rate density. 10 hashing boards are mounted onto a perpendicular motherboard in a 4U case along with a BeagleBone controller card. S2s are shipped in
custom expanded foam moulds and a bubble wrap jacket. A power cable, 19" rack mounting rails + screws and rubber feet are included.
| Chips | 640x Bitmain BM1380 Gen1 |
| Hashrate | ~1000GH stock |
| Rated Voltage | 12V |
| Power.Consumption | 1050-1150W |
0b) What You Need (top)You will need the following:
Click your flag to find everything you need to get started at Amazon! 
1) Powering (top)AntMiner S2s come with an internal
Enermax EPM1000EWT ATX power supply, costing
$250 on the open market. 6x 6pin PCI-E cables plug into the
motherboard which feeds the hashing boards via PCI style slots. We also need to tell the PSU to always be on, as there isn't a motherboard to do this.
Cut a paper clip into a U and insert it into the green wire and either black wire to the side of the green wire. Tape it up for safety. The power supply
will now be controlled by its switch on the rear socket.
- Plug the PSU into the mains.
- Power is controlled by the rocker switch on the PSU.
2) Cooling (top)Cooling is performed by 4x140mm 25mm thick JDH14025B fans manufactured by Jiang Shan Lai Electronics. Two fans exhaust in conjunction with
three intaking fresh air. They are PWM controlled by the firmware and plug in via 4 pin headers to the motherboard. Noise levels are very reasonable when
ambient temperatures are kept <25C. The fans slowly step up to deal with the hottest module temperature. Each mining board has a full cover aluminium
finned heatsink.
3) Case (top)The case of the AntMiner S2 is designed be rack-mountable in a 19" wide rack (482.6mm) and occupy 4U of slots (176mm). They are stackable and can
operate on their sides without problems. The S2 includes an LCD screen which displays the IP address, hash rate and max chip temperature.
Shipped weight of an S2 is 18kg, dimensions of the shipping box are 530 x 530 x 300mm. External dimensions of the case are 442* x 432 x 177mm
(+100mm for cabling).
4) Configuration (top)Configuration is straight forward as the AntMiner S2 is standalone and does not require an external controller.
- Power on as above.
- Plug in a network cable from the S2 to your router.
- Change your router's subnet to 1, ie 192.168.1.x. This is just temporary. If this is not possible, see below indented steps.
- Unplug your computer from all internet sources.
- Plug in a network cable from the S2 to your computer.
- Navigate to Control Panel -> Network and Sharing Centre -> Change Adapter Settings
- Right click on your ethernet adapter -> Properties
- Click on "Internet Protocol Version 4" and click properties
- Select "Use the following IP address" and enter the following:
- IP Address: 192.168.1.1, Subnet Mask: 255.255.255.0, Default Gateway: 192.168.1.99
- Resume normal steps.
- Using a browser, navigate to 192.168.1.99 - this goes to the S2's configuration page.
- If you have multiple S2s, you'll have to connect them one by one and change the IP as you go. If you don't you'll have conflicting IPs.
- Login using 'root' as both the user and password.
- (Optional) Navigate to Network -> Settings. Change protocol to DHCP client. Save and apply. This step will allow the S2 to accept an assigned IP
address as controlled by your router. - Navigate to Miner Configuration and enter 3 pool information. Save and apply.
- You can then change your router subnet back to 192.168.1.x or whatever you are used to using.
- (if optional DHCP step was done...) Navigate to your router and look up list of clients. Find the IP the AntMiner has now been assigned and navigate
to that. - Login if prompted and navigate to status -> Miner Status and watch check the unit is hashing.

| Problem | Solution |
| "x" in a row on miner configuration page | - There are just a few faulty chips - nothing we can do. Hash rate will be barely affected. |
| Almost all "x" on one row of "Chips" | - A mini hashing board inside is faulty or lose. Open up the case and take a look. |
| Almost all "x" on all rows of "Chips" | - Check that the power supply is properly plugged into the motherboard, and that all the
cards are seated properly. If no luck, try with a second power supply. |
| How do I change the login password? | - Navigate to System -> Administration. Enter the current password and enter your new one
twice. |
| What is the SSH login? | - Username "root", password "admin".
|
| My hashing boards came loose during shipping! | - This is a known problem and one Bitmain are working to resolve. Open the case up and
carefully remove all the hashing boards. Inspect for damage on the boards and the slots in the
motherboard. If everything looks okay, straighten up the slots, plug the hashing boards back in
and fire up. If only one board appears damaged, remove that and contact your seller. |
| Can I turn the beeping off when the miner stops mining? | - Navigate to Miner configuration and untick the box "Beeper Ringing". |
| I can connect to the Antminer but its not hashing? | - Navigate to Network -> Settings and make sure "Gateway" is set to the IP of your router. |
| What temperatures should I aim for? | - Try and achieve <50 for best hash rates, and <60 for long lifetimes. Temperatures should not
be let to rise above 65C unless doing testing. |
| Where can I get the latest firmware? | - Download from Bitmain's site. |
| How can I tell what firmware version I have now? | - Navigate to System -> Overview and look at "File System Version". |
| How do I install the latest firmware? | - Download firmware as above. Navigate to System -> Upgrade and click "browse". Select the
downloaded file and click "Flash image". Do NOT interrupt this process or you will brick the unit. |
| How do I reset settings to default? | - Use a paper clip to press the reset button - located next to the ethernet connector - down
for 5-10 seconds. The miner will then reset with stock settings. |
