S9 help!!!!!

[BitCoinMiner123]

Hello all,
This is my first post to the forum, but I frequently use this as a source for information in troubleshooting.
So lets get to the details.I am having 2 issues that are very similar but different. I am going to be as descriptive as I possible can,so I apologize in advance about the novel.

Issue 1
Unit will start to boot up, I can access the units main/home interface page but as soon as I click on any of the tabs, miner status/ miner configuration/ network, the unit becomes not reachable, and when I go look at it, it is completely powered off, no front or top LED lights and the front and rear fans aren't spinning, yet the fan on the power supply is still spinning
I have replaced the power supply, test voltage output on all the sockets of the previous power supply and they all read 12/12.1 volts, which is right where they are supposed to be according to the label on said power supply.
I have changed its Ethernet cable, not that that would really help, but for the sake of troubleshooting, its better sometimes to replace everything that way you can eliminate possible trouble sources.
Haven't changed the units power cord yet as it was working properly when the unit was installed.- May try that just to be on the safe side.
I also haven't cracked open the unit yet as its still under warranty and I DO NOT want to void the warranty if at all possible.

Issue 2
It is similar to the above issue but different
So this unit will boot up and start hashing, after roughly 30 minutes the unit will be displaying zero in the RT hash rate, after a soft reboot unit is back up and hashing, it'll be this 3 or 4 times and then on about the 4th reboot it becomes not reachable, and same thing as above, unit is completely powered off expect for the fan on the power supply
According to the temp on the miner status, when unit is hashing of course, it doesn't appear to running hot.
Fans spinning at good speed somewhere between 1800 and 2200 RPM's.
Same troubleshooting steps taken as above.
 

Here is a snip it of one of the units main interface page

I can upload photos of anything else that may help in solving this problem.


If it makes any difference, these 2 units have been low hashing units since purchase, I have installed the latest Nov 29th firmware from Antminer and have had luck with that firmware fixing some other units that were also low hashing.
I haven't contacted Antminer yet as I hear they can be very slow or uneasy to work with in regards to tickets/warranty/exchange type situations
Do you guys think that it may be the controller board or IO board, that is causing the issue?
I have searched and searched and searched forums and google for similar issues to this and have yet to have luck.  
So any help that you can give would be GREATLY GREATLY appreciated

I can't see the screen cap, can you please upload new ones? and specify batch number, working freq, screen cap of the firmware screen, psu model, etc.

[BitCoinMiner123]

I changed the image type to jpeg that might make the picture more view able.

Also I have attacked snip-its of the units main status that shows the kernel version firmware version etc. I will hunt down the batch number and reply once I have the information

First screenshot is of the unit when its powered off, not sure how much help it'll be but hey more information the better

This screenshot is of the main minus status homepage

This screenshot shows the miner status page, which you'll see in the picture that fan6, which I'm assuming in the rear fan, is spinning rather fast but with the Nov 29th firmware version, and several prior to that, you no longer have control over units power setting or fan adjustment, temps seem within operating range, both fans are working properly, units power supply is outputting correct voltage and amperage to each hash board. Only thing that I can really thing of is that either A) the unit gets an error on one of the hash boards and cant correct the error so in order to protect itself it shuts down, or B) the unit get an error on the controller board(IO board) and cant correct the error and to protects itself it shuts down. Those are really just guessing games because I honestly no ZERO clues to what is actually causing this to happen

still can't see the pictures, use any other image hosting service besides google, I use  http://imgur.com/

[BitCoinMiner123]

Ok I just set up an account on there so hopefully the images will be view able now

This is the main homepage screen when the unit powers itself of, it may be worth mentioning that I can access the main homepage but any of the other tabs aren't reachable

This is the firmware version, it has been upgraded to the latest firmware released by antminer

This shows the status page, as you can see the temps are within operating range, the second, or atleast Im assuming is the second or rear fan, is spinning higher then I would like too see it run at, but with the newest firmware you no longer control over the speeds or power settings

Also thank you for being patient with me 

[ANTZ25]

I haven't had these problems with my miners, a lot others, but no this ones, I recommend you to open a ticket on bitmain's website and explain the situation, it seems, I'm not sure, the control board, you mentioned they are still under warranty, use it, because after that they charge between 200-300$ for repair any board plus shipping, before that you could try reflash the firmware, or maybe try the stock firmware they came with if you can find it. the fan speeds look unusual, they should be spinning at around the same rpms, when you open the ticket at bitmain's they give you the option to upload screencaps, explain the problem to them, I think is the control board not sure.

[BitCoinMiner123]

I am beginning to think that I will have to open a ticket, I was trying to save that as a last ditch effort so to speak.
I will try messing around with the firmware but am cautious of that because I've had a few units "brick" after doing firmware upgrades.
Thank you very much for the help!!

this should help   and that means you did not shrink your images with auto feature to 1600 by 1200 or less on imgur


I redid the bottom one.  The fans are weird 2600 and 4900 are too far apart.  the rest is good.   what is your psu running this miner?

It could be good and the psu may just be shit so it powers down after 2-3 hours

[BitCoinMiner123]

I was also thinking that those ranges of fan speeds were to far apart also.
As for the PSU that I'm using I've tried 2 different types
Have tried the APW3+-12-1600-A3 which is the newer style I believe and have also tried the older APW3-12-1600-B2, both have yielded the same results. If it helps I have changed out the power supplies on the 2 units that are having trouble and put those power supplies on other units and the problem has not followed power supplies, I have also tested each socket on the power supply and consistently get 12/12.1 volts on each connector of each socket, I will be opening up a ticket with bitmain to see if they can help with the issue. I am beginning to think that it is a problem with the units IO board, but I am by no means an expert on these devices.
