Re: [Soekris] net6501 error led / no console / doesn't boot
Interesting and thanks for the picture. Does anyone know if it's possible that replace the passive cooling before the board breaks down? At least after running now a day, I can compare to the old passive cooler. The new one is better, my net6501 is running about 5-6 degree cooler. I've also noticed, that the EG20T chipset is a never revision (old rev 1, new rev 2).

Re: [Soekris] net6501 error led / no console / doesn't boot
Soekris just replaced a 2+ year old net6501 of mine that had similar symptoms. And there have been several similar cases mentioned on this list. Just a quick update.. My soekris net6501 has been also now replaced. All symptoms are gone and the new mainboard is working perfectly fine.

Re: [Soekris] net6501 error led / no console / doesn't boot
I had a dead net6501-30 last september. Worked fine since I got it in October 2011, but when I was switching back and forth (trying out) m0n0wall and pfSense, it suddenly didn't want to boot anymore. Taking the power off for a few minuted made it work again, but it went worse with every reboot. I was able to enter the umanager, but it wouldn't boot anymore. So I RMA'd mine with Soekris Europe and got a new one back. The old one had the small back heatsink while the new one has a much larger blank aluminum heatsink.

Re: [Soekris] net6501 error led / no console / doesn't boot
Hopefully RMA'd boards will help Soekris folks analyse what's gone wrong with the hardware and whether it can be worked around via BIOS update. Since the devices don't show any warning symptoms (are running normally) and the boot failures for some at least are initially intermittent, there's a small chance there might be a different power on sequence that the bios could implement to resusitate these boards. Relatedly, it might be the power on sequence that the BIOS is employing that is frying components and as such a newer, gentler start up might be able to preserve existing boards. Would be nice if someone on the soekris side could provide an update as to what their current thinking is / what they advise customers should do. Should we all RMA our dead net6501 boards straightaway? What's the advice/plan?

Re: [Soekris] net6501 error led / no console / doesn't boot
Hi I have shipped in 4 boards with the exact same issue to soekris in Denmark last week. And I have one more lying around with the error. Some of our clients have seen this issue, where it suddenly stopped working, and could then not boot back up. We have spend a lot of time to go out and fix at random times, and replace the boards. Sometimes after they have been turned off for a while they will boot again, but then right after a power cycle, go dead again. So I had gathered a few from our installations, and where beginning to become a big problems as more of them die. While they have this issue, it can normally also see the Ethernet diodes flash randomly at low power. They all have similar serial number, and have the black heatsink that is just a flat plate.

Then used that bios uploaded into flash to update the uManager itself, which incidentally also worked.So I guess that means that flash is okay, as is the uManager. Can't say the same for the bios or the board, though. Still same booting problems. Apparently the hardware turns on the RED led and the bios turns it off once it's ready launch the OS. I'm guessing something in the bios's board bring up sequence is getting stuck - maybe it resets a device and then polls a register forever or somesuch. - just a wild guess.

Re: [Soekris] net6501 error led / no console / doesn't boot
I've already contacted my seller and he replied, that RMA should be possible without any problems. But currently, he is out of stock and waiting for new mainboards to arrive. So my RMA is still waiting. My net6501 is also running in a rack case. Today, after several days without power, I've tried so start the net6501 again. It also seems, after it was a time without any power, its starting again. But only a few times, than the problems started again. Running a net6501 with only onboard SSD and WiFi works in max 50/50 situation. So not every start/reboot works. Sometimes it's completly dead again. When I try to connect any PCIe-card or attaching a additional HDD, which was working perfectly fine before those problems occurced, its even more worse. It's nearly every try playing dead or not booting. That sounds a little bit, like the mainboard has some troubles with the power. At least I know, it's not the PSU, as I tried two different PSUs, which gave the exact same results. I've also measured the current power, as the manual states max 30w. When my net6501 was able to boot without any problems, it showed about 10-15w max. So this is far away from the max of 30w..

Re: [Soekris] net6501 error led / no console / doesn't boot
While they have this issue, it can normally also see the Ethernet diodes flash randomly at low power. That's interesting. I've something similiar. A character LCD (40x4) with an USB-Interface is connected to my net6501. When the net6501 does not boot or is completly dead, I can see the status LED of my LCD flashing. Like your ethernet diodes. Normally, the LED does never flash, but is turned on all time, when it's connected via USB. What operating system is everyone running who has had this problem? And have you updated recently before the failures? I am using Gentoo Linux. My updates meant, that I am justing updating my linux kernel and have to restart. Nothing special IMHO. And yes, this was working before fine. Cheers Conrad ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
Re: [Soekris] net6501 error led / no console / doesn't boot
Hi Martin, On my dead board I have not observed the ethernet leds flashing randomly - I essentially get all synchronized flash when reset button is pressed and then all ethernet leds off. That said, I wasn't watching it too closely before it died :( ... Since then I've been testing the dead board on my lab power supply - it's the type with digital read-out where I can set voltage with a dial and observe both voltage and current draw and I can say with confidence that this problem is not related to power supply. At the moment my backup board, a net5501, is working admirably .. my config requires three or five 100BT or gigE ethernet ports .. not sure what other fan-less alternatives there are out there .. --Andrew On 2015-01-13 1:42 PM, Martin Dahlem wrote: Hi I have shipped in 4 boards with the exact same issue to soekris in Denmark last week.

