Abstract

An electrical equipment chassis includes a frame open to a first side and an opposite second side and a power board located near a mid-plane of the chassis coupling power supply modules to first networking modules and a second networking module. A first region open to the first side can receive first power supply modules. A second region open to the first side is adjacent to the first region and can receive the first networking modules and the second networking module oriented with a first orientation. A third region open to the second side can receive fan trays with fans and third networking modules. The third networking modules are oriented orthogonal to the first orientation. The power board at least partially separates the first and third regions and only partially separates the second and third regions. The chassis permits air flow from the first side to the second side.

Claims (45)

1. An electrical equipment chassis, the chassis comprising:

a frame open to a first side of the chassis and a second side of the chassis opposite the first side, the frame separating the chassis into a first region, a second region, and a third region;

the first region being open to the first side of the chassis and configured to receive one or more first power supply modules for supplying power to the chassis;

the second region being open to the first side of the chassis, adjacent to the first region, and configured to receive one or more first networking modules and a second networking module, the one or more first networking modules and the second networking module being oriented with a first orientation;

the third region being open to the second side of the chassis and configured to receive one or more fan trays and one or more third networking modules, the one or more third networking modules being oriented with a second orientation orthogonal to the first orientation; and

a power distribution board located near a mid-plane of the chassis and including one or more power module connectors for coupling the one or more first power supply modules to the power distribution board and one or more first power connectors for coupling the one or more first networking modules and the second networking module to the power distribution board;

wherein:

the one or more fan trays each includes one or more fans;

the power distribution board at least partially separates the first region from the third region and only partially separates the second region from the third region;

at least one of the second networking module, the one or more fan trays, or the one or more third networking modules adds stability to the frame; and

the chassis is sufficiently open to permit air flow from the first side to the second side.

2. The chassis of claim 1 wherein:

each of the one or more first networking modules is coupled to each of the third networking modules near the mid-plane of the chassis using one or more first connectors; and

the second networking module is coupled to each of the third networking modules near the mid-plane of the chassis using one or more second connectors.

3. The chassis of claim 1 wherein at least one of the second networking module, the one or more fan trays, or the one or more third networking modules are configured to be affixed to the frame.

4. The chassis of claim 1 wherein the one or more first networking modules includes one or more line cards or one or more service modules.

5. The chassis of claim 1 wherein the second networking module includes an uplink module.

6. The chassis of claim 1 wherein the one or more third networking modules include one or more route processing modules.

7. The chassis of claim 1 , and further comprising an auxiliary power shelf configured to receive one or more auxiliary power modules.

8. The chassis of claim 1 , and further comprising one or more interconnect boards configured to:

couple the power distribution board to the one or more third networking modules; and

couple at least a first one of the one or more third networking modules to a second one of the one or more third networking modules.

9. The chassis of claim 1 wherein the one or more fan trays each includes a first row of fans positioned to the outside of a second row of fans.

10. The chassis of claim 1 wherein the one or more fan trays are configured to extend beyond the second side of the chassis.

11. The chassis of claim 1 , and further including one or more additional fans located near the mid-plane of the chassis.

12. The chassis of claim 1 wherein the frame includes at least one selected from a group consisting of power supply guides in the first region and module alignment guides in the second region.

13. The chassis of claim 1 , and further comprising one or more air baffles.

14. The chassis of claim 1 wherein at least one of the one or more first networking modules includes an electromagnetic interference gasket.

15. The chassis of claim 1 wherein at least one of the one or more first networking modules includes an alignment element.

16. The chassis of claim 1 wherein at least one of the one or more first networking modules includes an array of ventilation holes open to the first side of the chassis.

17. The chassis of claim 1 wherein the second networking module includes an electromagnetic interference gasket.

18. The chassis of claim 1 wherein the second networking module includes an alignment element.

19. The chassis of claim 1 wherein the second networking module includes an array of ventilation holes open to the first side of the chassis.

20. An information handling system comprising:

one or more electrical equipment chassis, each chassis including:

a frame open to a first side of the chassis and a second side of the chassis opposite the first side, the frame separating the chassis into a first region, a second region, and a third region;

the first region being open to the first side of the chassis and configured to receive one or more first power supply modules for supplying power to the chassis;

the second region being open to the first side of the chassis, adjacent to the first region, and configured to receive one or more first networking modules and a second networking module, the one or more first networking modules and the second networking module being oriented with a first orientation;

the third region being open to the second side of the chassis and configured to receive one or more fan trays and one or more third networking modules, the one or more third networking modules being oriented with a second orientation orthogonal to the first orientation; and

a power distribution board located near a mid-plane of the chassis and including one or more power module connectors for coupling the one or more first power supply modules to the power distribution board and one or more first power connectors for coupling the one or more first networking modules and the second networking module to the power distribution board;

wherein:

the one or more fan trays each includes one or more fans;

the power distribution board at least partially separates the first region from the third region and only partially separates the second region from the third region;

at least one of the second networking module, the one or more fan trays, or the one or more third networking modules adds stability to the frame; and

the chassis is sufficiently open to permit air flow from the first side to the second side.
