Sure sounds like a contact issue. Next time you might even try the contact cleaner DeoxIT.

I have a spare hashing board and I tried to fire it up today as one went bad in one of my S9s. It didn't seem to work so I tried only that one hashing board (with all the others disconnected) and I get what you can see here:

https://www.dropbox.com/s/2sbe5lv6rt2p7lp/28693795_1799031853441185_1686200933_o.jpg?dl=0

I tried everything I could think of (firmware update on the controller, different power supplies, restarting, resetting, just waiting and letting it run for two hours...) but nothing works. Is this a bad hashing board? Or is it possible that it's not compatible with my (newer) S9s?

The hashing board is March 2017, so it should be auto tune (it has a sticker with "L1" on it). The controller is version 1.2 from January 2018, with the latest firmware.

The red LED on the hashing board is initially on when I turn the miner on, but then it goes off and never turns on again (until I restart the miner).

Math doesn't care what you believe.

How long did you wait before capturing that image?

I'm having this issue aswell, and looking for some help! Cheesy

After I changed the mining config (pool) on 12 S9's, one of them wouldnt start hashing again, and is not showing hardware version or BM miner version on the overview status page.

Info:
Code:
S9 model: 13.5 TH/s
Original filesystem ver: Fri Nov 17 17:37:49 CST 2017
Original logic ver: S9_V2.54


I can't remember if there was any errors in the kernel log when I was running the original firmware that came with the miner.

I've tried 2 different firmware versions from Bitmain, the one released in april, and the one released in november.

When running the firmware from april I get a error like "Connection to socket failed", or something like that.

The firmware from november on Bitmains site is not the same as the original one, but they were issued on the same date.

When running the newest firmware I get:
Code:
Filesystem ver: Fri Nov 17 17:57:49 CST 2017
Logic ver: S9_V2.55

Seems like this firmware was compiled 20 minutes later than the original firmware.

Anyway, when running the newest firmware, I actually get an error in the kernel log that makes sense:

Code:
get fan[5] speed=1920
get fan[2] speed=4800
Fatal Error: some Fan lost or Fan speed low!

Seems to me both fans are spinning as normal, there are no damages to fan cables or connectors, and I also think its kinda strange that it has been working fine since 11.dec 2017, but stopped working at the same time I changed mining config/pool.

I've tried different pools and ports with no luck, I've tried changing TP-cable, I've let the machine be disconnected from power for several hours, and 3 different firmware versions which gives different errors in kernel log.

Do you guys think its actually the fan, or something else?
Where can I buy a fan that works with the S9?

Any other suggestions?
