What is this Port for?

Looking at the machine from the front, it is on the back, on left hand side, where the USB cable comes out, opposite side from the power cord.

The sticker seems like it should be on the other side, where the power cord attaches. I think it has nothing to do with this port.

Motor wires for an indexer?

That's it. Thanks. So the label does make sense there. Something I don't need for a long while lol.
