Meraki MX65 and Openwrt installation

I stumbled upon several Meraki MX65 conversions to Openwrt during my web surfing. The idea of having a smart openwrt device with more than 5 Ethernet ports which can also be like a managed switch is awesome.

Many claim that these can be booted using a POE switch. My 24 port POE switch delivers 60w of power on port 1 & 2 and 30w on all the remaining 22 ports.

Has anyone tried to power a Meraki MX65 using POE supplied power from another device? Specially, after they have been flashed to OpenWrt. Appreciate any comments.

WDYM??????

Sorry, mate. I meant has anyone tried to power them up using POE input on port 11/port 12 while the MX65 is in default / unclaimed state and then flash with OpenWrt using Lan port 1. The POE switch has no DHCP and so no IP can get assigned there tthrough the poe ports.
