You can also store data such as serial number and location with the equipment shapes and generate detailed reports based on that data. The shapes are designed to fit together precisely, and their connection points make them easy to snap into place. With Microsoft Visio, you can quickly build a rack diagram from equipment shapes that conform to industry-standard measurements. When purchasing equipment, rack diagrams can help you determine which equipment and racks to buy. A rack diagram helps make quick work of designing and documenting a rack of network equipment.
