Abstract
An electronic equipment frame comprises a base, two vertical elongate side members bolted to the base and extending upwardly therefrom for supporting electronic equipment shelves therebetween, and a top member welded to and extending between upper ends of the side members. Each side member has a relatively wide front lipped flange, providing shelf mounting holes and slots through which cables may pass, and a relatively narrow rear lipped flange, with a central portion extending therebetween. The central portion has an upstanding inverted-V portion positioned between the flanges, which define a cable duct therebetween. The frame has relatively high natural frequencies, whereby it is able to withstand earthquakes.
