Well........looks like I get to create my first repair ticket. This is absurd. I waited 2 months for these L3+ to come in and one of them has a bad hash board. At least that is what I'm guessing has happened. recap-I noticed an X where there should've been a 0 on the first ASIC. So I rebooted the miner, it came back online and this is what happened.
See pic below

**UPDATE*** The zero's are now XXXXX instead of 0000 on the first board.

I have also noticed that this miner is making a weird low howling noise..its different from the other L3+, i will probably try to figure out how to dis assemble it and see why it is making this noise.




Its like it isn't even recognizing the miner.


I tried
-rebooting multiple times
-upgrading the firmware to the firmware on their website
-seated all the power cables
-tried a different PSU

And I still get the same thing. When I researched on Bitmains website they said these are symptoms of "Chain scission of chips" or something like that. Anyone have any suggestions? If not then I am going to ship the board to them (I guess just the board and not the whole miner?). Has anyone had any luck sending to their US Facility that they list in California? I would like to send it to them and get it warrantied. Any advice would be appreciated..



That sounds like your board is gone....  Did you OC it?

If you did not OC it, open a support ticket and get the repaid done as fast as possible. The good thing is you can keep the miner with 3 boards and still earn money.

My controll board was broken and I was not able to do anything with the miner until i got a repair

I didn't touch anything on the software other than the mining pools lol. I guess I'll send them the hash board..are they hard to take out? Has anyone used the US repair facility? Or should I just ship it to their China facility?

It's easy to take the board out, just unscrew 4 screws the side where the exhaust fan is (will have to break warranty sticker for this) and pull it out. I used LA facility and they fixed it and shipped it back in 10 days.



Thank you for the reply, will breaking the warranty sticker void the warranty? In other words, should I just send the whole miner to the US facility or should I take it apart and send only the hash board? and if I send just the hash board, do I create a ticket for it first and make sure they are ok with me removing the hash board? I noticed on their website that you need their permission but I'm not sure how strict they are on it.

Should I call the US facility or email them or should I just open a repair ticket and send it to the US facility?

Sorry for all of the questions lol, I just want to make sure that I do it right since the whole process of RMA is confusing through Bitmain. It seems like you are supposed to box everything up first or at least get a tracking number and ONLY THEN can you start the repair ticket on their website, when you have a tracking number.

Mine was #6 which says take a board out. So I just created a ticket (it was auto approved), printed a form, took a board out and shipped it to their CA repair facility.

Ok, So I am going to go ahead and get an L3+ and PSU from Bitmain.  What is the easiest way to change my Bitcoin to Bitcoin Cash?  I got burned on another "sale" from some other site that disappeared and am a bit over-cautious on making this happen.

So, I got BTC in my Bitcoin wallet and can send them BCC.  I can't find out if they accept this as the order invoice states BCH only.  Just don't want to do something stupid and lose money.
When they say Bitcoin cash they mean it. Only send BCC. Bittrex is the exchange I use. It's a very good trading platform for swaps. BTC to BCH and a million others. Transfer BTC to Bittrex wallet and then convert to BCH. Send BCH directly from Bittrex wallet to Bitmain Payment address which they'll supply to you. Make sure you send the exact amount they request including the shipping in the total. Good luck. Dealing with Bitmain is ALWAYS an adventure! Don't panic!! LOL.

Oh yeah. BCC and BCH are the same thing. Bitcoin Cash. Different people use both symbols interchangeably. I know....it's pretty dumb.

So, in my Bitcoin wallet, it says i can send it in BCC.  I guess it coverts BTC balance to BCC. Trying not to freak, but losing that other money has me edgy.  I just want to start mining!

What wallet do you use? afaik there is no way to convert btc balance to others coin in the wallet, you have to exchange it even like shapeshift.io

Anyone know of a simple way to make this work with wireless? Or a workaround for this?.... a way to perhaps connect this from ethernet to a wireless router that connects to a wireless network that is connected to the internet?

For me, there is no way I can connect it to a wired ethernet due to my circumstance... is there an easier way to do this wireless? Any suggestions?  

TIA

I am using Bitcoin.com wallet.  When you go to start a "send" transaction, I can enter "send address" then click on "Legacy" and it changes from BTC to BCC.  This was also on a tutorial on Bitcoins website.  
If there is a easier way (or safer way) I am all for it.

I just created a repair order. It shows status "uncollected", does this mean I still ship the board back to them? Just curious, on that link you gave me, does that count as them giving us permission to open the miner up? Or did they give you express permission? I just don't want to void my warranty. Lol

You have to unplug each board one at a time and check your miner status to see which one goes offline to identify which is which.

Ok so weirdly enough, I turned it all back on to do some testing like you said and it was hashing just fine..I had messed with the cables for a 3rd time but I don't see how that fixed it. So I went to put it back to where I needed it to go physically and I noticed I needed to redo some cords so I shut it off again, and then I put it where it needed to go and turned it back on and sure enough the board was missing chips again.. just my luck.. so I pulled it out some to do the testing, started it up, disconnected the 1st board then rebooted and confirmed which board it was. Then for kicks and gigs I plugged the board back up and rebooted yet again and it came back on with all boards hashing just fine.

So it seems like that board is going in and out if you restart it. Should I get it to where it is working and just leave it on and mine the hell out of it? Or should I go ahead and get it replaced?
Because it seems like if I restart it, then that board will hash 1/4 of what it is supposed to be hashing, but if I unplug the data cable from that board then plug it back in it starts working after I reboot again.

