NX3200 backplane signal cable errors
Hello,
I have an NX3200 array, no disks installed, but am getting a BP0 and BP1 signal cable error and was curious how concerned I should be. I inserted a disk and it showed up just fine, wondering if there are custom settings or if it needs a full load of disks before those errors go away. Not something i've seen on a poweredge server though. I will attempt to re-seat everything; the cables themselves are kind of wadded up in the tight space between backplane and fans.
Any advice is appreciated. Thanks!

Hi Mtexter,
Most likely, it is nothing to worry about, reseating the cables and clearing the system logs should resolve it. Let us know if that doesn’t fix it and we need to do more troubleshooting.

There are not any different bios settings, the OS is the main difference between the NX and poweredge.
Are they cabled like the picture?

Unfortunately that hasn't fixed the issue. I'm curious if my cabling is correct. I have the BP signal cables installed as follows:
System board port J_BP_SIG0 (near the rear backplane) is cabled to the J_BP_SIG port on the 12-bay LFF backplane.
System board port J_BP_SIG1 is connected to the rear 2-bay backplane at J_BP_SIG.
System board ports J_BP_SIG2 and J_BP_SIG3 are disconnected, all of which I believe to be correct.
Oddly, if I connect J_BP_SIG from the 12-bay backplane to J_BP_SIG3, the error about BP1 being improperly connected goes away. There must be something I'm missing. Dell's documentation on where the BP signal cables are supposed to connect for an NX3200 seems to be missing. Same for its analogue system, the R720xd.
Any further troubleshooting tips? Are there settings in BIOS specific to the NX-platform?

Yep, just like the picture (which only shows SAS connections, not BP signal cables) I might see about a replacement system board. I can't explain why moving the signal cable from port 0 to port 2 or 3 would clear the error for port 0.

Is it under warranty? You might want to have the signal cables replaced as well.

Great, glad you got it working. Let us know if you need anything else in the future.

I think I sorted it out. Just had to re-seat everything, then let the system reconfiguration run after a reboot and it seems to have knocked out the BP signal errors. Thanks all.
