Plug it directly to your computer/laptop and change your Ethernet adapter settings. Go to the Ipv4 and change it to the following:

IP Address: 192.168.0.254
Subnet: 255.255.255.0
Default Gateway: 192.168.0.1

DNS: 8.8.8.8

Then unplug and re-plug in your miner. Now try the IP address from the side of the machine. If that does not work then try using an IP scanner program such as angry ip scanner (free version works just fine) http://angryip.org/w/Download. Now search from 192.168.0.1 to 192.168.0.254 If your Ethernet adapter is setup correctly, it should tell you which ip address to use.

You could also just try 192.168.0.100 as a default for some machines.

Doe everyone have different IP address on the for the miners. I am hard wired to a router and the IP addres I am using is not gettin g a signal.

You sent me the wrong tracking number because on the DHL site it says: Service Area destination:   SACRAMENTO - MATHER, CA - AUBURN – USA

I contacted DHL and  this is the tracking number for a package going to the usa

And I am located in the Netherlands.
Could you please send me the correct tracking number?

Thank you.

Please let me know when you will be able to deliver repaired miner to DHL and give me the tracking number?

I would like to know if you managed to ship today or if you will be shipping tomorrow?

Thank you!!

I have still not received a tracking number? Will you send me the number or will DHL?
 
I ordered on January 8 and paid with bitcoin.
 
Thank you
 

Because the chip group on the left are working, but the group on the right are not, I would strongly suspect the SMD soldering on one or more of the chips in the non-working block (if it were a capacitor or other component, it looks to me like that would have taken out both columns of chips that seem to share the components on top of the board).  It is very common with SMD processes and poor QA that there is a bad solder joint or two but you **cannot** see this with your eyes.  Only testing (e.g., QA testing) can detect this.

What I would do is try to reflow the solder.  If you don't have access to a high end reflow machine (I assume you don't) you can do it for $30 by getting a hot plate from Target.  Sparkfun is a great reserouce especially for this kind of thing: https://www.sparkfun.com/tutorials/59.  Go to the hot plate reflow method.  Let us know if that works and be careful not to melt your board; go slow and be patient.  I have fixed several boards this way.  I have one of these trash-hashers coming (soon? who knows...) and I am keenly interested in whether this works since it appears to be a common problem.

If it works, feel free to send whatever bounty you think is worth it! 

I'm willing to pay bounty to oneone helping me to fix why these 5 units are not hashing, left ones are. Chips inside the red area are all cold. I cant see anything wrong in the board but i'm no SMT expert. I can solder tho.

Is that for both?

The miner is running, but I got some problems.

2. Hashing speed is low.
The hashing speed is around 172Gh/s instead of 200+ How can I fix this?

still selling two bt miners - in hand - pm me - 2.4 btc

Check the PWM cable. Color should be Black/Red/Yellow/Blue.

I love this race. Every week is a new price.
Kncminer is gonna shit their pants when Avalon/Bitmain hits $3/GHs

Its the same menu where you input pool info.
Just type in  --avalon-fan 20-50, under "More Options".

How can I acces the CGminer on the miner?

--avalon-fan in CGMiner settings under more options. I believe the setting is in reverse though, put it at 90 and it is quiet, 20 and it is full speed.

edit: by quiet I of course mean quieter, these are nothing like the original ones for sale at the start of this thread (with video evidence in the thread showing them being quiet). The fans are 36w and even at the lowest setting are too loud to be in the same room with, it's like server equipment.

Look at the bottom. IP should be written on the bottom of the case.

howto find out the IP for the BTminer/ how do i log into the interface

I have two units one is reverse otherone is not.

Unit1 with working RPM in webui  "--avalon-fan 20" seems to put the fans around 20% very quiet
Unit2 with unworking RPM in webui "--avalon-fan 80" seems to put the fans around 20% very quiet. Value 20 is very loud 80%
