Hi,
Im trying to make my Antminers a little bit quiter. Can you give me advice, which diameter is better for the hose?
I want to use 5m / 16ft or maybe 10m / 32ft hose on each side of the miner . Will it be able to push that much air if the hose is 5in?
Whats the advanteges/disadvanteges for 4 and 5 inch hose.
Thanks!

Hi fellow Bitcoin Miners,

I have a problem with my brand new Antminer S9. After properly connecting miner to PSU and ethernet, my miner is not working. The Hardware Version and BMminer Version in the Antminer System Overview are empty. I have a FW Fri Nov 17 17:57:49 CST 2017. I tried reinstall firmware from bitmain website, restarting, rebooting, reseting but nothing worked.

The red lights on boards are turning on and off. The green normal LED on front is on. I have your PSU AWS3++ in 230V socket.

And in kernel I found this: bmminer not found, restart bmminer ...

Please, what should I do?
