Safe Mode even after replacing PLM

[timekiller]

Hi all, I have an ISY that has been, for the most part, rock solid for the better part of 10 years. about 5 years back my PLM died and I replaced it, I also bought a backup PLM just in case. I have everything setup the way I want and rarely log into isyadmin. Last week my automations stopped working, so I opened up the admin console and got a message that the system was in safe mode. Having seen this issue before I took a backup of the system, powered it down, and replaced the PLM. After it started back up I did File>Restore Modem and after about a half an hour (and several "unable to communicate with..." errors) it was done. I tested several devices by turning them on/off through the admin console and everything mostly worked. There was 1 device I had to manually relink, but then it was working fine. Testing automations worked as well.

Well, fast forward 2-3 days and no automations are working again. I open the admin console and I am getting the Safe Mode error again. I have tried restarting the isy several times and the error has not gone away.

I also noticed when I switch to the Programs tab I get the errors:

"Subscriber didn't reply to event: 1 [26]"

"Request Failed"

 

Is my isy shot?

There's a procedure to replace a plm... And it takes some time. On the admin console screen under fine is "replace plm"

If you're in safe mode that meas that the ISY can't communicate with the PLM.

Is the green led lit on the PLM?

Make sure the PLM cable is plugged into the correct port on the ISY and that the cable isn't defective.
