Hey there wondering if anyone can help?
I have 6x 1747-L551 processors and about a month ago I connected to them all by serial port and null modem cable and got comms. I configured the processors to be network controlled giving them an ip address and then stored them for a month or so.
Now when I go to turn them back on I get the boot sequence of:
Fault light flash
All lights flash
Fault light flash
No lights displayed
then after around 2 minutes I get the ENET light flash a few times and then go out. I find when I plug my processors into an active network card I can get the ENET light to stay on but cannot see it in BOOTP and the lights aren't flashing. (I can't remember the IP's anyway).
I have tried communicating with the units via the same serial cable as before and still can't get anywhere so now I can't control the processors at all. I have also tried pulling the battery and shorting the cap to reset the unit's memory but this doesn't seem to help either.
Any suggestions?
