Just got 3 new s9's

two are fine and on slushpool.

the third is having controller issues.  I connect it to the network and SYSTEM OVERVIEW comes up and only ADMINISTRATION - MONITOR - UPGRADE are accessible.

All other tabs give me CONNECTION REFUSED.

I have disconnected the hashboards, same issue. 

I have tried to do a reset.  same issue.

Tried to ssh into the machine to turn off.  same issue

Should I try to do a firmware upgrade? If so, how do I choose the correct firmware from the bitmain site?

Would really love to get this last machine up.....

update:  i pushed the reset for 15 seconds and it started working, so up updated the firmware while it was working.  then everything seemed fine.  after 30 seconds it started misbehaving again.

all system information, in SYSTEM OVERVIEW, is blank

now it's "kind of" started working. 

system info popped up, but hardware version is blank

I was able to put in pool information and it appears to be connecting. 

really strange.

web interface crashed again.  everything blank, and most tabs unreachable.  still connected to slushpool, but speed not that good

I had four delivered today and ONLY managed to get on running.....

I can connect/see all system details BUT the boards are DEAD ? They only had constant red led when turned on booting, othey did noy FLICKER whentrying to mine ?

I warmed one up on my heating radiator and it worked ????

The other 3 i have tried do not show the cards ??

Bloody hell Bitmain !

 >:( :(

fortunately I was able to get the interface working long enough to configure the machine.  at least it is online while i wait for another board

All my interfaces are fine on my four..

I can add pool details etc (slushpool and they all show)

I just booted another one up and had NO red leds on the boards ?

Everything else is fine just no speed/cards/chips showing ??

How do you know it;s the board ??

when I access i get this: https://photos.app.[Suspicious link removed]/7k7bf9RVFv6MvQXu1

Links/pics not working, there is something up with this batch !!! Bad soldering on chips..

Not happy, i've started on the S2...HATE having them sitting here !!

I think bitmain mines them for two months to weed out bad ones, I would be surprised if they shipped more than a few rejects per batch.

OP it sounds like you have a control board issue.  Can you swap the miner over with one on a working setup - meaning use the power supply and Ethernet cable from a known good unit to prove the problem is not from power noise on that supply.

I have 2 out of 4 working now, plugged one in which i played with for hours last night and it powered up ?

The issue is the boards, they are not going through self check/autotune, no solid leds, then no flickering leds, then they are supposed to flash board 1, board 2, board 3, bit more flickering and then ON solid and green NORMAL status led flashes on I/O board..If not then ur stuffed ??
