Abstract: An electronic equipment rack is disclosed in which multiple electronic equipment components can be vertically mounted and vertically stacked within the rack. A component of electronic equipment, such as a standard rackable 1U-3U server chassis, having a configuration with its typical depth plane or dimension (z-axis) being both greater than or equal to its width plane or dimension (x-axis) and greater than its height plane or dimension (y-axis), is mounted in a vertical orientation on the rack, wherein the component is oriented and mounted on the rack such that the component's typical z-axis is substantially parallel to and in the same plane as the rack's x-axis and the component's typical x-axis is substantially parallel to and in the same plane as the rack's y-axis. Preferably, the component is further so oriented and mounted on the rack such that a user's desired surface (e.g., top or bottom) of the component's typical z-axis plane is readily accessible by the user.
