Thanks for the help on pools - Kano seems like a nice pool...
BUT managed to trash the control board somehow - it is not booting properly. Ethernet link LEDs come on, but neither the green nor red LED light up. The fans stay at their low idle speed. Disconnected all the hashing boards, and just trying to boot up the control board. The static IP is unreachable and the DHCP server is not seeing a DHCP request either.
Trying to recover the FW via SD, still figuring this out... or better by TFTP? The SD instructions seem old - they reference the S7 firmware, while the S9 firmware has a different file layout.
Has anyone managed to connect to the /dev/ttyPS0 console via the pin headers? Is this TTL 5V RS232 or "real" RS232? The speed seems 115200bps as per a previous dmesg dump in the thread.
If anyone has any hints, they would be appreciated.

Just *how* is an obvious failure of the hash board Vcore regulator -- probably the MOSFET's shorting -- the fault of a PSU? Just what in a PSU do you assume could have prevented this?
The Bitmain PSU can supply up to 133A continuously and probably at least 10-15% more before tripping out, the combined maximum current rating of 3x PCIe connectors is only 81 amps. Vcore regulator blew, all power took the easiest path - through the short circuit - and so yes, the connectors and wiring smoked. For what it's worth, I have 25 of the AWP1300 supplies and have had ZERO problems with them. Don't know about the newer APW1300+ but the older ones are very well made.
Now should all miners have a fuse between the power sockets and Vcore? IMHO yes they should but that is just speaking as an Engineer with over 50 years of dealing with power electronics...
Yes sir.. My power supply is still working with 12v.. that's odd. With your years experience in electronics. what can you suggest? Do I just put a 80a fuse between the power supply and miner? How do I put it? one fuse for the positive, and one fuse for the negative? I have 3 more S9's coming nxtweek. I can surely have a super advice from you sir. Thanks.
Not going to retyped it all again so ref https://bitcointalksearch.org/topic/m.17968291
Done that way each cable is protected plus easier to wire and fuses cost less.

Kano or Slush for example..
What was your setup when you got this - #391994 at solo.ckpool.org ? Nice!

What are the recommendations on pools for a single S9 miner at present? Eligius seems to be de-funked - it was a nice free anonymous pool with useful stats...
Bitmain's pool? They seem to have a charge. P2pool is not an option at the moment.
Thanks for any info.

Anyone noticed that bitmaintech's site is now unsecured. Their SSL cert expired? Any word from bitmain itself? Are they even aware of this?
--edit-- nevermind, it seems bitmain is not using the bitmaintech.com domain anymore that's why.

Received the "Feb 20 shipping" S9 miner yesterday....
I know you are all going to laugh, but this thing MAKES A REAL LOUD NOISE. It is unbelievable!!! Had I known....
I know you are all going to laugh, but this thing MAKES A REAL LOUD NOISE. It is unbelievable!!! Had I known....
Can somebody confirm whether it is "normal" that the fans run at about 4200rpm with an ambient of round 25C. Hash boards are at 77C and 83C hashing away at 4690 and 4680 Gh/s. There is a high pitched whistling sound.
thats about the norm for the s9 autotuners....they are all very noisy.

The EVGA 1600s are rated for continuous loads so that's plenty. I've read the reviews and the PSU can actually handle temporary peak loads up to 1700 watts (though it's terrible for the PSU). Proper functioning S9 shouldn't draw more than 1400 watts at the wall.
Thank you for this input. Im eyeing on the 1600w now.

I use a combo
1x 1300W -> Board 1 + 2
and
1x 1000W -> Board 3 + Controller
Running on 220V.
1x 1300W won't be enough
Will buy the 1600 instead? it will be enough i think?

My PSU is the Bitmain APW3+-12-1600W, It says it has every protection. but it failed. 
A waste of money.
A waste of money.They are $150-ish. The EVGAs are $300 - $400. I go higher end on those.
Man, that really stinks. I wonder what caused the problem. Try calling the Colorado office for Bitmain warrenty at +1.844.248.6246???
I contacted their support, asked them why it happened, They said it was my PSU giving irregular voltage. They then asked me what PSU im using, I informed them its their Bitmain APW3+-12-1600W PSU. I'm waiting for a reply now.

Get one of these 1500w server power supplies. Mining is what these puppies were made for: http://www.ebay.com/itm/684532-B21-684529-001-HP-1500W-CS-Platinum-Plus-Hot-Plug-Power-Supply-/252627974019
Then get a breakout board to make it work with the miners: http://www.ebay.com/itm/Breakout-Board-Adapter-for-HP-1200w-DPS-1200FB-Power-Supply-Bitcoin-Antminer-/231948229211?hash=item3601311a5b:g:f0UAAOSwcvdXO6By
Not the best of ideas to go with a power supply that is meant to be used in home computers, pushed not nearly as hard, for not nearly as long as you'll be using them for. Plus these are WAY cheaper.
Thanks for this idea also.

Your P/S is a brute. Short-Circuit protection should have kick-in and save the day.
A fuse should be mandatory in any high power design. In this case, miner.
Didn't see any so far, and many manufacturers out there.

Ah I just read this, it's the shit power supply Bitmain sells that fucked up, not the miners. I guess that's a relief that it's their psu's and not miners that are randomly catching fire lol. Makes sense I suppose.
Definitely go with some good server power supplies in the future.

How do I add a fuse between the PSU and Miner? Do you know any electronics? How many ampere should I put? I have 3 S9's coming. I would like to protect it. Its very frustrating to see my investment just get burned. tsk.
Simple equation is Power in watt ( P ) = Voltage ( V ) * Ampere ( A )
or
P = VA
or
A = P/V
1600W / 12 V = 133A
133A / 3 Boards = 44A
Rules of thumb you rate your fuse x2
80A Fuse with enough DC voltage rating will do a good job.

Need a breakout board and extra cables
I didn't fused mine. I use high quality EVGA 1300 supply with working protections.
Over-Voltage, Under-Voltage, Short Output, Over Temp, Good voltage regulation and 10years warranty.
Expensive but I sleep better.
For few extra bucks, manufacturer fail to add safety to save money.
Will definitely do this. thanks for the info. Is a 1300w PSU enough to power the S9?
Will this do?
