Operating in very remote location - power supply

I am operating a FR24 box in a very remote location. I have successfully had the feed running. We are on generator power. Every time the power is interrupted, the feed goes offline. There is also a large delay before it shows online again, so difficult to assess which startup procedure is optimal.

Can anyone tell me the best sequence for re-starting:
a. Get the power back on, confirm the lights are all functioning correctly, then connect the Ethernet cable? or
b. Connect the Ethernet cable to the router, then apply power to the unit?

(or c. it doesn't matter which way you do it!)

Thanks in advance
