Telnet into a radio with MAC and no IP

I have an AP that just lost it’s IP. You can still see it’s MAC in the other radio’s Neighbor list, but not it’s IP, and it is still working with it’s clients.
It’s just not accessible through the IP.
I read that you can Telnet into it with it’s MAC from another radio.
In Webfig, I see a button that says Telnet MAC, but it does nothing when pushed.
Is there really a way to telnet into the radio with the MAC?
