Wireless Access

Hi, 

i was reading through the datasheet of AP205H. 

http://www.arubanetworks.com/assets/ds/DS_AP205H.pdf

Came to know of the intresting feature, that the USB port on the AP can be used to charge a battery power-bank or a mobilephone, and is capable of supplying 1A/5V power which is actually good for charging mobile phones. 

How to enable the USB port to be used for device charging purposes?

Will be powered up by any mode, to have that feature. (by External power or by POE af or at anything)

Please advise, what things to be noted to use that feature? and what configuration to be enabled so that the USB port on the AP is always alive to have some mobile phone device or a power-bank to be charged up(just like a USB port on a PC) 

Thank you for response. Understand it will work automatically if powered up by a external power adaptor or by 802.3at. 

Now if the AP is powered to 802.3af port. Will turning on the configuration "AP USB Power override" in the AP system profile work? 

Thank you all. That clears all my doubts. 

Then what is the use case of enabling the USB port( by turning on the option "AP USB Power override" in the ap system profile), when the AP is powered by 802.3af POE?
