So here is the pic of the cabinet id jumper location on an S32 or S23. I was thinking if yours is a first generation blade you probably have the small 3.2 mpu not the 3.2.2 or 3.5.x and I can't remember if the back plane in those have this jumper or not. The error though is synonymous with the jumper missing in the newer equipment so it would seem it would be the general issue. The cabinet serial number is registered to the nvram of the back plane. If the jumper isn't the issue maybe something is preventing the serial from clearing with a ram clear as it looks like the error is duplicated 15ish times with different serial numbers. Just a though, hope it helps.
**Error reading second baseboard id would be serial number to back plane assignment issue.
