An installation instruction conveying device. In one embodiment, the installation instruction conveying device is comprised of a first surface having instructions visibly disposed thereon for installing a component. The installation instruction conveying device is further comprised of a means for adhering said installation instruction conveying device to a component installation location. The installation instruction conveying device prevents the installation of the component at the component installation location unless the installation instruction conveying device is removed from said component installation location.

A device for deterring displacement of a cable is effectuated in an embodiment of the invention by an enclosure that envelopes the cable and an affixing mechanism that couples the enclosure to the cable, where the cable is oriented in an assembly such that the enclosure contacts a feature internal to the assembly and deters displacement of the cable.

An electro-magnetically shielded metallic enclosure is provided with a novel hinge structure. The enclosure has a plurality of side panels and at least one access door hinged to one of the side panels by a plurality of shielded hinges. Each such hinge has three principal elements: a metallic tab, an elongated slot for receiving and supporting the metallic tab, and a raised metal arch bridging the central portion of the elongated slot. The metallic tab is integrally formed on one edge of the access door and is designed to slide into an elongated slot located in an adjacent side panel to provide support for pivoting the metallic tab and the connected door in a hinged relationship. To prevent EMR from otherwise leaking through the elongated slot, a raised metal arch is provided on the interior of the enclosure bridging the central portion of the slot. The arch is spaced apart from the inner surface of the side panel to permit the free end of the metallic tab to freely rotate when the access door is swung open and closed.

An electro-magnetically shielded fan grill for use in venting air to a metallic cabinet. The fan grill has a multitude of arcuately-shaped trapezoidal vent apertures formed in one of the side panels of the cabinet. The vent apertures are optimally arranged in a plurality of concentric circular rows. Each aperture is substantially the same size and shape as every other aperture in the same row. Each aperture and each row of apertures is spaced apart so that the minimum distance between each aperture is substantially the same for all apertures in all rows. The size of each aperture is designed so that the longest chord of any arc segment is made less than .lambda./10 which .lambda. is the wavelength of the highest frequency signal to be contained within the enclosure. At least a single row of aperture vents near the outside perimeter of the grill is inclined outwardly from the plane of the side panel at an angle .alpha..sub.o so as to displace the plane of those apertures in the center section of the grill. The central portion of the fan grill is thus extended outwardly, so that a fan housing can be connected directly to the interior face of the side panel, without excessive air turbulence. In an alternate embodiment, all of the apertures are bowed outwardly so that a fan housing can be connected directly to the interior face of the side panel, without excessive air turbulence.
