My ISY-99 stopped responding to commands last week. Finally got some time today to dig into it and noticed that the ERR light is flashing (but not the MEM light). I searched the forum and found that this means the filesystem is bad, likely a problem with the SD card.
The only troubleshooting idea I saw is to try to telnet to the ISY. Unfortunately, the device no longer shows up on my router's DHCP client table, so I have no address to telnet to.
Also, I saw that a power outage could cause this behavior (problem with shorting the PLM power supply), and we did have an outage last week. If this was the cause, does this mean the unit is toast? And is the PLM destroyed too?
Is there anything else I can try in order to connect to and update the ISY, or is it beyond hope?
Thanks in advance for any help,
Paul
