UBNT PoE Factory Default Reset...

[darren]

I haven't tried this or even seen this on one of our older Digital-Loggers 24VDC PoE rebooters, but I happened to notice DL claims they have a way to factory default UBNT gear over the Ethernet cable from their reboot switch.

Today we had a UBNT AP require several "factory default resets" before we had it squared away. Fortunately it was in a relatively easily acessable location. This would be a nice feature to add to the Netonix switches.

From their website:

"Bottom line is that to press the reset button on the M-series hardware remotely all you need to do is to put +15 to +24V on the center tap of the ethernet transformer at the remote end, with respect to the power supply ground"

Won't putting the port into 24VH mode and then back into 24v mode achieve this?

NO - If you turn on 24VH to a standard airMAX radio it will fry the radio and the Ethernet port which this type of damage is not covered under UBNT or Netonix warranty.

24VH WILL FRY LEGACY 10/100 airMAX RADIOS

Wow - no need to shout - the explanation would have been sufficient.

LOL, not shouting, sorry if you took it that way, just making sure people notice it because I seem to keep saying it over and over again yet people still manage to fry ports in switches by doing just that.

I did try this on port 2 (25VH) on the WS-6-MINI with a PowerBeam AC-500. It did reset to default and it's still working fine.
Won't recommend it though....

A PBE-5AC has a gig port so pins 1,2&3,6 are all to centre tap on the ethernet transformer. 100 meg kit is different.

I could see the use for a remote reset. We have a few solar sites that when winter rolls in it's a really long way in to do anything. We mount extra hardware that isn't powered just in case though :)

If you have a router on site or even upstream there is simply no need to monkey with any NAT in the switch to reprogram, use a router for what it's designed for. I frequently have my not so savvy installers mount gear on towers that's still defaulted and then I deal with programing it from my office. Honestly much simpler than explaining it over the phone.

The catch is that if you are routing and then you reset the radio to factory, you have to have a route to that 192.168.1.0/24 subnet to reprogram it. You could destination NAT it, or do a tunnel of some sort, but there is something that needs to be done to access that 192.

When our installers install a replacement Rocket M5 on a tower we simply add the ip address 192.168.1.1 255.255.255.0 secondary to the virtual interface in the tower router connected to the radio.

Next we SSH into the Rocket from the router and use the Linux command to set the radio IP/MASK/Gateway.

Now we can login to the web UI as normal from our workstation and set it up.

Lastly we remove the temporary IP address - no ip address 192.168.1.20 255.255.255.0 secondary

Done

Chris, I'm not prepared to train people on SSH login and openwrt commands :p

I've been setting up an nginx reverse proxy and adding a NAT entry on each site-router to 192.168.1.20 so users can hit a landing page and just click on the site and they will get whichever device is at the factory default. Much less training that way. It works, I just got side tracked so I only have a couple sites in there to test.
