Can someone help with these? The pics are front and back of the same board. They are approx. 18” in length and 12” wide (rough guess I didn’t measure). There are gold pins in every single slot front and back and also gold pins in the places where there is no black plastic around it. I was looking at maybe backplane but these don’t really look exactly like that. Any help is greatly appreciated.

These are a great example of Backplane.

The board is at least backplane, but with this style of backplane it could possibly go higher. I had a few that were similar, and they got upgraded to high grade telecom, but that was a few years ago, and things may have changed.

If shipping, quote as backplane. Or if driving in person, set it on top of your bin, so it will get noticed.

Remove the terminator in the one slot. You could break off the plastic for at least peripheral, or throw it as is into the gold pin connector bin.

Thank You! I will put them as backplane but put on top. I plan on driving them in since I’m only about 1 1/2 hours away.
