Antminer S9 Not working

[agriffin2002]

I have an Antminer S9 that had a chain that stopped working.  The web UI was only showing 2 chains working.  I restarted it a couple of times with no success.  I went to https://shop.bitmain.com/support.htm?pid=00720161126080548570Q2tDBXAH065D and downloaded a firmware update to try and even tried the Antminer Fix .tar file first.  My web UI went not showing any data of any sort in it.  I tried the reset of the Antminer, but that isn't doing anything.  Now I can't find it on the network.  It runs, but it doesn't seem to be hooked into the network at all and I have it hardwired to the router.

Any help please?  Is there anywhere that I can get replacement cards if one of the cards is bad?  Is there anyone in the US that does repair of Antminers?


Thanks!

Power it down and try switching around the ribbon cables.  See if the same chain fails (bad hashboard) or if whatever chain is on ribbon cable X fails.

The PSU has no ability to communicate with the miner.  This hypothesis is probably not true. 

I do understand how frustrating it can be to have an ant down, and I too have made many incorrect conclusions when debugging rigs.  The best way to figure it out is to swap the questionable ant into a working setup if you have another ant from a previous batch.  If the known good ant can't run on setup #2 and questionable ant runs fine on setup #1, then setup #2 is bad and you must change things one at a time in setup #2 until you pinpoint the issue.

It sucks, but that's debugging.  Spend an hour working methodically, and you'll be better served than 4 hours flailing angrily - trust me, I've done both.  Many times.

Be sure to do some tests on your ping and on your network before troubleshooting, too. The issue may possibly lie on the psu code.

Could be a bad hash board or controller defect.
Any luck with getting it working again?
