All my 4300-MP switches wth 1400w power supplies show up  in the power budget as 1100w pwr supplies.

My guess.. The extra power is needed for the switch and it only offers 1100w to the poe controller ?!?!

Can someone confirm this is do to needed power by the base system or is this a possbile bad power formula  ?

 

Will be happy to post a Jtac but have found sound advice / info forums and well worth me going down the rabbit hole to

look deeper.

1400W PSU runs at 1100W if plugged into low line voltage (115V). To get 1400W you need to use 208-240V.
