Abstract: A rack system for housing electronic and/or electrical equipment is provided comprising a rectangular base frame, a rectangular top frame, and four elongated vertical support members each extending along a longitudinal axis between and joined to two associated corners of the rectangular base frame and the rectangular top frame. The rectangular base frame, rectangular top frame, and the four elongated vertical support members may be constructed from members having the same substantially A-frame cross-section. Each support member may be constructed from an elongated sheet material extending along a longitudinal axis by bending the sheet material about an axis parallel to the longitudinal axis of the sheet material to form at least three elongated sections, where a first section and a second section are adjacent and substantially perpendicular to each other and a third section extends between approximately mid-point of the first section and approximately mid-point of the second section.

Abstract: A technique for climate control of, for example, base station circuitry within an enclosure involves placing base station circuitry within the enclosure and controlling the climate therein. A system according to this technique includes an enclosure suitable for use outside in a wide range of extreme weather conditions. A controller may, for example, control a fan tray with a heater to pull ambient air through a filtration unit, through the fan tray where the air is heated, and through cold start recirculation dampers.

Abstract: A rack system for electronic and/or electrical equipment including a frame, a front door mounted to the front of the frame, a back door or panel, two side panels mounted to the back and two sides of the frame, and a top panel mounted to the top of the frame. The doors can be single doors or dual doors. The frame includes a rectangular base frame constructed by four horizontal edge members, and a top frame having the same structure as the base frame, and four vertical members each extending between two associate corners of the base frame and the top frame, and joining the base frame and top frame together. The horizontal members and vertical members are contoured with step-like structures, so that the rack has a high stiffness and strength. The door includes a hinge and a latch attached to two vertical members. The panels are provided with tabs and latches for securing the panels to the frame.
