Antminer S7 B10 Failure

[dannygroove]

Hashes for about 15 minutes and after that, the green light stops blinking. I changed PSUs just to be sure and the issue persists. There is no connection to the setup page, I did notice that the 3 hashing boards are hashing perfectly. Is this a controller board issue? Anyone had a similar problem?

Thanks

Edit: Im using APW3-12-1600-B2 PSUs

Have you tried to reset the board with the reset button next to the Ethernet port?

im pretty much new in this community  , started mining a few months ago .. i had a same problem with one of miner i ordered from ebay . Its worked fine for the first few hours, i was able to set up the pool information...etc,  then i was not able to log in to the web interface. Hashing boards worked at full speed, confirmed this from the pool website . I reset the board with the reset button next to the Ethernet port , this step is fixed my problem ... You should do this  , after you confirmed your power supply is ok . Make sure if you are using DHCP , for any reason the Miner IP has not been changed ... next step ... maybe replacing the controller board.

Ello,

One of my miner had an issue with hashing and access, it'll hash perfectly above 4.5-4.7 ths, after 15 hours, it'll go to 2.5-3.5ths, not sure why, there are no - or x on the status.

But i managed to solve it by having a timer plug, where every 12 hours it'll restart my miner, and has been perfect ever since.

EDIT: and i did a factory reset prior to solving the issue

Sorry for not getting back to you before. I will try resetting the board as soon as Im in the depot (Tomorrow). I hope that this helps as I now have 2 machines with same condition

Before you using the factory reset option ... make sure the ip address is not changed for your miners .. if you have 2 miners with the same problem and using DHCP , maybe the ip's for those miners changed for any reason ( ip lease time expired , your old ip assigned to another device on the network and your miners got a new ip ...ect),  Different IP can be a reason why you can not access to the web interface remotely or locally  . Connect you computer to the same network , log in to your router and check the IPs ... If you dont have access to the router , use any network scanning program , it will show you the connected device's with name and IP ...

This problem will affect everyone including you as long as 114.114.114.114 is down

IPs are fine, they haven't moved since I set them up. Thank you

Interesting, Ill try that soon and report back!

Problem is, I cant even connect with Putty as the miner appears to be completely inaccesible.

Sorry for my mistake, It must not be the problem I linked, in fact it seems it has been fixed in new firmware and your B10 might already be fixed then.

Hmmm... I've been adviced not to do firmware upgrades. Now im at the crossroads.

I have always updated to latest firmware for 20 or so of my S7s without any issues, and they are all hashing like new. I did it through VPN connections since they are at 2 different data centers.

One bad flash or electrical loss and you will be very mad at yourself for doing a bitmain firmware.   Read the stories there are many horror stories, and you normally don't gain much.

Mine was a S3 that failed, ever since I don't upgrade bitmain gear unless 100 percent necessary.  Just a lot of bad possibilities for very little good.

If you have problem accessing the web control panel, at this point, you some options before upgrading the firmware.

First, please try a different web browser.  Some times some browser has Cache problem and specially windows 10 built in browser, you may experience this access problem.

If it is not the browser related problem, please try to reset the S7 with a reset switch located to the "RIGHT" side of the ethernet port.  It is a little pin-hole.  Please use a paperclip or cellphone Sim extractor pin and press and hold the button inside for about 10 seconds and then let it go and wait for about 30 seconds and repeat the process.  Then power it off and power it back on.  When you reset the S7, it will bring to the factory default setting.  

If these does not work, then if you can access to the Firmware Upgrade page, please update to the newest firmware from http://www.bitmaintech.com

If none of those work, you may want to request the warranty process or local repair options if you are in Ukraine, Venezuela or USA.  You can email support@bitmainwarranty.com to request assistance.

Regarding the firmware update, yes, if you do not need the update, please keep it as is.  (If you have older firmware prior to December of 2015, you may want to upgrade the firmware as newer firmware has improved cooling setting for the built in fans)
