Title: New S19k Pro Stopped Working after 1 week Post by: tuaris on January 08, 2025, 06:37:00 PM It was working fine for about 4 days. Put it on sleep mode about a day ago, and turned it back on. Now, it's giving this:
Code: 2025-01-08 17:51:00 no board pluged in socket 432 Also noticed this in the historical log Code: 2025-01-05 19:04:20 chain[2] asic[5] [215] [0] What happened? The room temperature never exceeds 75F, and the current room temp is 61F. Other S19k's still humming along nicely. Did I receive a bad unit? Firmware Version Mon Mar 4 16:03:40 CST 2024 Already tried the basic troubleshooting (reboot, factory reset, power cycle) Title: Re: New S19k Pro Stopped Working after 1 week Post by: tuaris on January 08, 2025, 06:45:21 PM Applied a firmware update (Antminer-S19k-Pro-merge-release-20240409060820.bmu), now I get:
Code: 2025-01-08 18:42:54 pulse_mode = 1, ccdly_sel = 0, pwth_sel = 4 So I got a unit with a bad fan? Is the ASIC fine? Title: Re: New S19k Pro Stopped Working after 1 week Post by: philipma1957 on January 08, 2025, 07:14:50 PM you lost a fan it happens. buy a fan and replace it.

Hmm, maybe just getting the fan is less trouble than trying to work with the vendor I purchased from. I wonder... I have a ton of spare fans from L3's and S9's. Will they work here?

Will they work here? maybe the s9 fan is fast enough. if it tops out at 4500 rpm it will likely not work but if it goes to 500 or more it should be good Title: Re: New S19k Pro Stopped Working after 1 week Post by: tuaris on January 08, 2025, 10:05:46 PM It's surprisingly difficult to figure out what fan is what and there is a serious lack of information about it.
According to Bitmain J12 = fan_id = 3 J13 = fan_id = 2 J15 = fan_id = 0 J14 = fan_id = 1 But I have J11, J12, J13, J14, and according to the labels on the control board J11 = Fan 1 J12 = Fan 3 J13 = Fan 2 J14 = Fan 4 http://download.morante.net/unibia/other/ANTMINER/20250108_145904.jpg So do I assume Fan 2 = fan_id = 1 = J13 = Rear0 = bottom back? UPDATE: trail & error results: J11 = fan_id = 1 = Fan 1 = Front0 = bottom front J12 = fan_id = 0 = Fan 3 = Front1 = top front J13 = fan_id = 3 = Fan 2 = Rear0 = bottom back J14 = fan_id = 2 = Fan 4 = Rear1 = top back Title: Re: New S19k Pro Stopped Working after 1 week Post by: BitMaxz on January 08, 2025, 11:51:15 PM It seems according to your logs it is a front0 fan that doesn't have RPM
So there's a slight difference from the result you edited above. fan_id = 0 = Front0 = top front fan_id = 1 = Front1 = bottom front If I'm wrong, you can also try to check the right location of the fan under the miners status, or a better way is to remove the fans one by one and then look for the logs to see if there's a change on the RPM to all fans so that you know which fan exactly is the broken one. Title: Re: New S19k Pro Stopped Working after 1 week Post by: danieleither on January 11, 2025, 07:24:28 PM With even a handful of miners it is essential to carry spares. It is not worth returning a miner for faulty fan or PSU, because they are so cheap and you'll lose more in downtime, plus the risk of damage in the post.
I have approx. 200 miners total across 5 small farms. I reckon I get through at least 50 fans and 5 PSU's each year, and 1 or 2 control boards. I'd recommend to keep as spares: 1 PSU for each 20 miners (with min 1 in stock at all times) 1 control board per 50 miners (with min 1 in stock at all times) 1 fan per 2 miners I buy all my spares from ZeusBTC (import from China).

Yeah they toss fans like mad so its good to have them. once you pull a dead fan and you are certain it is dead. cut the power cable from it as close to the fan as possible and save the four wires attach to the connectors. you wont mistakenly try the dead fan again. and once in a blue moon you may need the four wires and the white connector Title: Re: New S19k Pro Stopped Working after 1 week Post by: mikeywith on January 19, 2025, 11:29:26 AM With even a handful of miners it is essential to carry spares.
