Sharing power in a 3850 stack

Level 1

I have 4) 3850 switches in a stack with stack power and sharing mode. All the POE devices are on switch 4 and it's almost out of POE power. Can one of the other switches in the stack provide extra POE power for switch number 4? Switch 4 has 30.6 watts remaining. Switch 1, 2, and 3 all have over 700 watts remaining. I know I can move devices from switch 4 to the other switches, but is there a way to send power from switches 1, 2, or 3 to switch 4?

 

Thanks

"Can one of the other switches in the stack provide extra POE power for switch number 4?"

From what I reading, the answer should be yes.

Do know, on the predecessor 3750-X, its StackPower had an amperage limitation on the StackPower cables.  I couldn't find whether there's a similar limitation for the 3850.
