An electronics chassis is provided that utilizes multiple fan units, each of which may incorporate multiple fans, to improve airflow through an internal enclosure of the chassis. Various combinations of multiple fan units are utilized to increase airflow and provide redundancy in the event of the failure of one or more fans. In one arrangement, combinations of horizontally mounted and vertically mounted fans are utilized to improve airflow. In further arrangements, multiple access openings are provided into the enclosure such that an individual fan unit or an individual fan may be accessed for servicing purposes without altering or discontinuing the operation of other fans or fan units.

What is claimed is: 1. An electronics chassis system comprising: an enclosure having four vertical sidewalls, a top surface and a bottom surface, wherein an interior of the enclosure includes an upper plenum, a lower plenum and a section disposed between the plenums for receiving a plurality of electronics boards; a first access opening to the upper plenum; a first fan unit, wherein the first fan unit is selectively removable through the first access opening and wherein the first fan unit is aligned with an air outlet through a first of the vertical sidewalls to move air in a direction substantially normal to the first vertical sidewall; a second access opening to the upper plenum; and a second fan unit, wherein the second fan unit is selectively removable through the second access opening and wherein the second fan unit is disposed substantially normal to the vertical sidewalls to move air in a direction substantially parallel to the vertical sidewalls. 2. The system of claim 1, wherein the first access opening is disposed through a first vertical sidewall. 3. The system of claim 2, wherein the second access opening is disposed through a second, vertical sidewall. 4. The system of claim 3, wherein the first and second vertical sidewalls are nonadjacent. 5. The system of claim 1, wherein the air outlet forms at least a portion of the first access opening. 6. The system of claim 1, wherein the first fan unit and the second fan unit both draw air into the upper plenum and the first fan unit exhausts air from the plenum through the air outlet. 7. The system of claim 1, wherein at least one of the first and second fan units comprises a fan assembly including a plurality of fans. 8. The system of claim 7, wherein each individual fan of the fan assembly is removable for exchange without terminating operation of remaining fans of the fan assembly. 9. The system of claim 7, wherein operation of each fan in the fan assembly is individually controllable. 10. The system of claim 9, wherein the plurality of fans are disposed in series. 11. An electronics chassis system comprising: an enclosure having four vertical sidewalls, a top surface and a bottom surface, wherein an interior of the enclosure includes an upper plenum, a lower plenum and a section disposed between the plenums for receiving a plurality of electronics boards; a first access opening to the upper plenum, wherein the first access opening is disposed through a first vertical sidewall; a first fan unit, wherein the first fan unit is selectively removable through the first access opening and wherein the first fan unit is aligned with an air outlet through a first of the vertical sidewalls; a second access opening to the upper plenum; and a second fan unit, wherein the second fan unit is selectively removable through the second access opening and wherein the second fan unit is aligned with an air outlet through a second of the vertical sidewalls. 12. The system of claim 11, wherein the first fan unit comprises a fan assembly including a plurality of fans and wherein an operating speed of at least a number of the fans in the fan assembly is individually controllable. 13. The system of claim 12, wherein each individual fan of the fan assembly is removable for exchange without terminating operation of remaining fans of the fan assembly. 14. The system of claim 12, wherein operation of each fan in the fan assembly is individually controllable based on cooling requirements within the enclosure. 15. The system of claim 11, wherein the second fan unit comprises a fan assembly including a plurality of fans and wherein an operating speed of at least a number of the fans in the fan assembly is individually controllable. 16. The system of claim 15, wherein each individual fan of the fan assembly is removable for exchange without terminating operation of remaining fans of the fan assembly. 17. The system of claim 15, wherein operation of each fan in the fan assembly is individually controllable based on cooling requirements within the enclosure. 18. The system of claim 11, wherein the first and second vertical sidewalls are nonadjacent. 19. The system of claim 11, wherein the air outlets form at least portions of the first and second, access openings. 20. An electronics chassis system comprising: a chassis for holding a plurality of electronics boards disposed in parallel, wherein the chassis comprises four vertical sidewalls, a top surface and a bottom surface an interior of the chassis includes an upper plenum, a lower plenum, and a section disposed between the plenums for receiving the electronics boards; a first access opening to the upper plenum; a first fan unit, wherein the first fan unit is selectively removable through the first access opening and wherein the first fan unit is aligned with an air outlet through a first of the vertical sidewalls to move air in a direction substantially normal to the first vertical sidewall; a second access opening to the upper plenum; and a second fan unit, wherein the second fan unit is selectively removable through the second access opening and wherein the second fan unit is disposed substantially normal to the vertical sidewalls to move air in a direction substantially parallel to the vertical sidewalls; wherein the second fan unit comprises a fan assembly including a plurality of fans and wherein an operating speed of at least a number of the fans in the fan assembly is individually controllable. 21. The system of claim 20, wherein the first fan unit is vertically aligned relative to the air outlet, wherein the first fan unit is operative to draw air horizontally through the upper plenum. 22. The system of claim 20, wherein the second fan unit is operative to displace air vertically through spaces between the plurality of electronics boards. 23. The system of claim 22, wherein the second fan unit is disposed in the upper plenum above the plurality of electronics boards, wherein the second fan unit draws air through the spaces. 24. The system of claim 20, wherein each individual fan of the fan assembly is removable for exchange without terminating operation of remaining fans of the fan assembly. 25. The system of claim 20, wherein operation of each fan in the fan assembly is individually controllable based on cooling requirements within the chassis. 26. The system of claim 16, wherein the first fan unit comprises a first plurality of fans, wherein each of the first and second fan units is removable without terminating operation of the other of the first and second fan units. 27. The system of claim 20, wherein the first fan unit comprises a fan assembly including a plurality of fans, the operating speed of at least a number of the fans in the fan assembly being individually controllable.
