System and design of cost effective chassis design for networking products
View Patent ↗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.
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;
a first region being open to the first side of the chassis, and configured to receive one or more first networking modules oriented with a first orientation;
a second region being open to the second side of the chassis and configured to receive one or more fan trays and one or more second networking modules, the one or more second 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 connectors for coupling the one or more first networking modules to power being distributed on the power distribution board;
wherein:
the power distribution board only partially separates the first region from the second region; 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 second networking modules near the mid-plane of the chassis using one or more connectors.
3. The chassis of claim 1 wherein at least one of the first networking modules, the one or more fan trays, or the one or more second 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 one or more second networking modules include one or more route processing modules.
6. The chassis of claim 1 wherein the first region is further configured to receive a third networking module oriented with the first orientation, the third networking module being coupled to each of the second networking modules near the mid-plane of the chassis using one or more connectors.
7. The chassis of claim 6 wherein the third networking module includes an uplink module.
8. The chassis of claim 6 wherein the third networking module adds stability to the frame.
9. The chassis of claim 1 , further comprising a third region configured to receive one or more power supply modules for supplying power to the chassis and the power distribution board.
10. The chassis of claim 9 wherein the third region is adjacent to the first region and is open to the first side.
11. The chassis of claim 1 , further comprising an auxiliary power shelf configured to receive one or more auxiliary power modules.
12. The chassis of claim 1 wherein the one or more fan trays are configured to extend beyond the second side of the chassis.
13. The chassis of claim 1 , further comprising one or more additional fans located near the mid-plane of the chassis.
14. The chassis of claim 1 , further comprising one or more air baffles.
15. The chassis of claim 1 wherein at least one of the one or more first networking modules includes an electromagnetic interference gasket.
16. The chassis of claim 1 wherein at least one of the one or more first networking modules includes an alignment element.
17. 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.
18. The chassis of claim 1 wherein at least one of the first networking modules or the one or more fan trays adds stability to the frame.
19. The chassis of claim 1 wherein the one or more fan trays each includes one or more fans.
20. An information handling system comprising:
one or more electrical equipment chassis, each chassis comprising:
a frame open to a first side of the chassis and a second side of the chassis opposite the first side;
a first region being open to the first side of the chassis, and configured to receive one or more first networking modules oriented with a first orientation;
a second region being open to the second side of the chassis and configured to receive one or more fan trays and one or more second networking modules, the one or more second 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 connectors for coupling the one or more first networking modules to power being distributed on the power distribution board;
wherein:
the power distribution board only partially separates the first region from the second region; and
the chassis is sufficiently open to permit air flow from the first side to the second side.
