Through-hole solder termination with a board guide — the guide posts align the jack during wave-solder and take the insertion shear off the signal pins when a patch cable is seated. The tab faces up, which means the locking latch on the RJ45 plug engages on the top side; confirm the enclosure cutout clears the tab height. Single-row, single-port layout keeps the PCB footprint compact for a 1U panel where every millimetre of board edge is spoken for.
