Thank you for your contribution to this discussion, Cassey.  Like I said, I'm not a specialist.  I used YouTube videos to help me learn what I wanted to do with mine.

Bitmain sent an email with the following info included. So you should email them with the info below.  Good luck.

If you did not receive a coupon and you’d like to purchase a miner with a coupon, please do not hesitate and send an email to [email protected] in the below format. We will manually assign the coupon to your account. You can only use one coupon per miner.

Static or dynamic (DHCP) shouldn't matter - networking routing, firewalls, etc. will.

If you can connect to the IP address displayed on the unit while on the same subnet, BitMain has delivered.  If the unit is not displaying an IP Address, then you either don't have dhcp running on that subnet, or the unit does not have a valid network connection (bad cable perhaps?), or the unit is broke - in decreasing order of probability.

Received the e-mail yesterday that all prior BitMain customers should have received coupons towards purchasing several BitMain products, including the S4.

I had purchased (2) S3s back in September directly from BitMain - so believe I qualify as a prior customer.

When did people start receiving these coupons?  I ordered my S4 on November 14th and wonder if I should be pushing for a rebate due to the failure of them giving me one?

I could be wrong on this:  I would believe your network the S4 is connected to would need to be set up for DHCP and you know the address assigned to it [whether it was assigned automatically or manually as in my case] in order to connect to your S4.

Bitmaintech is not responsible for what you do with your network set up and whether you want to connect remotely or not.  They are only responsible for the unit.  If the unit had problems connecting to it remotely, THEN I could see bitmaintech coming into play.

However, I honestly believe you need to set up your S4 to connect to a DHCP network NOT static in order to connect to it remotely within that network.

I'm not a network specialist.  I'm just telling you how I have mine setup with my Airport Extreme Base Station from Apple.

This is a software problem. Sometimes i have it too, after power failure. 

You can stop function -  Stop running when temprerature is over 80℃ - only thing  you need  restart miner with PSU manually.

Nothing wrong with 60C, I'm almost permanently at 55-60C due to a 35-40C ambient.

I have got a static outside IP as this is a business premises and I have set the S4 to have a static inside IP. I have port forwarded to 22 (SSH) and 80 (HTTP) of the S4 IP. I can assure you there were no network problems as I run my own servers for hosting, so I hope I know what I am doing there.

I'm just hoping someone who has played around with an S4 a lot or staff from BitmainTech would be able to shed some light on this matter because so far this has not been easy to manage remotely with the issues I have been having, for example with 1 board randomly over-heating when compared to the other 3 and hash rate changing after reboots.

After reading the posts about the voltage regulators not functioning like they should I am a little worried this might be a similar problem or the same thing. And with the stock power supply already close to max it's not good if it is.

First off, your IP Address provided to you by your IP needs to be a static IP instead of dynamic.  Mine was dynamic with charter communications.  I had to upgrade to a business line with them to get a static IP.  I'm paying $21.00 higher each month for it.  The plus side is if my internet goes down, they are supposed to have me up no more than 4 hours later.  They give business subscribers higher priority over residence.

Once you have a static IP, I would recommend you going to youtube to see what you need to do to connect to devices (your S4) through your router and/or switch that are connected to your modem.  I'm saying to go to youtube because of so many different OS's out there; versions of that OS; routers, etc...

I'm assuming you are set up for DHCP.  You would need to know what address was assigned to it or that you manually assigned to it in your settings so you can connect to it after you connect to your router via the static IP address.

The router would have to be set up a certain way, etc...  That's why I'm saying go to youtube after you get static (same IP address all the time) instead of dynamic service, which changes the IP address all the time.

For instance, this youtube video tells me what one would need to do in a similar situation you're in with an Apple Airport Extreme Base Station:  http://www.youtube.com/watch?v=gpeRdji4BmM

Yes, they talk about connecting to other "Mac's" within your house or business.  You can also connect to any other devices assigned addresses in DHCP in Airport Extreme Base Station.  However, you first need a "static" IP address to connect to the Base Station so you can connect to other devices through the Base Station.

As for what could be wrong with your S4, I have no clue.  Not my expertise.  Good Luck!

Wait until others wake up and head to the forum to read new posts.  Then you may find your answer.

I had a situation with my S4 2 days ago where I was changing pools and after I clicked save & apply it crashed.I could not access the web interface nor was it mining to any of the pools. It took me about 2 hours to get to where it is stored and it was running quite hot and roaring like it was trying to take off on a runway. I did a hard reboot and monitored it for an hour. Everything seemed to be running better than before since it was now hashing around 2.1TH instead of 1.9TH so I went back home. After about 3 hours running I noticed the temp rise on 1 board from 49C to 61C. I was not able to get to the miner to reboot it again so it ran all night like that with me stressing.

As soon as I could get to it I hard rebooted again and monitored it for about 4 hours this time. Every thing seems to be running normal again with the boards at 51C and hashing at 2TH now.

I would love to know what could cause this so I can try not to do it again... 

How can I remotely stop the antminer? I know I would only be able to stop it if I can connect to it, but when it is running hot and it seems like something is wrong I would like to be able to stop it so it does not damage itself.

I'll need to get my multi-meter out then and do what you did.

Thanks again.

thanks a lot.

answer is simple, if device havent got any problem default config is useful
but you can see my pics i replace all stock screws too, because all of stock screws is big for this pcb and these are not tight.
if you open this case you can remove with your bare hands. poor fabrication. not torked.

One more question:

In your opinion, is there any harm with leaving it at the default configuration as is?

That's what I thought...

I was just making sure.

Thanks again for your patience; time; and hard work.

No... that is not a solution. this is my best working parameters. not a solution........

And the way to solve it [for now] is to reduce to 187.5 Mhz at 0.685 Volt?  Just making sure you did not do something else as well?

Yes thats right.  i can measure stable results, only after i found a master problem and solve it

Curious:

Does this also mean board J7 will remain at 0.725 Volts while the others are at 0.685 Volts?  Cause I think you said J7 was un-configurable?

This would mean we can expect this one board to probably be considerably hotter than the other boards in miner status.

I was just about to ask you for the actual hash rate and wattage.

Thank you...

of course that is lower than 2Thash but also eat lower energy and also lower Temperature and lower noise
like 1800Ghash 1060W

i think that voltage adjust problem is master reason of psu's blowing because developers unexpected situation like that.
they put a 12V 120A top limit psu and they expect 1200w power usage but not, some of hash boards still working warning limits...
