Poe pass through but no data ns m2

Hello. I have installed openwrt firmware on my nanostation m2 wx version it works fine. I wanted to enable secondary poe in my nanostation so I put this command

“ uci show system.poe_passthrough”

And also this

“ uci set system.poe_passthrough.value=1
uci commit system”

After pasting the other nanostation m2 works but no internet!!
I gave Each nano different ip
Still no data
Any help please
