So what happens if the switch undergoes a cold boot with 48 phones connected to it? The phones I am looking at only draw 7W based off the power brick. The phones support IEEE 802.af Class 2 and LLDP-MED, they do not support CDP
Does the switch providing/allocating 15W per port become an issue?
I think i may have found the answer to my question at the document referenced below.
"The switch uses the IEEE classification to learn the maximum power consumption of a powered device before powering it. The switch grants power only when the maximum wattage configured on the port is less than or equal to the IEEE class maximum. This ensures that the switch power budget is not oversubscribed. There is no such mechanism in Cisco prestandard powered devices. "
Am i correct in reading this as the switch can autosense the phone is a Class 2 7W device even before powering up the phones (regardless of cdp/lldp) so a switch with a 370W power supply can cold boot and power up 48 7W phones?
