I have a 6509 that will be used to power many non Cisco Phones. My concern are the power supplies in the unit. I based my calculations on the actual power draw of the phones (4.4W). The supplies are fine for this, my question is whether the 6509 makes it power calculations from what is actually being used or whether it uses the allocated power. As the phones will not use CDP, they will register as Class 2 POE(802.3af)7W, therefore the power supplies are not big enough. If it does use the allocated power for the calculation, is there any way of limiting this?
