We have a bunch of these AP's in use for Spacenet and the tenants/students network. They're powered via Power over Ethernet in a artificial way: an injector at the patch panel, and a splitter at the AP. The advantage of this is at least that we don't need adapters at the AP's, but the flipside is the cable spaghetti at the patch panel side.
The manual can be found here. They have a web interface, and the user is 'admin' and the password is the usual. ;)
