Hi

Got an OS100 MCP1 v2.75 2x 6 Trunk 2x 8DLI Misc4
System worked fine for a day. Started resetting. Changed all cards. Stayed the same. Build complete new system with same config. Still the same. Can anybody shed some light on this. In the mean time went back to Mem3 Misc2 in same cab. No problems.I'm in South Africa.

MCP card was changed aswell?

We had this issue with one of our customers with a misc4a card - system resets were the beginning symptom of the bad powersupply issue. Check your powersupply to see if it is one of the recalled ones.

With 2.75? I guess it's possible but I am not so sure.

Have you run the system up without the expansion cab but including the new cards?

Sorry wrong config. Only 1 8 DLI. Changed the whole system including all cards. Only thing commen is the software ver. No expansion cab. Wonder if there's something wrong with the software.

If you've swapped the entire kit out(inc power supply) i'd look at the UPS or change to another power supply.

I've seen over voltages on the incomming lines cause this also.

i had one do the same thing in our own switch, after changing all the obvious found it was the 2 sli card

Remove all cards except MCP and try start PBX.

New info. You need upgrade CPLD on matherboard.
