How do i turn ant miner 9 off through the computer interface? so i don't need to plug it off directly from the socket

is this a theoretical question?
you don't plug S9 into the socket to start with, you connect it via PCIe cables to power supply unit (PSU), which typically has an on/off switch.
it is fine to switch antminer off by switching the PSU off, but wait minimal of 20-30 sec to switch it back on.
you can only reboot the software via gui as far as i remember, although if you don't provide correct pool info, it would not mine, but I am not sure if this is good for the miner as boards might heat up anyway (not sure about the latter point).

Hey team,

I noticed my S9 today (for a few hours) experienced a drop in hashrate for 1 board. It went from a typical 4600 GH/s down to 1250 for about 3 hours until I noticed. There were no xxx or anything. I restarted the miner and it is hashing like normal again. I will continue to monitor. I've had the miner for about 2 weeks.

Should I be concerned? Do you think the hashboard would have recovered on it's own eventually? Do you think it would have been bad to continue without restarting?

Thanks

I would guess that the temperature of the chips dipped too low. It is a common problem for the S7 as well. You will not usually see any Xs when it happens either.

You may be right the ambient temp in my garage is 4 deg C at the moment. I am working to increase the ambient temperature.

Cheers

I wonder if you could redirect some of the heat output back into the input.

When I had the same issue on my 2x S9 both boards died and I sent them back for under warranty repair, now they are working just fine, but couple days ago my other board died and I have to pay for repair because they are out of warranty. Keep an eye on it you'd be lucky if that was one time accident, cheers!

PS. does anybody knows where are they going to restock S9s ?

Just thought I'd update here on my repair process with my Batch 23 Antminer S9.
It arrived last week and this week 2 boards stopped operating. I contacted bitmain and was told to return the unit to Hong Kong as per usual. After I complained about the shipping cost being too high bitmain offered to cover the return shipping. So far I must say the service is excellent and did not expect this from bitmain due to the high complaints about warranty. I was pretty shocked when they said they would pay for all round shipping. Great service so far and really gives me hope that they still care about customers.
I hope other people dealing with repairs get the same treatment as this

That is stunning I have never read this from anyone but you.

I'd assume people would usually want to keep it on the down low but I felt the community should know. If you would like proof I'd be happy to provide it to you in a PM Philip. The reason I won't provide it here as it has sensitive information but will be happy to show it to a trusted member.

Edit: I've purchased 18 Antminer S9's in the past 2 months so maybe that has something to do with it ? I don't know just an idea

Did you receive your repaired S9 back from Bitmain? How long did the repairs take?

No not yet. Only shipped it out today. Will keep you guys updated

Thanks for the tips gentlepeople. I will go look for some cheap insulation or consider a decent space heater that kicks in at a certain ambient temp.

I did already notice a drop in hashrate this morning since it got really cold last night, so I'll act on this soon.

Regarding heating the house with mining, it is probably not enough to provide 100%, more like 30-50% (if you are below 3.5-4kw).
I am doing a pure "experiment' right now with about 3.4 kw plus the rest (light, TV, cable box, etc. etc).
Temp are 72-73F in the house with 52-54F outside. Did not use the NG heating so far.

The specs for the S9 state the ambient operating temperature should be 0-40 deg C.

I live in a cold place and my sole S9 is set up in my garage. It's getting colder and I expect the ambient garage temperature to drop below 0 deg C soon (its 4 deg C now).

Are there serious risks to run the miner below 0 deg C? I was thinking a few deg below wouldn't be a huge deal, but maybe condensation can become a concern?

Thanks

catastrophic failure was less likely when i had this situation with the hosted S7 (in fact, they did not fail), but they could go down and then it would be difficult to restart them in the same place without heating them up a bit first; someone with SP20 in a cold/wet space invented the technique of heating them up with a blow dryer on high heat. Early warning would be dropping out of one board or a deep decrease in hashing (it would not even show XX sometimes, just drop speed). I hope that this helps.

Condensation would be a concern. Also any oil or whatever in the fan bearings would thicken and put the fans under more stress. How much more I couldn't say.

Have you thought about buying some cheap insulation of some kind and lining the garage to keep some off the heat in to avoid the cold but still keep it cool for the miner?

Try mining in your garage and monitor it's hashrate and etc

Yeah I am doing this but I don't want to risk destroying my equipment by allowing a catastophic failure.

So any input on the associated risks or real work experience is much appreciated

I want to avoid buying a spaceheater and wasting money on powering it.

So assuming the miners keep the area at >60-65F, as a backup set a space heater to a bit below that so the heater only comes on if some miners go down and stop making heat or not enough heat if it's really cold out (and insulate)...

I have heard from many people that in winter they are mining outside. I think mining below 0 degree C isn't good idea because if there is freezing in that area, than it maybe hurts fan. Usually when mining rigs are in cold place and they are protected from rain andsnow, there isn't problems but of course everything isn't same. Try mining in your garage and monitor it's hashrate and etc

WOW lucky on u free posting all around. But as long as the warranty process is good and fast..i dont mind pay shipping. its been hellaaa shipping back and forward for s9 hashboard B13 for last 3 months to HK. So far good warranty service.
