Re: Antminers behaving erratically - electrical questions or advice please.
That does seem weird, I still can't figure out why you powered them down for the night. Maybe you just din't have them set where you wanted them.
So when running by itself on the PDU it powers up just fine. That tells me it's not an S9 issue. You say when both are connected they won't power on.
I'm not familiar with the Bitmain PSU's but my PSU's have their own power on switch. If you have these are you able to power on the PDU then power on the PSU's one at a time?
Your PDU should have plenty of room for what you are doing, and the fact that you see the PSU power on but not the S9 is peculiar. Have you made sure that in all the switching the PCI-e connectors are all secure and that your Ethernet is also secure?
As for the 1600W PSU you tried, I don't know the model but is that the output on 110V. Just covering my bases as I'm unfamiliar with it.

Thanks for thinking about it. I've come to some new conclusions.
Each miner works normally when alone on the PDU.
Therefore, either the PDU is not working properly, or the wall outlet is not working - as in not giving enough power. I think.
I'm going to try to get my electrician to take a look.
Thanks everyone!
Re: Antminers behaving erratically - electrical questions or advice please.
What PSUs are you using to power your devices?
I'm using Bitmain's PSU's right now.
Antminers behaving erratically - electrical questions or advice please.
Hello.
I am just getting 1 S9 and 1 A3 setup.
I am using a brand new subpanel in my garage. The electrician metered it after installation and voltage looked solid.
So there's a L6-30P receptacle to a 30 amp PSU.
Then I have 15A 14 AWG C14-C13 power cord going from PDU to both of my Bitmain PSU's.
Two PSU's are connected to 1 antminer s9 and 1 antminer a3.
So here's some of the funny stuff.
- They both ran fine for about 2 hours yesterday.
- The S9 dropped Hashrate for a while, but regained until I powered down for the night.
- Then this morning, both are plugged in and I power the PDU ON, the s9 won't boot, even though the PSU does. The A3 boots fine.
- Swapping PSU didn't seem to matter.
- Also the S9 would not recognize version, and no miner status page. I reset 3 times, and even tried plugging the s9 into an EVGA 1600 PSU on 110v. Still no hashing. No miner status page.
- THEN, I return the S9 back to it's Bitmain PSU on 220v, and turn the PDU on with the S9 ONLY running. (No a3 on) And then the S9 boots up and runs. Hashing normally with small drops occasionally over the past hour.
My suspicions is there may not be enough power coming in through the PDU? Or is it completely inside of the S9?
Should I get a multimeter kit? Would that matter what I tested? Where would I even begin testing? Can I get a readout of voltage provided by both antminers when they are plugged in?
There's so many variables and I am new at this. I don't know what to do, so thank you for any advice!

So if I get a miner into the cart, what about the controller thing? I am afraid of losing the 821, so I feel like checking out asap. What's the best strategy? Thanks and good luck to everyone!
Controllers are easy, it's just a Raspberry Pi3 and the image to burn on the disk is online from CanaanAh, that's easy. Thanks for the heads up
