Netgate XG-7100-DT PWD LED remains red
-
Hello,
I'm in the unfortunate situation that my XG-7100-DT won't power on anymore the PWD LED remains red, I've tried to add an M.2 SATA SSD (as the onboard eMMC could obviously fail quite easily), tried a new power brick with the same power rating and also tried the usual power reset and holding down the reset button to no avail. There's also no output via the serial port and the fan does not spin up.
Any ideas on what to do?
Thanks in advance! -
Hmm, it never shows anything but red?
-
@stephenw10 Correct, no matter what I press or do. It goes red when plugged into power and that's it.

@Expletive1500
Did it work before you installed the M.2 SATA? -
The only legitimate situation I'm aware of that can present like that is if the detected memory changes. So for example if you add or remove a DIMM the new total RAM size has to be re-trained and it can take a surprisingly long time. During the retraining the LED remains red and there is no console output. You only see anything once the POST has completed.

Shouldn’t the fans start in that case? -
@w0w Hello, sorry if it wasn't clear in the OP.
It stopped working shortly before installing the M.2 SSD, reading about Netgate appliance failures online made me think the reason it had failed was due to the eMMC going bad. However after seeing stuff like the fan not spinning I'm assuming something else has gone wrong. -
@stephenw10
Thanks for your reply, I haven't touched the memory in the appliance at all. I has also been continuously powered on for ~12 hours now so I doubt re-training is the issue. -
@Expletive1500
I don’t know if, on this particular model, a faulty eMMC could prevent it from starting up. The only way to check this would be to desolder it completely. Of course, this is a non-trivial task, and you might need to find a service that can do it. That’s assuming the problem is actually with it — which, in principle, is quite possible. -
@w0w
Interesting, I would assume I could still reach BIOS even with a faulty eMMC and just reinstall pfSense to the M.2. -
@Expletive1500
There have been people on the forum and on Reddit who desoldered the eMMC and the bricked device started up. However, I believe they were talking about the 2xxx and 4xxx series, but I’m not entirely sure.You can also buy a working used unit or motherboard on ebay

Oh good point. Yes, it would come up with the fan at full speed whilst it's training. That seems more like a power component failure then if the fan never spins at all.

@Expletive1500 I have personally experienced 3 or 4 devices that appeared to be completely dead when the eMMC failed, and there are other posts about the same issue. The devices work fine once the eMMC is desoldered.
The task is not too difficult - you just need a heatgun (a hair drier might also work), some aluminum foil to shield the surrounding components, and something to gently lift the eMMC chip off the board when the solder melts.
If you are going to replace the device or the board anyways then you have nothing to lose by trying to remove the eMMC chip.
I believe the eMMC chip is located by the CMOS battery and will likely be labelled "Kingston."

Hmm, sorry l, but using hairdryer is a bad idea, untill you are using some industrial heat gun to dry your hair. You need more power then hairdryer can provide, I think.
There are other extreme methods, but they require skill. I have removed some chips using a torch lighter and flux, but you have to be very careful with this. This is in the realm of so-called “Pakistani repair,” where they even desolder using a candle.
