SG-3100 3leds blinking fast with blue color, and not able to get the pfsense.

rdatla

Hello Team,
I have encountered a problem recently with SG-3100 device. I observed the device blinks all 3 leds with blue color in fast mode. I tried to reset it using the backside reset pin, but no luck. When I try to connect from console cable with putty, after initial text displaying, there is a continuous ......(dots) going on forever.

Please help me to resolve the issue.

Thanks,
Ram.

Have you tried booting it while connected to the console? What gets output before it stops with the dots ("...")?

If all else fails, you can contact TAC at https://go.netgate.com to get the firmware and reinstall. Requesting firmware is free, but does require you to sign up on that site to submit the request.

At least one other user reported this same type of issue in a thread on another sub-forum here (under General Questions, I believe).

The cause turned out to be a zero-length config.xml file on the box. How that zero-length file got that way was an unresolved issue, but the fix was to delete any zero-length config.xml files in this path: /cf/conf. To do that, enter single-user mode when the prompt appears while the SG-3100 is booting. You will need to be connected using the serial console cable to do this.

Here is the link to that other thread: https://forum.netgate.com/topic/162104/pfsense-2-5-stacks-at-boot-with-dots.

@bmeeks Thank you. It really helped me to resolve the issue. I just deleted the 0 size config file. It booted normally after that.

Thank you very much.

Glad that got you going. The zero-length file becomes a problem if it has the most recent date/timestamp of the config.xml files in the folder. Upon booting, the system will load the most recent config.xml file it finds in that path. If that happens to be the corrupted zero-length one, then you get the stacking dots.

It probably is fixed by https://redmine.pfsense.org/issues/11748 which means it would be OK on the latest version of pfSense Plus on the 3100. Is it running 21.05 or something older?
