Rack mounts are hardware devices designed to hold and organize electronic equipment in a standardized frame called a rack. These racks are commonly used in data centers, server rooms, and audio-visual setups, allowing for efficient use of space and easy access to equipment. Typically measured in U (rack units), rack mounts can accommodate various devices such as servers, network switches, and audio equipment. They help ensure proper ventilation and cable management, making it easier to maintain and upgrade technology as needed.
