Controller CLI Commands Intelligent Power Management support is dependent on the version of software resident in the Cisco switch that is providing power to the access point.

Troubleshooting Lightweight Access Points

Low Power Condition for Lightweight Access Points

Some Cisco switches that are capable of supplying sufficient power require a software upgrade to

support Intelligent Power Management. If the software upgrade is not desired, you can configure the

access point to operate in pre-standard compatibility mode and the access point automatically enters full

power mode if these Cisco switches are detected in the received CDP ID field.

When the access point determines that sufficient power is not available for full-power operation, one or

both readios are deactivated and the Status LED turns amber to indicate low power mode (see

Table 4-1

If your Cisco switch is capable of supplying sufficient power for full operation but the access point

remains in low-power mode, your access point or your switch (or both) might be misconfigured (see

Table 4-2

If your inline power source is not able to supply sufficient power for full operation, you should consider

these options (see

Table 4-2

•

Upgrade to a higher-powered switch

•

Use a Cisco Aironet power injector on the switch port

•

Use the 48-VDC power module to locally power the access point

Configuring Power Using Controller CLI Commands

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 use your controller to configure

the access point to operate with older switch software using these controller CLI commands:

config ap power pre-standard enable

where <

> is the access point name on the controller

config ap power injector enable <

> <switch port MAC address>

(where <

> is the access point name on the controller

and <switch port MAC address> is the MAC address of the switch port to which the

access point is connected)

Note

Refer to your controller documentation for instructions on using these commands.

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.

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.
