I ran a Ubiquiti Edge Router Lite as my home firewall for a couple of years. The box had a nice GUI with CLI option, and had no problem keeping up with my > 100Mbps Internet connection. The box died after a lengthy power failure that drained the large UPS buffering electrons in my basement equipment rack.
I’m not sure what happened to the ERLite-3, but it’s as dead as the bird in the Python parrot sketch. The firewalls appears to boot. The lights come on, etc. However, the box passes no traffic and responds to no ARP requests. I can get no serial console output from it. I even tried a full factory reset, to no effect.
Until its early death, the little firewall had a trouble-free two year run. For $99 spent according to my Amazon order history, I don’t feel too badly about the loss.
Before throwing it in the bin, I decided to open it up and take a look at the mainboard. Here’s a notated picture for you. Enjoy.
- My thanks to @williamhulley for correcting the first version of this diagram.
- @Brownout suggests that the firewall might have bricked due to a problem with the USB key. “Usually it’s the USB key, there’s a procedure on the forums to reinstall EdgeOS on a new one.”
I exercised my google-fu based on Brownout’s input, and came up with this link, “EdgeMax rescue kit (now you can reinstall EdgeOS from scratch).” Seems promising if you want to try to rescue your ERLite!
