Any pointers to what to do? SSH will not let me enter using ‘root’ as user/password.
Ping works and the AP is visible and gives me an IP address but same deal when browsing though that way.
OpenWRT, the OS used by the RAK7249, uses Lua to run the web interface known as Luci. If that’s borked, along with not being able to ssh, you may benefit from updating the firmware for the gateway.
But it may be ‘parasitic’ power rather than the full current it needs. Either way, I doubt it’s going to get fixed whilst up the pole, as if it needs a POE injector or the card reflashing, it will need to be to hand.
I drained the backup battery (20+h) and then powered it up using the POE injector. It’s now alive. Is the injector needed you think or was the hard reset the only thing needed?
I’m not sure I really understand this - if you are powering the gateway via Power Over Ethernet, then a POE Injector is needed if your network switch/router doesn’t provide POE to get power up to the gateway.
I have a POE network, meaning it get 48V negotiated with the switch. But it seems like the RAK7249 isn’t fully compliment with the POE spec if I need to use the injector.
Let me draw a simple schematic to show the difference:
###Not working (it seems)###
Internet - Router (AC in, POE out) - Switch (POE in, POE out) - RAK7249 (POE in)
To address the last question; I couldn’t browse the login page. Read my first post. Only that text was displayed.
Now it’s working and I have only turned the unit off by draining the backup battery.
But my final question is: did the “restarted unit” fix the problem or the “POE injector vs POE switch”? Not sure if it’s a question to you in particular or if it’s RAK engineers who’s to blame for it
Excuse me??? You drained the battery, effectively doing a hard reset by your own account then posted the login page. How unreasonable was I to expect you to try a login after a reboot?
I’d not really expect a sequence of POE in & out to work - at each step they take the 48V down to working voltages and then potentially have to take it up to 48V again. Even if it’s passed straight through, I’d still not expect such a daisy chain to work.
With such a power setup, I’d go for “all bets are off”, I’d go for my brownout idea and perhaps the culprit lives at the underneath that pole
