Configuring Power Using Controller Cli Commands - Cisco 1130AG - Aironet - Wireless Access Point Hardware Installation Manual

Chapter 4 Troubleshooting 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
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
If your inline power source is not able to supply sufficient power for full operation, you should consider
these options (see

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:
1) config ap power pre-standard enable <ap>
2) config ap power injector enable <ap> <switch port MAC address>
Refer to your controller documentation for instructions on using these commands.
Note
You can use these controller CLI commands to inform the access point of the following:
•
•
If the access point receives power through PoE, the output current of the power sourcing equipment
Caution
(PSE) cannot exceed 400 mA per port. The power source must comply with IEEE 802.3af or IEC60950
for limited power sources.

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
where <ap> is the access point name on the controller
(where <ap> 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)
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.
