Topic: Antminer s3 questions and trouble shooting (Read 932 times)

Yea they do not normally share parts on controller boards.  If it was a fan or something a lot  of them then would be ok to swap.

If it is truly a firmware problem that means most likely old user bricked the controller.  Most can be recovered with a serial to usb adapter and software.  Put in a ticket over at bitmain and they should help you through it https://bitmain.zendesk.com/hc/en-us/

I bought the miner knowing it had issues. I was hoping it was fixable. at 25 bucks no biggie right. The previous owner stated it was a controller board issue.

The PSU is a dell 750 watt server power supply the same ones I used for my other miners I pull this one off of a currently in use miner for the testing. I only ran this one miner on the power supply with nothing else hooked to it. I basically pulled the cables from one and pulled them into this one.

I haven't had a chance to mess with the firmware since I am unable to connect into it or see it on the network. I will try the 19.168.0.1 thru 254 later tonight and see if anything come up.

I know in the S1 to S3 upgrade kit they make you use the S1 controller and put it into the s3 and update the firmware from s1 to s3. I just don't know where to plug the third small cable in form the s1 controller that plugs into the has board. Since the S3 doesn't seem to have the extra cable.

I will update you if I can connect to it on the 192.168.0 net work later tonight or in the morning. i will also check out the links and see if there is something I havent already seen yet.

thanks for the information and help so far.

*Update* I have read both the links before unfortunately  and has given me nothing more than I already knew.. but thank you for trying. If I go by the led status I it says the miner is above 80C red light flashing and no fans spinning. But the temp is by far not above 30C because I barely just turned it on from shipping. Maybe it thinks it is to hot when it is not?  

I tried scanning the 192.168.0.1 thru 254 after changing my my computers ip address to the same and came up with nothing.

Any more suggestions.

I also found I could use the s1 controller but i am missing a back plane board that comes with the upgrade kit..

Not to my knowledge are S1 able to be used for S3 controller boards.  In perfect world that would be nice... but each model tends to have its own controller.

Have you tried to connect with something on 192.168.0.X network to see if it sees anything there?  Have you been doing anything with firmware? What PSU model are you using?  Did past owner say if it worked as 25 dollars I would assume something was wrong with it.

Official diagnostics are here: https://bitmain.zendesk.com/hc/en-us/articles/203341575-Hash-Board-Diagnostics and led status are in: https://bitmain.zendesk.com/hc/en-us/articles/200916329-S3-Manual

So I just picked up a s3 for 25 bucks, Trying to figure out what's wrong with it.

So I hooked it up to a good power supply, good as in it has been running another s3 of miners. So I know the power supply is good.

After turning the unit on. The fan do not start or try to spin at all.

The red light on the front of the unit is flashing at a normal speed of 1 flash per second and the green light on the on the ether net is flashing but has a pattern of 3 flashes one flash and almost like a dimming flash then start back to flashing 3 flashes again. There is also a red light on the control board around the 3.3v location or R42 on top of the controller.

I am unable to see the miner on my network by scanning from 192.168.1.1 to 192.168.1.255.

So I tried a factory reset. Held the button down for ten seconds and let off waited. While holding the reset button the green light goes out but the red light keeps flashing. The 3.3v red led on the control board stays the same.

After resetting the miner the green light never returns and I am still unable to see the unit on my network. I give the unit a power cycle and the same issues mention above come back.

Any suggestion.

Also I have a couple of s1's laying around think I could switch out the controller board and upgrade the firmware form s1 to s3?

Any help would be greatly appreciated.

Thanks,
Glen
