eastshore tutorial for antminer s7

 

Antminer S7 is the best bitcoin miners in the bitcoin mininig market now. It’s 28nm bitcoin miner, however, the performance of Antminer S7 is much better than other 14nm bitcoin miners. In this tutorial, we will introduce the setting-up for Antminer S7(4.37TH @ 1293w) bitcoin miner.

 

{Update Log}

  • Update 04-01-2016: All the Antminer S7 miner sold now is the new generation of S7 miner. This new generation of S7 miner is with a new  and better design of  heat dissipation based on ONLY ONE FAN (NOT two). The noise of the new generation miner is lower too. Below is a picture for the new generation S7 miner. The setting-up for the new generation S7 miner is the same as  previous miner. In our tutorials, we will use the pictures from the previous  generation of miners.

{Visual Inspection}

  • When you first receive this miner, it is VERY IMPORTANT that you perform a visual inspection before powering the device. Give the machine a gentle shake and double-check that no heat sinks have become loose or fallen off in transit. (If the device is powered without heat sinks properly attached, the hash board will get burnt and will no longer function.)
  • If any heat sinks have fallen off, please buy a heat sink plaster in your local market to fix the heat sink. (The heat sink plaster is usually very easy to get in your local market and it is very cheap too.) DO NOT power on the miner before you fix the fallen heat sink. The following picture is an example of the heat sink plaster (The heat sink plaster should be sticky):

{Before Start}

  • Please prepare PSUs (can afford the power >= 1500w and with 6pin x 10); You can use several PSUs to connect to one miner. But plz DON’T connect 1 PSU to more than 1 miner or more than one hashing board.
  • Connect the miner to the router by internet cord.
  • For miner configuration, plz use the ethernet cord to connect the miner to the same router which your PC also connected. (Your PC is just needed for miner configuration) 

 

{Check Your Network}

First of all, you need to check the network where you will run your miner.

  1. Make sure your network is stable enough: The S7 miner has a high demand for the network. If the network is not stable, the miner may stop work without any warnings. In the most serious case, the hash boards of the miner may get damaged because of the unstable network.
  2. Make sure your router is good quality and stable.
    • You should NOT use a mini router(or repeater, or wifi AP, the 1st picture is one of the mini routers) for the miner. In our test, the miner will never start mining when connected to the mini router.
    • We recommend you to connect the miner to a really good quality router, like the 2nd picture showing.

{Miner Connection & Mining Guide}

  • First, please check if all the cables on the miner are inserted tightly.

IMG_9843

  • There are 10 x 6pin ports on the miner. You need to connect all the 6pin ports to your PSU.

IMG_9860

  • And connect the 6pin port beside the controller.

IMG_9861_mod

  • Important: there are 3 hashing boards in the miner, and 3 x 6pin ports on each hashing board. DON’T connect more than one PSU to one hashing board. (That’s means, the 6pin cords you connected to one hashing board should come from only one PSU.). See below pictures for the correct connection and the incorrect connection.
  • Correct Connection:

psu_connect_crt

  • Incorrect Connection:

psu_connect_ict

  • Power on the miner. (Important: If you used several PSUs for the miner, you should power on the PSU which connected to the 6pin port beside the controller FINALLY. For example, if you used a CORSAIR 850w PSU connected to the port beside the controller (And also the other two ports on the miner), so at first, we power on all the other PSUs, then power on this one). 
  • Wait for about 1~2 minutes,  the fan of the miner will work loudly for a while, then it will be slow down.
  • Then, please use software to scan out the IP of the miner on your PC. For how to scan out the IP of the miner, check here: https://www.eastshore.xyz/how-to-scan-out-the-configuration-ip-address-of-the-miner/
  • Then you can login the miner configuration page with the IP you just scanned out. (The username and the password are all “root“)
  • Change to the page “Miner Status” and keep refreshing the page until some data (Speed, miner account, pool etc.) is shown on the page (This means, the mining is starting. Generally, the miner need about 3~7 minutes to start mining). The fan of the miner maybe gets loudly and slowly for several times while you are waiting. And sometimes, the data on the page maybe disappear again just few seconds or one minute after the mining starts, don’t worry, please waiting for the miner working constantly.
  • Change to the page “Miner Configuration“, configure your mining pool address, mining account, miner password etc. And click “Save & Apply”. 
  • Save the changes, then wait for about 1 minutes for the setting applying.
  • Change to the page “Miner Status” again, and please refreshing the page until there are some data shown on the page. Then the mining is starting.

  • If there is no any data shown for a very long time (for example 10 minutes) or there are a “BiBi” noise comes from the miner, please try to restart the miner (power off it, wait a minute, then power on it again). After restarted, please change to the page “Miner Status” page and waiting for data showing.
  • Different miner may act differently from each other,  just wait for the miner working loudly and constantly. Here is a test video for this (When the PSU is just power on, the miner is not working yet, the loudly sound is from the PSU): https://youtu.be/C3mbu25eo9g

{Mining Tip}

Please pay more attention to the following tips if you are running several miners(<= 10 miners) together:

  • The red LED in front end of the miner keeps flashing

The red LED keeps flashing because of many reasons, such as the unstable network, the high temperature and so on.

Anyway, if your miner works very well with the normal speed, please just ignore the flashing LED.

However, if the mining speed of your miner is very low or there are some more serious problems with the miner at the same time(for example. the ASIC Status is shown as —–), please check the {Trouble Shoot} section below for more help.

  •  The heat dissipation
    • Please make sure all the hot wind which comes out of the fan(of the miner) will be exhausted timely.
    • And what’s more, all the hot wind would be exhausted in the same direction, and there is no hot wind will be blown into other miners’ air inlet end.
  • If you connected several miners into one power strip which is connected to the socket on the wall, you need to:
    • Please check the maximum current rating of your power strip.
    • For example, in China, for some of the power strips, the maximum current rating is about 2000w. As the power consumption of the miner is nearly 1400w, so it is better to connect ONLY ONE miner into one power strip. Or the miner might stop working. 

 

{Mining Speed Note}

  • The final model of Antminer S7 is “4.73 TH/s @ 1293w” with the “Default Frequency” set as “700M”.  (The submodel of the new generation miner is “S7_F1”)

submodel label of antminer s7

  • The rated speed of Antminer S7 is “4.73 TH/s ± 5%”, so the speed may fluctuate between “4.49 TH/s ~ 4.96 TH/s”.
  • In our test, the “GH/S(5s)” on the “Miner Status” page may change frequently, but the “GH/S(avg)” will keep stable. So please don’t worry about the frequently-changed speed of “GH/S(5s)”.
  • However, if both the “GH/S(5s)” and  “GH/S(5s)” are very low (eg. 3000GH/s), please just restart the miner, and the speed will be normal.

 

{Trouble Shoot}

For all the troubles you get in the mining, please try the following suggestions:

  • First, please try to power off  the miner then power on it again. 
  • Check your home network, the mining pool to make sure all the network are working well.
  • Check if all the cables on the miner inserted tightly. Especially the three cables connected to the hash board. They may get loose in the shipping.
  • Did you connect all the ten 6pin ports on the miner to your PSU? All the ten 6pin ports are needed for mining.
  • Have any heat sinks fallen off? Give the machine a gentle shake and double-check that no heat sinks have become loose or fallen off in transit.
  • Try to reset the miner. There is a reset hole beside the internet port (the hole in the red circle in the following picture). After the miner powered on and running, waiting for 5 minutes(until the miner start mining), please get a sharp pin and press the hole for about 10 seconds. Then please wait for about 5 minutes for the resetting. You may need to rescan the IP address of the miner after reset.
