Modular card cage accessories
Various types of electronic devices may be mounted in a chassis in order to facilitate interfacing with the devices, containing the devices, provide cooling systems which may remove heat from the electronic devices, etc. Delivering adequate cooling air flow to each electronic device in a chassis may be an important issue for the proper functioning, lifetime, or other characteristics of electronic devices contained in a chassis. Some electronic devices may be particularly challenging to cool due to various design characteristics. Other electronic devices may have other requirements that are not well served by existing chassis designs. For example, some electronic devices may benefit from additional electrical and/or thermal connections. Embodiments presented herein describe a novel design for a modular card cage accessory that may be configured to modify air flow and/or to meet particular requirements of an electronic device in a chassis, among various possibilities.
1. A modular card cage accessory, comprising:
a mounting feature for installation in a first slot of a card cage of a chassis;
an integrated card guide for installation of an associated electronic module in the first slot, wherein the modular card cage accessory provides a first electrical connection for the associated electronic module via a backplane of the chassis; and
a component to provide a second electrical connection for the associated electronic module to a second electronic module in a second slot of the card cage of the chassis, wherein the second electrical connection is a direct connection and does not use the backplane of the chassis.
2. The modular card cage accessory of claim 1 , wherein the modular card cage accessory further comprises electromagnetic shielding for the associated electronic module.
3. The modular card cage accessory of claim 1 , wherein the modular card cage accessory has a first shape prior to installation of the associated electronic module and a second shape after the installation of the associated electronic module, wherein the second shape is different than the first shape.
4. The modular card cage accessory of claim 1 , wherein the second electrical connection includes a data connection with a higher data rate than the first electrical connection.
5. The modular card cage accessory of claim 1 , wherein the associated electronic module is a nonstandard module, wherein the integrated card guide allows for installation of the nonstandard module.
6. The modular card cage accessory of claim 1 , wherein the modular card cage accessory further includes a sensor, wherein the second electrical connection includes a connection of the sensor to the second electronic module.
7. The modular card cage accessory of claim 1 , wherein the modular card cage accessory is further configured to direct air flow to cool the associated electronic module.
8. The modular card cage accessory of claim 1 , wherein the second electrical connection includes a data connection with a lower latency than the first electrical connection.
9. The modular card cage accessory of claim 1 , wherein the second electrical connection supports signal requirements of the associated electronic module in excess of those supported by the first electrical connection.
10. A system, comprising:
a chassis comprising a card cage, the card cage comprising:
at least a first slot and a second slot; and
a backplane; and
a modular card cage accessory comprising:
a mounting feature for installation in the first slot of the card cage of the chassis;
an integrated card guide for installation of an associated electronic module in the first slot, wherein the modular card cage accessory provides a first electrical connection for the associated electronic module via the backplane of the chassis; and
a component to provide a second electrical connection for the associated electronic module to a second electronic module in the second slot of the card cage of the chassis, wherein the second electrical connection is a direct connection and does not use the backplane of the chassis.
11. The system of claim 10 , wherein the modular card cage accessory further comprises electromagnetic shielding for the associated electronic module.
12. The system of claim 10 , wherein the modular card cage accessory has a first shape prior to installation of the associated electronic module and a second shape after the installation of the associated electronic module, wherein the second shape is different than the first shape.
13. The system of claim 10 , wherein the second electrical connection includes a data connection with a higher data rate than the first electrical connection.
14. The system of claim 10 , wherein the associated electronic module is a nonstandard module, wherein the integrated card guide allows for installation of the nonstandard module.
15. The system of claim 10 , wherein the modular card cage accessory further includes a sensor, wherein the second electrical connection includes a connection of the sensor to the second electronic module.
16. The system of claim 10 , wherein the modular card cage accessory is further configured to direct air flow to cool the associated electronic module.
17. The system of claim 10 , wherein the second electrical connection includes a data connection with a lower latency than the first electrical connection.
18. The system of claim 10 , wherein the second electrical connection supports signal requirements of the associated electronic module in excess of those supported by the first electrical connection.
19. A method, comprising:
installing a modular card cage accessory in a first slot of a card cage of a chassis using a mounting feature of the modular card cage accessory, wherein the modular card cage accessory comprises:
an integrated card guide for installation of an associated electronic module in the first slot, wherein the modular card cage accessory provides a first electrical connection for the associated electronic module via a backplane of the chassis; and
a component to provide a second electrical connection for the associated electronic module to a second electronic module in a second slot of the card cage of the chassis, wherein the second electrical connection is a direct connection and does not use the backplane of the chassis.
20. The method of claim 19 , wherein the modular card cage accessory is further configured to direct air flow to cool the associated electronic module.
