ANTMINER S3+ Discussion and Support Thread

[MCHouston]

dunno.. just tried it, no issues..

You configured the hostname that you tested on your router or on your miner?

I just tested from the WebGUI instead of the CLI, and interesting I do an error from the S3 seems it is aware of the IP address but its not completing the process. See below.

Have 2 S3+'s and one of them is making a clicking noise. Also on the inside of the miner just behind the exhaust fan a red light is on. I think it's on its way out.

Mine makes a similar noise during certain speeds, I think its one of the bearings on the fans that's going out soon.

my router that the s3s are connected to has ddr-wt on it.. i can setup a dhcp server with a static hostname..
but now i can see you can also do the same thing ON the s3.. in the hostname tab.

both works the same on my s3.

i just tried with my comcast xfinity router, and even tho it has a name, it wont resolve.


instead of using internal names, let me try what you are doing and try to dns a web address.


i think i might have found your problem.

the s3 has a built in dhcp server. in the s3 it is set to ignore outside dhcp. i turned mine off.. so it just uses the lan network dhcp server, but you having 100s of miners dont want to do that to each one lol.


to be honest, i would just use the IP and then static route it to your proxy computer.. skip names all together.. its not like you dont know 192.168.1.133 is your ip.

then just use the IP:PORT as your pool url.

You need to clean it (the fan's bearing) and put some lubricant

Hopefully that will fix it.  The good news is there is not a lot of moving parts so limit's it.   Hopefully lubricant will fix it.

Worst case should be new fan.  But since it sounds like it's still spinning I have a feeling lubricant chances are will do the trick.

Hi together,
I have already written this in the german section but hopefully somebody here can help me further with my little problem?
I got an used Antminer S3+ wich only comes up with a red flashing LED in front + shining red LED on the Board + 1 second spinning fans after powering on the PSU.
Inspired that this could be only a software/bootloader Problem I bought a USB-Serial adapter that arrives yesterday.

I plugged the rx/tx into the serial connection on the board from the antminer and the usb plug into my PC. After opening putty and power on the PSU I saw nothing but an empty putty window but the antminer started to work like normal  

I unplugged the usb-serial cable and the miner still works like usual but after powering down the PSU and restart it the miner comes up again only with the flashing red LED....
OK, plug again the rx/tx cables into the board and the usb into my PC = The miner starts like before to work!

Long story...but after all it seems to me that I have a ground problem and this little connection between the miner and my PC during start up of the miner solves it!
Have double check this with my Netbook and a second PSU: If I have only the connection between miner and Netbook nothing comes up but if I plug my netbook thru the wall the miner starts as usual.
Powered on this way the miner just works since yesterday evening
Can somebody give me a hint to solve this maybe little problem?
Thanks in advance!

When you say work like normal were you able to access the miner via IP?   Normally with the usb-serial you have to upload something to fix it, just plugging it in normally would not fix a boot problem.

As far ground problem can you go into a little more detail?  Are you talking about a electrical ground problem? Or what type of ground problem?

Yea you might have a bricked board. Check this out see if it works for you. https://bitcointalk.org/index.php?topic=889206.msg9902302#msg9902302

Not sure that is right ... looks like some kind of electrical issue. On the face of it, simply attaching to the serial port, to my mind, should not have an effect, but it clearly does here. So a stab in the dark would be that the serail connection establishes some kind of connection (electrical or otherwise) that spurts the rig to mining life.

I was about to ask what network settings you had, but I do not think that should matter in your instance. For completeness though, if you can access the S3 via the webUI, could you find out what the network settings are?

[luthermarcus]

Yea something seemed off in his case to me too. He shouldn't be able to connect without some kind of tinkering. My thinking was if he could connect to it through usb being the only thing that i was able to do when mine was bricked and everything was fine following the instructions there might be able to bring his back online without the usb. It's worth a shot if it doesn't work from there he could continue to diagnose.I would say something is wrong with the Ethernet port from there.

Plug in rx tx and ground for the instructions.

Were kinda waiting to hear more.  Just hooking it up and opening putty should not do anything to fix booting problem just by plugging usb to serial in.

Hey guys thanks that you try to help me!
I owe you some more details:
In the moment the miner is working since 22 hours together with my other miners. I have full access to him over the webinterface. Better to say: He is working 100% like any other miner, I have yesterday even changed the firmware to the latest from 9.1.2015.
If the miner is up one time, he is running well!
But the problem appears when Im turning off while unplug/turn off the PSU
Without the contact (say stand-alone) to my PC or Netbook (that must be powered from the wall !!! too) he is not be able to start again.
So to me as a non expert it looks like there is not enough Power-Ground. But this little connection from the serial ports with a other device powered by circuit is the little bit that is needed to start.
Once it started and the network led on the miner becomes green I can remove the serial connection and keepit running.

With less words: If the miner is running I can do all the things I want, even reboot, flashing new firmware,make changes in pooll settings...all works like it should be.
But to make the miner start up he needs the "starting help" otherwise there is only the red LED of death 
Any suggestions?

[pekatete]

Could you find out what your network settings are? Most likely nothing to do with it ... still could be something there.

[Chris_Sabian]

I still have my S3 running strong.

[Real-Duke]

The Network is set to a free fixed IP but even dhcp is possible. Im 100% sure it has nothing to do with the network adress, because if I power up the miner without the "Better Ground-Contact" he is simply not booting

"ok so are you running the Ethernet cable as well? do lights light up on ethernet cable?"(ignore this if not) or just usb tx/rx and gound? Your saying the serial gives it the proper conditions to run? What is the other device powered by circuit? How do you have this all connected can you provide pics? Bazaar and intriguing

On a normal day, I'd never have even let the thought cross my mind, however, your scenario is so peculiar I can not rule that out. Unless ofcourse there is a delamination of grounding contacts on your S3 control board somewhere (that may explain the serial grounding it).
On that note, I have to say if you have not tried with the network set to DHCP, then since you have a means of reviving it, I'd try that too just to be sure. (but that's all I can offer I am afraid)

[Real-Duke]

Yeah looks like this miner is unique  
Tomorrow evening Im going to remove all screws inside and hopefully I can see something whats maybe wrong with him. Until there Im sure he will do a pretty good job for me

on the custom dns, put 8.8.8.8

but i dont see anything wrong with these pics?

I would agree on dns changing. 

The weird thing is I think hes using a serial to usb on the controller to get it to work.    Real-Duke do you have the usb to serial plugged in for it to turn on?
