räkkikaapit

Räkkikaapit, often translated as "rack cabinets" or "server racks," are standardized enclosures used to house electronic equipment. These cabinets are designed to provide a structured and organized way to mount and manage components such as servers, network switches, routers, and other IT infrastructure. The standardization of rack cabinets is crucial for interoperability and efficient use of space in data centers, server rooms, and telecommunication facilities.

The most common width for rack cabinets is 19 inches (482.6 mm), measured from the inside edge of the mounting rails. Equipment designed to be mounted in these cabinets will have corresponding 19-inch-wide faceplates. The height of rack-mountable equipment is measured in "rack units," commonly abbreviated as U or RU. One rack unit is equal to 1.75 inches (44.45 mm). Therefore, a 42U cabinet is approximately 73.5 inches (1867 mm) tall, excluding feet or casters.

Räkkikaapit are typically constructed from steel and are available in various depths and heights to accommodate different equipment sizes and quantities. They often feature perforated doors and side panels to facilitate airflow, which is essential for cooling electronic components and preventing overheating. Many cabinets also include integrated cable management systems, power distribution units (PDUs), and shelves or rails for mounting equipment. The design of räkkikaapit is fundamental to the physical infrastructure of modern IT environments, enabling density, accessibility, and maintainability of electronic systems.
