Got an alert from my S9 that it was down and when I went to check on it, discovered that all 3 of my miners seem dead. Power is up/good:

l3+ powers on, no status lights on the hasboards, 2 red leds near one of the hashboard connectors
s9 powers on, no status lights on the hashboards.  leds on the controller are all green.  One hashboard briefly flickers red but then nothing.
doge mini powers on but red status light on the front (Alas, I was going to unplug is yesterday to sell it, but didn't get around to it)

No web response for any of them.

I'm pretty sure I'm well and truly f*cked.  Even at used prices, none of them have even paid for themselves yet :(

Any advice on what to do next?  I'm pretty sure it must have been a power surge, everything is plugged into a bare PDU.

shut them all off.

wait 1 hour


only turn back the s9 in 1 hour.

do it with just the controller connected ie unplug the 9 power jacks to the 3 hashboards.

let us know if you can find the controller on your internet/router

Yeah, no network, even though I have network status lights blinking and the controller board LEDs are all green.

Is your network switch / router gear broken?

No, I am able to ping the wireless hub and a computer connected to the switch on the hub.

Have you tried factory default reset for one S9 as a test?

I'll try reloading the OS from an SD card and see if I get anywhere.

Let's just focus on the S9s, try not to mention the other gears, or else your topic will be moved to the alt section and it's a spam land.

The first thing I would suspect when more than 1 gear start acting weird at the same time would be the network setup, the second thing would be the PSUs, get a cheap multimeter to confirm you are getting 12v on the DC output or use a PC's PSU to test the S9, make sure it's at least 400w and unplug 2 hash boards (keep only 1 hash board).

Usually, the miner itself isn't affected by power-related issues, the PSU will take the hit and die, so hopefully, that will be the case for you.

How many doors you got in home? You can always use them as door stoppers.

Mining is no joke. If you somehow manage to make them work, hopefully you'll sell them and buy the thing you mine instead. You probably realized that mining makes no sense if you are a small time miner.

I have pretty much enough free power for a small 6000 watt farm.  Not going to quit yet.  It's more of a hobby than anything at this point and it's older equipment that would be paid for in 6 months or so if I can keep them running.

Back in the saddle.  Yes, it was a network issue, the crappy netgear switch I was using has a bunch of dead ports, I was testing on one of the good ports.  Thanks again for the advice everyone.

I'm glad that I remembered mentioning the possibility of networking gear being faulty and that you got it all running ok again! :)
