Topic: Bitmain's Released Antminer S9, World's First 16nm Miner Ready to Order - page 163. (Read 531173 times)

I'm glad you got may have it solved.  I did a couple accidental hard restarts and now it's hashing upwards 13.7 from 13.6.  Hopefully you'll have the same luck!  

Do you have a Kill-A-Watt or something to monitor the PSU? I assume it's getting 1600W ... when mine was idling it was only pulling 0.5A, then 1,2 and a spike to 12A and 1400W (on 110v) as it started hashing.

  Ha! This is an interesting one  - This is what solved the mystery:
https://enforum.bitmain.com/bbs/topics/3957

And here the chain of events:
1. Tried sliding out the controller board to look at components, but realized that it was not made to be slid out - so slid it back.
2. By doing so the "IP Report" button was inadvertently depressed and kept there.
3. When the board booted - it followed its reset routine over and over.
4. I noticed the rebooting over and over with the red "fault" LED on.
5. After resetting the router I noticed the stuck "IP report" button, which was then fixed.
6. The board failed to come back none the less.... until I realized what had happened and the solution as above.
7. A proper hard reset using the "IP report" button brought the board back to life.

The miner must have been stopped in an unlucky state and was unable to initially complete the reset procedure.

Now is it sitting there, waiting to start up the miner daemon, which supposedly takes a while sometimes. 17min and counting...

--edit---
Still nothing. The "single-board-test" program seems to hang. It ends up listening on port 6060, and does nothing after that. The /sbin/monitorcg script does not start the miner either. A manual start of bmminer detects the 2 connected hashing boards, but then reboots the OS? Confused.

I am weary of "upgrading" the firmware, since the latest firmware in the BM download section is from November 2016, while my system seems newer: File System Version Tue Jan 24 22:42:36 EST 2017. Is there any newer firmware available anywhere?

Is it safe to flash the eg. s9-20160715-550M.tar.gz firmware from BM on the latest 13.5TH (shipping on 20/Feb) miners in order to under clock the miner?

Thanks for the reply. It was idling for a while - maybe 30mins. Before this happened, the IP connectivity was available pretty quickly. The green LED (front) was on and it took a few minutes to initialize the hashing boards. Now there is no IP connectivity (ssh, ping or http), no green LED and obviously no hashing.

Going to try the "s9_fix_upgrade" via SD card - fingers crossed.

1. reboot your router
2. did you wait for at least 30-45 min after you rebooted the miner before going all in?
This is how long it takes to start working-this is normal. It just sits there.
Before it was 15-20 min, and before 6-7 min (all times with different S9)
3. I am not sure that doing this with disconnected boards makes sense because controller actively interacts with the boards before starting them.

Thanks for the help on pools - Kano seems like a nice pool...

BUT managed to trash the control board somehow - it is not booting properly. Ethernet link LEDs come on, but neither the green nor red LED light up. The fans stay at their low idle speed. Disconnected all the hashing boards, and just trying to boot up the control board. The static IP is unreachable and the DHCP server is not seeing a DHCP request either.

Trying to recover the FW via SD, still figuring this out... or better by TFTP? The SD instructions seem old - they reference the S7 firmware, while the S9 firmware has a different file layout.

Has anyone managed to connect to the /dev/ttyPS0 console via the pin headers? Is this TTL 5V RS232 or "real" RS232? The speed seems 115200bps as per a previous dmesg dump in the thread.

If anyone has any hints, they would be appreciated.

Not going to retyped it all again so ref https://bitcointalksearch.org/topic/m.17968291
Done that way each cable is protected plus easier to wire and fuses cost less.

I had only Antminer S1 and Antminer S2 pointed to solo.ckpool during that time, so it was extremely lucky.

What was your setup when you got this - #391994 at solo.ckpool.org ? Nice!

Kano or Slush for example..

What are the recommendations on pools for a single S9 miner at present? Eligius seems to be de-funked - it was a nice free anonymous pool with useful stats...

Bitmain's pool? They seem to have a charge. P2pool is not an option at the moment.

Thanks for any info.

Anyone noticed that bitmaintech's site is now unsecured. Their SSL cert expired? Any word from bitmain itself? Are they even aware of this?

--edit-- nevermind, it seems bitmain is not using the bitmaintech.com domain anymore that's why.

thats about the norm for the s9 autotuners....they are all very noisy.

Can somebody confirm whether it is "normal" that the fans run at about 4200rpm with an ambient of round 25C. Hash boards are at 77C and 83C hashing away at 4690 and 4680 Gh/s. There is a high pitched whistling sound.

Thank you for this input. Im eyeing on the 1600w now.

The EVGA 1600s are rated for continuous loads so that's plenty.  I've read the reviews and the PSU can actually handle temporary peak loads up to 1700 watts (though it's terrible for the PSU).  Proper functioning S9 shouldn't draw more than 1400 watts at the wall.

I contacted their support, asked them why it happened, They said it was my PSU giving irregular voltage. They then asked me what PSU im using, I informed them its their Bitmain APW3+-12-1600W PSU. I'm waiting for a reply now.

Yes sir.. My power supply is still working with 12v.. that's odd. With your years experience in electronics. what can you suggest? Do I just put a 80a fuse between the power supply and miner? How do I put it? one fuse for the positive, and one fuse for the negative?  I have 3 more S9's coming nxtweek. I can surely have a super advice from you sir. Thanks.

Thanks for this idea also.

They are $150-ish.  The EVGAs are $300 - $400.  I go higher end on those.  

Man, that really stinks.  I wonder what caused the problem.  Try calling the Colorado office for Bitmain warrenty at +1.844.248.6246???

Will buy the 1600 instead? it will be enough i think?
