Haven't been able to find this anywhere but are the X90s able to utilize poe? If possible I'm looking to upgrade my network switch to take advantage of this... if not it's not the end of the world it'

Since the last firmware update I can no longer see any LAN connected devices on my network. I have a mixed setup of 2 X90s and 2 S4s, the LAN connections are only on one of the X90s via a switch. Note
