An Ethernet patch panel is typically a metal frame with rows of RJ45 ports on the front and punch-down or keystone terminations on the rear. They come in a range of sizes, and are typically mountable, whether that's on a wall, or on a rack to make for easier. Patch panels are used to bring cables run from individual end devices such as computers and servers to a single location where they can be patched to other equipment using patch cables. Unlike active devices that process data, a patch panel simply provides structured termination points for each Ethernet cable run, creating a clean, scalable. A patch panel is a passive hardware unit that consolidates multiple network connections in one location. Rack height is measured in rack units (U).
