Possible power switch issue?
So I've been pretty happy with my Apollo II, running it in solo mode and even pointing two Avalon Nano 3's to it right now.
Besides the SQL bug for the GUI, it's been great. Occasionally, I may need to reboot it as I haven't been sure how to work around the SQL bug and monitor the unit remotely.

Recently, when I reset my remote PDU switch to the outlet, the unit won't come back on. When I reset the power switch on the back of the unit, it would start to work just fine.
This happened a few times but now, when it reboots and starts to begin hashing, the unit turns completely off! It seemed the switch was acting as a safety, as if I barely touched it, it would "reset" and start to give it power again.

I decided to open the unit to see if I can see anything but everything looked great inside. For me, I decided to bypass the wiring inside to skip the switch and have the power supply go straight to the outlet plug.
After verifying where the wires should go, I disconnected the wires from the PSU to the switch and plugged it into the wall plug to bypass the switch. I powered it up now everything is working again and it has started hashing!

Not sure the quality of the power switch in the back of the Apollo II unit, but if needed, you can bypass it and it seems to work great now.

If you have random shut downs and resetting the power doesn't fit it, that little switch could be the issue.

We have had a few power switches fail and yours could be one of them. The issue seems to stem from people not plugging in the power cable all the way into the socket which causes the AC pins to overheat and eventually fails the switch.

Now that its heater season will probably send out another email to everyone to remind to make sure you are checking the AC cable for overheating especially when changes power modes from eco to balances/turbo

jstefanop,
I don't entirely agree. The issue does not always stem from people not plugging in the power cable all the way into the socket. Yes. maybe a few, but certainly not all. I have been the recipient of such units and I certainly plug my units in completely. As a matter of fact, I'm still waiting for a return for this very problem that's been over two weeks since you received it. And, I'm monitoring another that may also need an RMA. Just to let you know.

Regards

I'm with you PennyBit, this is a switch issue for sure. Since I own a RTX 4090, I've become OCD about plugging ALL my cords in fully until I hear a click, no matter what it is. Tongue

It was more like the switch was tripping out on the load, not on the plug issue. As soon as it began hashing and the watt/amps would go up, it would kill the connection while still "on".
Also, since you have mentioned in the forums about plugging the cord full in, I actually went back and double checked all my units. They were all fully seated...

shaotai,

Lol, I actually received the repaired unit this afternoon (without any tracking or notice from Futurebit). FedEx just showed up after I got an email stating I had a delivery coming today. Well . . . swell. Wasn't sure what I was getting or from whom. Surprise!

In any case, the unit has not yet been plugged-in or tested, but the switch itself is much firmer and actually "clicks" when flipped. The original was very soft and just kind of "rolled"over without making any click or "rocker-lock" feel. Just an FYI as it appears to take at least a couple of weeks for the repair and you have to pay for the return shipping as well.

Cheers!

UPDATE: 10/13/24

So far so good on the repaired unit. Been running between ECO & BAL for the whole day and no problems. The switch seems to be functioning as expected. No strange shutdowns or resets or any other issues . . . so far. And, the cords are inserted all the way Grin

. So, get your RMA and feel confident (and patient) that it will be repaired.

Cheers!

It seems like my switch is failing, as well. It will mine for a couple of hours and shut down. Then when I barely touch the switch, it powers back on.

Rather than returning for repair, is the switch an off-the-shelf part I can replace myself?

Just reply to your order email, if your switch is bad the whole assembly needs to be swapped out as damage is caused by overheating due to bad contact on the AC plug and that will damage other contacts on the back of the switch.

We are either swapping it out for you or can send you the whole socket assembly if you would rather swap it out yourself. It's not that complicated to swap it, but requires cutting off the tabs from the inside that hold the socket in so need to remove both the bottom and top covers.
