Remote rig resetting tool with PoE and relay switch

My rigs are 30-35 minutes drive away from home and it's a pain in the ass to get there every time I need to restart the miner when it freezes or after power blackout some of them won't come back to live so I came up with an idea to build remote resetting tool with PoE and relay switch. Anyone can do this (this was my first soldering experience).. It is cheap and it is working.
[b]What I used:[/b]
1. Cheap PoE switch from ebay - 35$ 24 port powerdsine 6524

2. Relay switch from local electronic store 12v TIANBO - 0.76$

3.Ethernet cable crimped with RJ45 standard B on one side to connect to switch
(you don't need image for that)
4. Power/Reset SW cable 0.10$ without button (you don't need button neither)

I soldered one pair of RJ45 cable outgoing from switch on relay switch (full green and stripped brown, other contacts may also work)

On relay switch I also soldered Power SW cable with pins on other contacts which will later connect to motherboard

Then I connected pins to motherboard and connected RJ45 to PoE switch port

You have to write down which PoE switch ports are connected to which rigs to restart the miner you need to restart.
After all is set up next steps are simple, when rig freezes or won't come back after power blackout you need to connect to PoE switch's management IP and head to Port Configurations Enable/Disable section. By default you have all ports disabled, if you need to restart the rig which is connected to PoE switches port 1 you will enable it for about 3 seconds and disable. The miner will shut down, after that you will do this step again, enable the port for 3 seconds and disable, now rig will start up again and starts to mine.

I use H81 BTC and ASUS H81M-K motherboards, in case of H81 i never used HDMI dummys, after restarting them they power up and start the miner from startup folder, in case of H81M-k I'm using HDMI dummys because in most cases they need monitor to be plugged in.

I'm little bit sleepy now so if something is hard to understand or I did some technical mistakes feel free tell. I just wanted to share.

    pretty cool. What is the command on the switch to reset? I think you said you enable for 3 seconds and disable. What exactly is that doing and what are the commands on the switch?

    You actually log in via http, no command line is needed, it's simpler and everyone can do it, between enable and disable in last pic there's a button update and save, it takes appr. 3 seconds to do it.
