Title: Antminer S9 Not Powering On Post by: cupell08 on January 27, 2018, 06:56:40 PM Hello, have an S9 that is not powering on.
Using AP3W++ on 110V. ( 220V being installed next week. ) Even powering on without hashboards connected (following bitmains troubleshooting guide) there are no signs of life with the controller board.. This suggests a faulty controller board according to their guide. Now do I order replacement controller board or am I missing something -- will the s9 refuse to show signs of life on 110V using ap3w++? Thank you! Title: Re: Antminer S9 Not Powering On Post by: VRobb on January 27, 2018, 07:11:07 PM You should be able to power the controller and a couple boards on 110VAC. Are you disconnecting the I/O ribbon cable coming from the board(s) not being powered?
Title: Re: Antminer S9 Not Powering On Post by: cupell08 on January 27, 2018, 07:14:04 PM Yes , disconnected.
Just trying to power the controller board as described by bitmains troubleshooting guide. Title: Re: Antminer S9 Not Powering On Post by: A.Delaney on January 28, 2018, 01:58:21 AM Is there power coming from the psu?
Title: Re: Antminer S9 Not Powering On Post by: Raymond_B on January 28, 2018, 02:07:22 AM Is the cooling fan for the PSU moving? And you've checked your breaker for the outlet?
Stupidly obvious I know, but 1st rule of troubleshooting; rule out the easy/obvious stuff :) Title: Re: Antminer S9 Not Powering On Post by: cupell08 on January 28, 2018, 02:19:12 AM Is there power coming from the psu? Is there a way to effectively test that? PSU powers on but I have not yet confirmed if it delivering power or not.

Stupidly obvious I know, but 1st rule of troubleshooting; rule out the easy/obvious stuff :) No fan / leds. No signs of life,, Breaker all good, psu does turn - antminer does not.

Also someone in another thread just said that the S9 will not post at 110V with apw3++ without sufficient wattage .. is there any truth to this?

Also someone in another thread just said that the S9 will not post at 110V with apw3++ without sufficient wattage .. is there any truth to this? I saw that, now I've never tried 110v, but the AP3++ will provide power on 110v (up to 1200W). And because you removed hashboards and still no joy I think it's something else. ***BUTT** I would wait for more experienced folks to chime in about that :) Title: Re: Antminer S9 Not Powering On Post by: cupell08 on January 28, 2018, 07:01:59 AM Is the cooling fan for the PSU moving?

Found this, be careful! https://support.bitmain.com/hc/en-us/articles/115004339274--How-to-use-a-multimeter-to-test-PSU Tried this and sure enough, getting zero readings with both methods.. Now my question is if my PSU is defective or if the PSU will not provide power at all on a 110V outlet? Getting 220V installed tmrw so we will see ... Title: Re: Antminer S9 Not Powering On Post by: VRobb on January 28, 2018, 07:34:39 AM Unfortunately if you're getting no output from the psu at 110VAC I wouldn't expect anything different at 220 unless the autoswitching circuitry is wonky.
Title: Re: Antminer S9 Not Powering On Post by: cupell08 on January 28, 2018, 03:41:26 PM So if my PSU is defective, can I attempt to run 4 individual 600W PSU's (one for controller board and one for each hashboard) since I have them sitting around.
Or should I just replace the APW3++? Title: Re: Antminer S9 Not Powering On Post by: VRobb on January 28, 2018, 04:36:36 PM You could do that, sure. I'd think 3 would be enough unless you don't have enough pcie connectors.