Any solid pools in Europe where they have  Einsteinium (EMC2)? I have read bad things about supernova.

Can you let me know what bad things you heard about supernova?  I am currently mining other coins there, they seem ok.
Thanks

Well........looks like I get to create my first repair ticket. This is absurd. I waited 2 months for these L3+ to come in and one of them has a bad hash board. At least that is what I'm guessing has happened. recap-I noticed an X where there should've been a 0 on the first ASIC. So I rebooted the miner, it came back online and this is what happened.
See pic below

**UPDATE*** The zero's are now XXXXX instead of 0000 on the first board.

I have also noticed that this miner is making a weird low howling noise..its different from the other L3+, i will probably try to figure out how to dis assemble it and see why it is making this noise.




Its like it isn't even recognizing the miner.


I tried
-rebooting multiple times
-upgrading the firmware to the firmware on their website
-seated all the power cables
-tried a different PSU

And I still get the same thing. When I researched on Bitmains website they said these are symptoms of "Chain scission of chips" or something like that. Anyone have any suggestions? If not then I am going to ship the board to them (I guess just the board and not the whole miner?). Has anyone had any luck sending to their US Facility that they list in California? I would like to send it to them and get it warrantied. Any advice would be appreciated..



That sounds like your board is gone....  Did you OC it?

If you did not OC it, open a support ticket and get the repaid done as fast as possible. The good thing is you can keep the miner with 3 boards and still earn money.

My controll board was broken and I was not able to do anything with the miner until i got a repair

I didn't touch anything on the software other than the mining pools lol. I guess I'll send them the hash board..are they hard to take out? Has anyone used the US repair facility? Or should I just ship it to their China facility?

It's easy to take the board out, just unscrew 4 screws the side where the exhaust fan is (will have to break warranty sticker for this) and pull it out. I used LA facility and they fixed it and shipped it back in 10 days.



Thank you for the reply, will breaking the warranty sticker void the warranty? In other words, should I just send the whole miner to the US facility or should I take it apart and send only the hash board? and if I send just the hash board, do I create a ticket for it first and make sure they are ok with me removing the hash board? I noticed on their website that you need their permission but I'm not sure how strict they are on it.

Should I call the US facility or email them or should I just open a repair ticket and send it to the US facility?

Sorry for all of the questions lol, I just want to make sure that I do it right since the whole process of RMA is confusing through Bitmain. It seems like you are supposed to box everything up first or at least get a tracking number and ONLY THEN can you start the repair ticket on their website, when you have a tracking number.

Check here which is your case: https://bitmainhelp.zendesk.com/hc/en-us/articles/220872007-Possible-problems-for-Antminer-Troubleshooting-for-S7-S9

Mine was #6 which says take a board out. So I just created a ticket (it was auto approved), printed a form, took a board out and shipped it to their CA repair facility.


Ok I will open her up then and pull a board. How do I know which board it is? It says #1 but I don't know where that is in relation to on the miner.

Boards on your status page from the top to bottom corresponds to the boards on your miner from the left to right.

Ok so weirdly enough, I turned it all back on to do some testing like you said and it was hashing just fine..I had messed with the cables for a 3rd time but I don't see how that fixed it. So I went to put it back to where I needed it to go physically and I noticed I needed to redo some cords so I shut it off again, and then I put it where it needed to go and turned it back on and sure enough the board was missing chips again.. just my luck.. so I pulled it out some to do the testing, started it up, disconnected the 1st board then rebooted and confirmed which board it was. Then for kicks and gigs I plugged the board back up and rebooted yet again and it came back on with all boards hashing just fine.

So it seems like that board is going in and out if you restart it. Should I get it to where it is working and just leave it on and mine the hell out of it? Or should I go ahead and get it replaced?
Because it seems like if I restart it, then that board will hash 1/4 of what it is supposed to be hashing, but if I unplug the data cable from that board then plug it back in it starts working after I reboot again.

Mine were acting up like that too, they were running for a little while and then shutting off. Just unplug it and let the miner run with only 3 boards.

I let it run for a while and it started acting up again with a ton of HW errors. So after all of this, I'm going to just pull the board and send it to them. When you said earlier that you was "automatically approved" how did you know this? How will I know it? On my repair ticket it says "uncollected" but that could also mean that I haven't sent it to them yet. Again, sorry for all of the questions, I just want to make sure I'm doing this right lol

When you submit a repair ticket you will see a pop-up that it was successfully received and you will see the address where to ship it.

Uncollected means that they did not receive it yet. When they receive your miner it will switch to Collected.

When you ship it you need to come back to your repair ticket and add the tracking number to it.

How my L3+ was hacked!

Waking up today morning i found my L3+ was not hashing. It turns out it was hashing for some one else on nicehash with BTC address:
14c2ewCFeW1VYtyhLFWB6rFJV36ZysEWUf

https://www.nicehash.com/miner/14c2ewCFeW1VYtyhLFWB6rFJV36ZysEWUf

it seems some one out there has auto scanner searching network for L3+ and inputs default password of Root:

i only lost 8 hours of hashing on 1 machine.
here are the following mistakes i made:
1) I put the L3+ in DMZ (nicehash was not working so i figured DMZ might fix the issue)
2) I kept the default user and password
3) disabled firewall on my router

Just a headsup to people. to change the default password.

In all honesty it was my own stupidity and complacency.
