This is likely a noob question, but how does one SSH into a miner?

Thanks for the help. Will try this.

I have a copy of the firmware, Bitmain emailed it to me in a support ticket. And I've tried reflashing it to no avail.

But I will try to do this when powering up only the main board and let you know. Thanks again.

Nevermind I just re-read that. I see what you mean about the PSU not being enough.

We do have a Bitmain Apw PSU, but we're running 120V.

How would you recommend utilizing 1 Bitmain PSU and 2 850W PSUs to power this thing at 120v?

We're using 2x 850W power supplies.

I can't even get to the screen to adjust frequency, with everything blank on the main screen.

Hi guys, can use some opinions on why my A3 is not working. Situation:

I purchased a few A3 and set them up at home. Had a hell of a time figuring out the "No Socket Connection" errors until I determined that SiaMining was the only thing that got it to run. At home, I run 240v and they were powered on one Bitmain APW3 PSU. Ran beautifully.

I sold one to a friend. He set it up with the following:

120V
2 850W power supplies (1 powering 2 boards, the other powering the main control board and the 3rd board)

No matter what we did, we could not get his to mine. We tried all of the following:

1. Reflashing the firmware.
2. Giving the miner a static IP address on the network
3. Multiple reboots
4. Multiple Resets to default settings.
5. Unplugging and re-powering

After the static IP failed to work, I tried to revert it to a DHCP Ip address, and here's where we are now stuck.

Now, the miner shows me nothing on the General Overview Page. Everything on that page is completely blank for the System fields, and all of the Memory status bars are at 0. I tried re-flashing the firmware again, and still everything is blank, and I cannot even click on any other tabs within the antminer menu. I cannot click on Configuration, or Status, or Network.

He lives in a colder climate and just got the machine yesterday, so I told him to unplug it for the night and let it get to room temp indoors before we try again. As we were troubleshooting, the A3 was on high speed with the fan, so I am wondering if it was overheated after being delivered in the cold.

Any advice on what else to try is extremely appreciated.
