Appl. No.:

11/361297

Inventors:

Craig Donald Dubrule - Cary NC, US
Phong Hoang Ho - Cary NC, US

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

H05K 7/20
G06F 1/20

US Classification:

361692, 3616795, 36167951

Abstract:

A chassis panel for a computerized device includes ventilation elements that visually obscure electronic components disposed within an associated chassis and that minimize airflow resistance. Each ventilation element includes a first angled ventilation portion having openings that provides limited visual access to the electronic components disposed within the chassis. Each ventilation element also includes a second angled ventilation portion having openings that provide no visual access to the electronic components disposed within the chassis. As such, the ventilation elements visually obscure the electronic components disposed within the chassis without the need for additional materials such as screens, mesh, or foam. Also, the openings of the first and second ventilation portions provide the chassis panel with a relatively large free area ratio, such as between about 42% and 48% or greater depending on hole pitch values and opening sizes. As such, the ventilation elements help to maximize air flow through the chassis to allow cooling of the electronic components disposed therein.

International Classification:

H01R 2500

US Classification:

439638, 439 59

Abstract:

A card-receiving connector includes a legacy connector part and an additional connector part that facilitates plugging in cards having improved functionality while also allowing legacy cards to be plugged in.

Assignee:

Cisco Technology, Inc. - San Jose CA

International Classification:

G08C 19/22
H04L 25/49

Abstract:

According to one aspect, a method includes obtaining a first signal from a host at an air mover system, the air mover system including an air mover and a tachometer, the tachometer having an associated tachometer signal. The method also includes determining whether the first signal is a request for information associated with the air mover, and providing the information from the air mover system to the host on the associated tachometer signal when it is determined that the first signal is the request for information associated with the air mover.
