I had a 532A on top of a Grain Elevator (257 Steps up) That needed up graded. I was on a older OS.
So I waited till after 9pm to upgrade because there are many business off of this Sector. So I upgraded to 3.15 and this radio never came back up.
So I needed to roll, got up top and my ups was beeping (weird). The first thing I did was disconnect the serial cable for the ups and rebooted the radio, it came up just fine. I then took and did a soft reboot (system – reboot) with the UPS cable plugged back in and rebooted fine. Now I took and did a hard reboot (pull power cord) and the ups started beeping again and the radio never came back up. Tried a few more times still same thing.
I then took and downgraded to 3.14 and all is working as it should.
I don’t have a supout, didn’t think of it at the time.
