An enclosure has a perforated front door with a replaceable filter, and a perforated rear side allowing air to flow through the enclosure. The enclosure also has mounting brackets for heat generating elements, such as line cards or other rack mounted electronics. A fan draws air through the perforated front door, though the filter, and across the heat generating elements. Side brushes are disposed on a side wall near the front of the enclosure, which allow any cables attached to the heat generating elements to exit the enclosure. The front door is removable, opening up one side of the side brushes and allowing the cables to slide in the side brushes while still connected to the heat generating elements.

1. An apparatus comprising: an enclosure comprising at least one removable, perforated front door on a front side of the enclosure, and a perforated rear wall opposite the front side of the enclosure;at least one filter mounted on the perforated front door and through which air is to be drawn through;a plurality of first mounting brackets configured to mount a plurality of heat generating elements within the enclosure; anda plurality of side brush filters, each of the plurality of side brush filters including a second mounting bracket with an open side configured to allow at least one cable to slide into the side brush filter. 2. The apparatus of claim 1, wherein the perforated rear wall is a rear surface of the enclosure. 3. The apparatus of claim 2, wherein the rear surface is configured to mount at least one fan. 4. The apparatus of claim 1, wherein the heat generating elements are network line cards. 5. The apparatus of claim 4, wherein the first mounting brackets are line card cages. 6. The apparatus of claim 1, further comprising a plurality of stiff filaments mounted on the at least one front door, and configured to cover the open side of each of the side brush filters. 7. The apparatus of claim 1, wherein each of the plurality of side brush filters is configured to allow at least one cable to slide into the side brush filter, such that only a middle portion of the cable makes contact with the side brush filter, and end portions of the cable do not make contact with the side brush filter. 8. The apparatus of claim 1, wherein the enclosure filters air entering the enclosure in compliance with Network Equipment Building System (NEBS) standards. 9. The apparatus of claim 1, wherein the enclosure with the at least one front door closed is configured to form a visual barrier that ensures the plurality of heat generating elements are not visible from outside the enclosure, and such that the enclosure complies with Federal Information Processing Standards (FIPS). 10. A method comprising: removing a perforated front door of an enclosure;partially installing a heat generating element into the enclosure;attaching at least one cable to the heat generating element;sliding the at least one cable into a side brush filter mounted on the enclosure, wherein the at least one cable is slid into an open side of the side brush filter;completing the installation of the heat generating element; andre-installing the perforated front door. 11. The method of claim 10, wherein attaching at least one cable to the heat generating element comprises attaching at least one network cable to a network line card. 12. The method of claim 11, wherein completing the installation of the heat generating element comprises sliding the network line card completely within the enclosure, such that the re-installed perforated front door can be closed. 13. The method of claim 10, wherein sliding comprises sliding the at least one cable so that only a middle portion of the at least one cable makes contact with the side brush filter. 14. The method of claim 13, wherein sliding the at least one cable comprises sliding the middle portion of the at least one cable into the open side of the side brush filter, such that end portions of the at least one cable do not make contact with the side brush filter. 15. An apparatus comprising: an enclosure comprising at least one removable, perforated front door on a front side of the enclosure, and a perforated rear wall opposite the front side of the enclosure;at least one filter mounted on the perforated front door and through which air is to be drawn through;a plurality of racks configured to mount a plurality of network line cards within the enclosure; anda plurality of side brush filters mounted on a common frame;wherein each of the plurality of side brush filters is configured to allow a bundle of network cables to exit the enclosure while substantially preventing dust from entering the enclosure. 16. The apparatus of claim 15, wherein the enclosure is configured to mount a fan to draw air through the enclosure. 17. The apparatus of claim 15, wherein the perforated front door is removable from the enclosure with at least one spring-loaded hinge. 18. The apparatus of claim 15, further comprising a power supply portion that is not accessible from the at least one perforated front door. 19. The apparatus of claim 15, further comprising a plurality of securing clips corresponding to the plurality of side brush filters. 20. The apparatus of claim 1, wherein the perforated front door is removable from the enclosure with at least one spring-loaded hinge.
