brandwidth Posted July 23, 2019 Share Posted July 23, 2019 My ISY will boot only in safe mode - if the PLM is connected it won't let me telnet in. The Rx light on the ISY flashes when there's Insteon traffic - no lights are lit other than the power LED. What should I do next to troubleshoot this? I have a very recent backup if necessary Link to comment
brandwidth Posted July 23, 2019 Author Share Posted July 23, 2019 I've tried: a) using a different (known good) network cable b) resetting the PLM No success with either :/ Link to comment
lilyoyo1 Posted July 23, 2019 Share Posted July 23, 2019 Did you plug the plm into port A and power it up prior to powering up the ISY? Link to comment

lilyoyo1 Posted July 23, 2019 Share Posted July 23, 2019 Try factory resetting the plm and plugging it into a different outlet. If that doesn't work then it's bad. Link to comment
brandwidth Posted July 23, 2019 Author Share Posted July 23, 2019 Yes, it looks like a dead PLM. I've ordered another one. Thanks @lilyoyo for confirming my bad news! If only Insteon's hardware were as reliable as UDI's hardware. I don't post much, because I have few questions, but I am always amazed by Michel's low latency, high accuracy responses on this forum. UDI's customer support is amazing, and the products are just as good. Link to comment
Brian H Posted July 23, 2019 Share Posted July 23, 2019 If it is less than two years old. Call Smarthome Customer Support and get a warranty exchange. Make sure you follow the proper procedure to replace the PLM. https://wiki.universal-devices.com/index.php?title=ISY-99i/ISY-26_INSTEON:File_Menu#Restore_Modem_.28PLM.29 There is a long thread here on the PLM failures and how some of us have rebuilt ours with good capacitors. https://forum.universal-devices.com/topic/13866-repair-of-2413s-plm-when-the-power-supply-fails/ When you get your replacement. If you would post the Date Code and Hardware Revision number on the back. It would be nice to know. I have seen a few recent reports of V2.5 hardware being received. Link to comment
brandwidth Posted July 24, 2019 Author Share Posted July 24, 2019 I got a V2.4 from Amazon - dated 1017. Disturbingly, the ISY doesn't want to talk to it either. Any thoughts on what to try next? Link to comment
lilyoyo1 Posted July 24, 2019 Share Posted July 24, 2019 What was your step by step process Link to comment
brandwidth Posted July 24, 2019 Author Share Posted July 24, 2019 I followed the instructions from the wiki post referenced above by Brian H. Since I have a recent backup, I decided to factory reset the ISY and restore from the backup. That seemed to do the trick - it's working fine with the 'old' PLM now. Annoying, as it'd be nice to have had the logs to see if it's something that might happen to other people. Anyway, I'm back in business...living in a non-smart home for 24 hours wasn't much fun Link to comment
