TJF1960 Posted December 21, 2010 Posted December 21, 2010 I have had an ongoing problem since I purchased the ISY from SH about 2 years ago that I haven’t been able to rectify. The ISY was an 99i but have since upgraded it to 99ir pro with the addition of the ir module and online pro upgrade and is running v2.8.9. The plm is 2412s v.92 If I remove power from the plm (ISY’s plm) for more than 8-10 seconds then reconnect power there is a good chance that the ISY will freeze up during the boot process (seems like just before it would normally start to query devices). This happens probably 5 out of 10 times. Usually, but not always, if I cycle the power for less than 5 seconds the ISY will boot up properly. There has been no indication of any rhyme or reason to when or how it will freeze up, or why. The freeze up has been worse in the last 6 months than it was at first. When the ISY freezes up the Pwr, TX and RX LED’s are all lit solid. The wiki describes the condition of RX lit solid as a problem with the plm or cable, but it doesn’t describe the TX LED on solid or both RX and TX on solid. I have replaced the plm with my other new spare, no difference. I have also replaced the cable twice with no difference either. I also have added the wall power supply to feed the ISY power but that didn’t help either. The error log doesn't indicate a problem either. At first it seemed it would only occur when unplugging the plm, not when rebooting from the admin console but a couple of days ago it did freeze when I rebooted from the console. It hasn’t been a huge deal but my fear is one day when I am out of town and there is a power interruption……. Any suggestions? Thanks, Tim
Michel Kohanim Posted December 21, 2010 Posted December 21, 2010 Hi Tim, Quick questions: 1. Your PLM firmware version 2. Do you use a power supply? 3. ISY's firmware version 4. Do you have EZRain devices? If so, have you tried removing them from ISY and see if you can reproduce the issue? Thanks and with kind regards, Michel
TJF1960 Posted December 21, 2010 Author Posted December 21, 2010 Hi Michel, 1) PLM 2412S v3.3 (v.92) 2) Have had malfunction with and without the external power supply (doesn't seem to matter). 3) ISY 99ir pro v2.8.9 4) Yes, 1 EZFlora device with new updates from SHN. No, I haven't tried removing it (didn't know it could cause this problem). Do I have to remove from the ISY (a lot of work to reinstall) or can I simply unplug it? If it matters I have 1 EZIO6 and 1 EZIO2x4 as well. Thanks, Tim
Michel Kohanim Posted December 21, 2010 Posted December 21, 2010 Hi Tim, Thanks. This is the issue: With EZRain, ISY tries to initialize it so that it can communicate with ISY. Thsi is done at reboot and if ISY cannot communicate with it, it seems that it's hung. But, if you wait about 2 minutes (all the retries) it would come back on. So, instead of removing EZRain, try to reproduce the problem and wait between 2 to 3 minutes. If it works, then we know the problem is one of the EZRains. With kind regards, Michel
TJF1960 Posted December 21, 2010 Author Posted December 21, 2010 Right on, that will be a lot easier to try. THANK YOU! By the way, when you say "EZRains" you mean EZRain or EZFlora right, and not all of the EZxxx products. Thanks, Tim
Michel Kohanim Posted December 22, 2010 Posted December 22, 2010 Hi Tim, Yes, EZRain and EZFlora only. We do not have to initialize EZIO devices. With kind regards, Michel
TJF1960 Posted December 22, 2010 Author Posted December 22, 2010 Well, no such luck. I waited for an hour and the ISY still had the Pwr, TX and RX LED's stuck on. Was unable to enter the admin console at all. Once I rebooted again all was fine. Next Suggestion? Thanks, Tim
Michel Kohanim Posted December 22, 2010 Posted December 22, 2010 Hi Tim, If you have the same problem with multiple PLMs, and if you have an extra PLM, then the best thing to do would be to send one to us so that we can test it. Currently, we are using 2413s exclusively and cannot reproduce this problem. With kind regards, Michel
Sub-Routine Posted December 22, 2010 Posted December 22, 2010 Hi Tim, Since Michel thinks it may be an issue with querying the EZRain/Flora you might try to set it to Disabled. Then the ISY won't try to Query it. Your Programs and Scenes will still control the device. Rand
TJF1960 Posted December 22, 2010 Author Posted December 22, 2010 Hi Michel, Ok, I will send my spare plm. Hi Rand, Tried your suggestion, still locked up. Thanks to both of you. Tim
TJF1960 Posted January 1, 2011 Author Posted January 1, 2011 Looks like an EZIO6 I recently was having problems with may have been the cause of, or at least contributed to this problem. Since removing the ez I have not had one single lock up after rebooting. Pretty strange right. I cant explain it but am happy with the outcome. Thanks Tim
Michel Kohanim Posted January 2, 2011 Posted January 2, 2011 Hi Tim, Thanks so very much for the update. I still would be very interested to know what in EZIO is causing the hang. If you are not sending your EZIO for repair, may I ask to have it for a couple of days? With kind regards, Michel
TJF1960 Posted January 2, 2011 Author Posted January 2, 2011 Hi Michel, Yes, no problem. I am just really glad that I can powercycle the ISY/PLM and walk away knowing full well that it will reboot fully now! I am going to send it in for repair once you are finished with it, but not in a huge hurry so take all the time you need. Thanks, Tim
