MinerSource Order of Prospero X3 finally arrived

I don't see how MS can be legally selling devices without any US certifications like FCC.

Not sure - but you can see the labels of the sunshine ap188 made by apluspower.cn - and it's missing quite a few logos that are normally on all the other dell, hp, delta, ibm, sun, etc server psu's that i've seen.  Short of those little 360w ones that were used for gridseeds

I put a PSU from another unit in that machine, and it reads alarm/fault - and the psu that shot sparks out works fine in a different unit.

So i've concluded that rather just being a power supply - it's the actual miner.  anyone know how to reset the bugger

I would start by looking at the backplane caps, and removing them if they look like they've failed.

If no help is to be had there, I would then remove all but one of the hashing modules from the backplane and see if it will start up like that.  If so, reconnect another, etc, and see if you can isolate one of them that pisses it off.

The "ageing process" lol

BFL move. Has anyone complained to the FCC?

Thansk I'll give that a shot. I have removed all the caps - I have 5 other machines running fine with the caps in place.  This board is v4.0 not v4.1 as others are that are working fine.  this one has a silver colored main bus as opposed to the others with copper colored.

Did just that.  It worked.  Found a dead module.  Another module has 1 dead chip and 1 live chip.  So I've asked BlackArrow to send out a few replacement boards and I'll just swap the heatsinks over.  Let's see if they will do that.   I'd contact MinerSource, but since they don't respond to emails, private messages and they cancelled their phone number, I'm not sure how to get a hold of them.

Update: while MS normally has not responded promptly, I got a response about the faulty hashboard and he said that they have replacements.  So perhaps there is some light in all of this.
