Only to keep things as together as possible, gotspring's misadventure with a RB5009 is posted here:
viewtopic.php?p=1061574
though it is not (yet) clear whether the power supply or the RB5009 unit he tested can be defective.
Even if Mikrotik's way to deal with PoE specifications appears more often then not "vague", I don't think that when they declare 150W for the router and 96W for the power supply a setup with only 40W+25W=65W can fail, if all the devices involved function correctly, it would be - more than deceiving advertising - a fraud.
It seems that the declared 802.3at support by Mikrotik is not fully-fully compliant with the standard, but at least in theory the 13W or so access points are well within the 15.4W of the 802.3af specs, so it cannot be an issue with negotiation between 802.3af and 802.3at power requirements.
Since the RB5009 model that supports PoE is a relatively new device there are not many reports on the field, let's wait and see if there are new similar reports of the standard setup being so much underpowered.
