ESM2 BP Primary Sensor Check Error Code 1700:0E24

Question

I'm running an older PE2450, which has been reporting a problem with the SCSI Termination A External Voltage sensor with a value of 09AA, ever since I updated the ESM firmware to a42 (Primary Backplane v1.16).   I did read that sometimes the newer firmware will report invalid values to the Server Administrator (like ridicuously high fan RPMs), so I tried downgrading to the only available older version, a40 (Primary Backplane v1.15), but that didn't resolve the problem either.   Since I don't use the external SCSI connection it doesn't cause any issues with the running of the system, but in any case I would really like to get it sorted out.   My other 2450 is fine, so are the dozens of 2850's and 2950's. Just this one box is giving me grief.   What options do I have from Dell to get it fixed?

I had tried re-seating the cables and such, but I'm not entirely sure if I'm missing a terminator or not. Since I haven't touched the H/W except for replacing the hot-pluggable SCSI drives, I'm not sure how that would happen unless someone else took it out.   So if my system has 4 hot-plug SCSI drives and a DDS-4 tape drive, as well as the CD-ROM/FDD combo drive, what cables should be connected, and which ones should be terminated.   BTW. There are 2 SCSI connectors on the backside of the backplane (facing the fans). The right one is plugged into the end connector of the SCSI cable marked 'Backplane', which goes to Channel A, and the left one is empty. The middle connector of the backplane cable is empty.   There is another SCSI cable labeled 'Peripheral' that goes from Channel B to the tape drive, but I assume that the Termination A message applies to channel A and not Channel B, and in any case that cable is terminated.   Other posts about this problem have been solved by replacing the backplane, hence the reason I asked what support I could get to do this.
