How much power does the AP need to come up on the controller?

Aruba Employee

Product and Software: This article applies to ArubaOS 3.3.2.x and later.

When the AP is first connected directly to the POE switch the switch should give 10 watts of power to the AP so that it can come up on the controller. The AP will not use the full 10 watts during normal operations. The actual power consumed by the AP will vary based on things like the configuration of the ARM and the number of radios used.

Example

The following multiple outputs are taken from the POE switch after the AP has connected directly to the switch.
