Mine reboots and each time yellow light blinks. It's not able to power all 4 boards at once. When I connect 2 or 3 at a time I'm golden. Are they still using the APlusPower psu?

Hi All
Have been running my S4 (Batch 2) at 2T/H happily since March.
Just yesterday it shut down and will not restart - just get the flashing red light at the back indicating a fault and amber light on.
Was not aware of it operating above 60deg.
Any suggestions where to start when I open it up as I assume I will have to do.
thanks
I'm guessing you have already done it but I would try to do a restart of PSU. Using the button not the interface. Do you get anything to boot up on it or just psu indicating fault? If you are able to test the boards here is a guide - https://bitmain.zendesk.com/hc/en-us/articles/203361315-Board-Diagnostics But it is sounding like chances are the PSU is having problems and likely needs replaced. If all seems well on that and still getting PSU indicating fault I would make a ticket with Bitmain Support. I'm guessing it's out of warranty so you could ask how much for PSU.

Not sure if this has been discussed, I checked through many pages and did not see an answer, same here: https://forum.bitmain.com/bbs/topics/1753If there is a power failure to the S4, is there a way to have it automatically turn back on when power is supplied again, without having to hold down the button on the back? You could do like M's antmonitor and say if it goes under so much hash tell it to restart. But soft reset does not always fix hard reset problems. Also you have to leave a computer open to moniter it with this program. It's worth taking a shot of looking at though. With a power failure, M's antmonitor will not help as the machine will not turn back on unless you hold the button on the back of the PSU for 3-5 seconds. The SP20 and S5 do not have this issue, it is unique to the S4 PSU. If anyone else is looking for this, the answer is no. There hasn't been one report of a workable solution. Its part of the reason that the new PSU both auto-ons and has remote restart functionality.

Well I finally joined the dead S4 Fan(s) club. Had only 1 out the 4 reliably working so the 80c cut out got a good testing and passed with flying colors. While waiting for Delta replacements to come in I did a little experimenting and found that the fans from my retired S1's WORK PERFECT! Back to running just over stock speed, hottest blade is 69-70C which is just fine. (room is 90F). Happy happy joy joy! The only caveat is that ya have to use 4-pin fan extension cables but already have them on hand. Also dug up the post on parts/how-to repair the fans. https://bitcointalk.org/index.php?topic=796839.msg10827831#msg10827831

I wonder if Bitmain changed vendors for their fans in the last s4 production runs? I got my 1st 2 s4's shortly after B2 came out and so far fans in those are running perfect. The s4 with short-lived fans I got a few months ago from Zoomhash - it was the last brand-new in box one they had We are talking around only 2.5k hours run time vs at least 3x that on my other s4's. Hmm.

I just PSU indicating a fault - no indication of an issue - just stopped. Sounds like PSU replacement

Might check and make sure it's not something other like a flipped breaker. But if there is no flipped breaker and it's getting power still indicating fault it is a decent chance it will need a replacement. I'm guessing it's out of warranty but you can contact Bitmain support seeing about cost and getting another PSU here - https://bitmain.zendesk.com/hc/en-us . You chances are will need to open it up and see what kinda PSU it was on endings.

Is there an official firmware fix for this for S4 or S5? https://bitcointalk.org/index.php?topic=562238.msg11533376#msg11533376Would rather do that then use a 3rd party firmware, also the stratum method is a bit tricky to keep up 100%

Hmm. You'd be able to visually see if they changed as the S4 fans are distinctively unmarked. I think its an inherient problem with the fan rather than a life based failure as they do tend to give up at random points in their lifetimes. Not at the start, not at the end, just random.

I was monitoring my mining rigs and see one s4 offline, when I check on site, It's looks and smell bad... When I open it, see that surprise. In that site I have 4 s4 running, and only this one have problems, dont know more, but take care!

Looking at it from the front, in the s4, which board is which chain? One of my original B2 s4's is acting up and finally failed in a manner that kept the controller/GUI accessible. Says that chain 3 is all ---------- Cheers!

I too have ---- on chain 3. I'm assuming it's the psu since I haven't seen it pull more than 1000w at stock speeds. Awaiting a proper replacement to test.

Someone made a text diagram early on in this thread but I can't find it, and my S4 is probably different to most as it was an early one. The dead board might be highlighted by no LED activity though, worth a look.

The dead board might be highlighted by no LED activity though, worth a look. Tried that. At least for the versions that used PCIe power connectors like this one, there are no LED's on the boards. There *is* a row of very tiny ones on the controller board that could serve the same functions but is no way these eyes can see what they are labeled. As usual after it has gone down, after a power down and short rest it again came back up at full speed. The 2 other times it went down the controller was dead - no lan plug lights, no blinking CPU light, no red light. To cover other questions, all fans are fine, free spinning, no axial play to the blades. Temps 55-59c (room is 90F). Psu light is green.

Or is it not running at all during this time?
