Abstract

An electronic equipment enclosure includes a frame structure and a customizable side air dam kit. The frame structure includes a front frame, a rear frame, front-to-back frame members connecting corners of the front and rear frames together, reinforced bracket structures located near ends of the cross members, and extruded horizontal mounting rails parallel to, but inward from, the front-to-back frame members. The ends of the horizontal mounting rails are connected to the reinforced bracket structures. Panels are installed in longitudinal slots in the front-to-back frame members and horizontal mounting rails, each of which is extruded. The customizable side air dam kit includes a framework of horizontal and vertical frame pieces, adapted to connect to the frame structure, and a customizable air dam panel supported by the framework. A plurality of the frame pieces are provided to an installer for use in constructing the framework to fit the specific frame structure.

6. The electronic equipment enclosure structure of claim 2, wherein the reinforced bracket assembly further includes a cover disposed around the brace structure.

7. The electronic equipment enclosure structure of claim 1, wherein the front-to-back horizontal mounting rail is an upper front-to-back horizontal mounting rail.

8. The electronic equipment enclosure structure of claim 1, wherein the front-to-back horizontal mounting rail is a lower front-to-back horizontal mounting rail.

9. The electronic equipment enclosure structure of claim 1, wherein the reinforced bracket assembly includes a brace structure, having at least an L-shaped cross-section that includes a first vertical portion that is interconnected to the end of the front-to-back horizontal mounting rail and a second vertical portion, angled relative to the first vertical portion, that braces the first vertical portion against the corresponding front or rear side-to-side cross member.

10. The electronic equipment enclosure structure of claim 9, wherein the brace structure of each reinforced bracket assembly has a U-shaped cross-section that includes the first vertical portion, the second vertical portion, and a third vertical portion, wherein the third vertical portion is angled relative to the first vertical portion and braces the first vertical portion against the side-to-side cross member.

11. The electronic equipment enclosure structure of claim 10, wherein the second and third vertical portions of the brace structure each include a respective tab that extends through the side-to-side cross member.

12. The electronic equipment enclosure structure of claim 11, wherein the reinforced bracket assembly further includes a reinforcement plate, wherein the bulk of the brace structure is disposed on the opposite side of the side-to-side cross member from the reinforcement plate, and wherein the tabs of the brace structure extend through the side-to-side cross member and reside in slots in the reinforcement plate.

13. A frame structure for an electronic equipment enclosure, comprising:

(a) a front frame, including a first pair of vertical frame members, a first upper side-to-side cross member, and a first lower side-to-side cross member;