Hi Andrew! I did manage to get to uManager - that was sort of a baud issue At least, I can't get even so far. I've tried every baud from 9600 - 115200 (this was set by me). After I've left the net6501 for about 2 hours without power, the device started booting again. I was able to enter uManager. But a reboot later, thats it. Now, the device isn't anymore again responding. It's dead again and no serial output or uManager.. Let me know how your RMA goes - no sense in both of us paying for shipping if it's a lost cause. :) Soekris did respond fast.

This appears to be the same problem reported on the mailing list a few times, e.g.: http://lists.soekris.com/pipermail/soekris-tech/2013-September/019077.html http://lists.soekris.com/pipermail/soekris-tech/2013-November/019110.html ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
Re: [Soekris] net6501 error led / no console / doesn't boot
Hi Alvar, I’ve visually inspected the board and the caps all look good. In fact the board, living as it has in a soekris case looks brand new. Apparently ‘no fan’ == ‘no dust’. So I’m going to rule failed cap. I think it’s more likely the BIOS/firmware is toast. It’s a shame really, as the board is otherwise perfect. :) Wouldn’t it be nice if one could short a pin and have it reload default/failsafe BIOS from a PROM. :) Failing that I suppose we’re in JTAG country. Does anyone know if soekris makes jig for that? —Andrew On Dec 18, 2014, at 7:03 PM, Alvar Kusma al...@raamat.polva.ee wrote: I then brought the unit over to my lab bench and hooked it up to my variable power supply.

[Soekris] net6501 error led / no console / doesn't boot
Hi Folks, My net6501 had been humming along happily since it arrived in 06/2012 .. I don’t often need to restart it - the last time was 91 days ago following a protracted power failure my UPS ran out of juice. At any rate, last night I noticed that a file system had overflowed and so deleted a bunch of files and restarted a few processes, the file space didn’t come back straightaway and so I thought about restarting a few more things but then it was late and had been a long day and so I thought I’d simply reboot it. That was sort of a bad decision, as 4 hours later I finally got to bed. Here’s what happened. I rebooted and the board’s led’s cycled as normal but then only the power and error led remained lit. The console was catatonic. My first thought was that the attached SSD had calved, and so powered off, unplugged that, powered on. Same result. I then brought the unit over to my lab bench and hooked it up to my variable power supply. Set the power balance at about 12v and powered on. Same. Held the reset button down until the unit powered off. Released and held it in again until the unit powered back on. Same result. At 12v I then tried all of the console baud permutations - 9600, 19200, 38400, 57600 and 115200 to make sure that I wasn’t doing anything silly. Still no output, and just the two leds - the power and the red error. Grabbed a regular 2.5” laptop drive, plugged it in to the net6501 and powered on again. The drive spun up, no problem. Took the SSD used in the failed net6501 and plunked it on my ‘backup’ net5501 via an external eSATA enclosure and up the net5501 came - config was a bit upset about the change in interface - em0 - vr0 and disks da0-ad0 but otherwise perfectly functional. Phew. With internet access restored courtesy of the net5501 I looked for net6501 error and found a thread on this list that recommended ‘+++’ on the serial port to get to control mode or somesuch. No output at the any of bauds, with complete power off in between each test. The cpu was warm but not hot, normal really, and the board was drawing about 0.3 amps at 15v, but it was clear that the network ports were not powering on. First I tried a ge loopback plug I’d made a while back in each port - none fired up. Then I tried cabling each port in turn to a gigE switch and neither side (the switch nor the board ports) lit up. So now what? Well. I started ramping down the voltage, and the current increased as expected. But then something magical happened at 5v, 3 of the network leds (the three that had been in use prior to the failure) lit up. Still nothing from the link leds though and still no console at any of the bauds, nay any effect of ‘+++’. And so that's where I’m at. Kind of out of ideas, and not sure of how much more I can diagnose with this little fellow. I suspect that something in the BIOS power-on sequence has failed. The strange thing (and what gives me a bit of hope) is that the board was running perfectly until had decided on the reboot. Perhaps the BIOS has become corrupted? Does anyone know if that’s possible and if so if there’s any way to fix it - maybe a cheap and cheerful JTAG jig? Any and all suggestions welcome :) Cheers, —Andrew ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
