I just received another S1 today and this one was used big time. Lots of Chinese dust all over the PCB boards and fan blades. Should I contact them and have them replace it?

Also might be a sign of things running out and new model coming out.

You are lucky that your S1 works.

I received heavily used and semi-dead S1 from them.

All covered in dust, heavy smell of burnt electronics, a lot of dead chips - one blade shows 8 ASICs instead of 32.
It hashes only at around 120 GH/s and sometimes just stops hashing with beeping sound, needs power cycle to start again.

I paid 130 euros customs tax for this unit, and it would cost around 200 euros to ship it back to Bitmain and then I have to pay another 130 euros to customs for the replacement unit.
Just does not worth it.

So Bitmain sold me a dead unit and now just stopped responding to my messages.

1) screenshot?
2) what is your PSU - dead chips and rebooting are common signs that your PSU is a bit too weak (you need one rated 550W+ with at least 500W on the 12V rail to run properly)

1) here is the photo of my monitor screen
2) I run it with Corsair RM850. It's a pretty good PSU, I have another two of them powering two Ants S1 each without problems.

Actually I don't care much just was sort of disappointed when paid heavy customs tax for this unit only to find that it's all dusty and semi-burnt.

you don't pay nothing to send it back, they will pay, and they will ship you a new one, if what you told is true, u make a photo and a screenshot.
else i don't belive you at all.
they have 10000 of customers, and no one point that(one blade shows 8 ASICs instead of 32), you are the first one.
or, you didn't buy from https://www.bitmaintech.com , and you got scamed.

Bitmain told me that I have to ship it back by myself.
I've sent them a photo / screenshot.

else i don't belive you at all.
I don't care if you believe me or not.

I'm not the first one, if you read Antiminer topics at this forum you will find people with similar problem - dead chips.

or, you didn't buy from https://www.bitmaintech.com , and you got scamed.
I bought 5 units directly from them. 3 were new and good, one was used but good and another one used and defective.

yeah mate, sry, but i really think this is how it will look.
obviously its a prototype, for a few reasons:
1) a paintjob would be cheap, protective, and look good (but KNC skipped this, so maybe not)
2) it has no connectors for a rack frame yet
3) there is a fan on top? If these are stacked in a rack, that fan would be absolutely useless unless the box also has a hole in the bottom for some crazy vertical airflow concept

What about the 1000W with 1000W PSU.  An option to ship without PSU?. 

The 1000W power number could come from anywhere.
1) 1000W at the wall means a draw of 880-920W
2) 1000W unit would need about 1100-1200W PSU for some overhead
3) 1000W PSU could run 900W of miners easily

No pictures yet of the production unit... just broken img on the site. Sad

The prototype bare metal box that bobsag3 posted on the other thread doesn't count... I doubt that represents how the S2 will look in the shipped production units.

Then again... the S1 wasn't exactly a looker either...

Read my post again... bobsag3 posted that picture of the PROTOTYPE.

We wanna see pics of the actual production units... jeez, I even specifically mentioned this photo in my post.  Roll Eyes

It could be ugly as hell, but it won't look like that... not if they are serious about saying it's a 4U rackmount case.  The prototype looks much bigger than 4U.

They say it's a 4U case. Other than that, I couldn't care less how it looks. It's not going to be sitting on my coffee table. It's going to be buried in closet/hosting facility.

Newb here.  I have one S1, and thinking about getting a second. 

I am using one CX500 PSU.  should i just get another CX500 for the second unit, or go for a single higher wattage PSU and use it for both?

ARGH!  Cry

Does anyone know what hours Bitmaintech keeps? I accidentally sent too many bitcoins to them... and I need them back for a different order from them. Sad

Hi, I just order one at Wednesday evenning my time. Today I received my shipment information with estimated delivery on next Tuesday  Cheesy.
I can confirm fast shipment and looking forward to confirm that my Antminer is working well.

As I am preparing and reading here and around and in web installations tips. Shell I check for thermal grease as someone reffer to have a lot on the circuits? Any tip to follow before first power-on?

I have purchased good PSU - EVGA SuperNOVA NEX650G
I have my LAN using 255.255.0.0 subnet - I am a little bit confused when I see in management system of Antminer sections/menu LAN and WAN - any reason for that? My WAN is a at Gateway and I do not care about any setting.

Thank you for any tip.
 

The control board on the S1 is a customized router running OpenWRT so you use the WAN settings on the board to connect to your LAN.  Don't get stuck on the terminology Wink

The LAN settings are essentially going to point to nothing (no hardware port) and the WiFi settings essentially bridge to the S1's WAN connection.

So basically modify the S1's WAN settings (ignoring that it's called WAN) as if you were setting up any other hardware on your network.

My guess is that the power regulator (TPS53355) or its associated power components for the second 'segment' of the bad board died - this would result in no 1.1V signal to the chips or across the inductor, and would likely stop the communication chain to the 3rd/4th segments.

I had that happy to the first segment on one of my boards, and no chips on the entire board hashed. Bitmain took a few days to decide on what to do, and then mailed me a replacement PCB alongside my order for another antminer. I swapped the boards (the thermal paste application needed some work at the time, but seems fixed now since antminers all come with it oozing out) and mailed back my bad PCB at thier expense.
