Embodiment Construction

[0013] Various embodiments of the network switch devices described herein have multiple line cards mounted orthogonally to and electrically coupled to the switch cards and address packaging, connection, maintenance and replacement of components and challenges in a rack mount environment. Various problems with deployment or configuration. One version has a midplane solution, while the other has an orthogonal direct connector solution without a midplane.

[0014] figure 1 is a block diagram of a switch card 102 (or fabric card) with switch chips 104 fanning out to multiple line cards 106 for a network switch device. In this embodiment, instead of having multiple switch cards 102 and / or multiple switch chips 104, the network switch device has a single non-redundant switch card 102 with a single (or multiple) switch chips 104, the The switch chip has all the switches of a network switch. The switches within switch chip 104 may be referred to as switching paths or routing paths....

Abstract

A network device is provided. The apparatus includes a housing and a switch card mounted within the housing and having one or more connectors. A plurality of line cards are oriented parallel to each other and orthogonal to the switch card and assembled to the one or more connectors of the switch card. The switch card has a chip with a plurality of switches or routing paths, and the switch card and the chip are coupled to the plurality of line cards through the one or more connectors.

Description

Background technique [0001] Network switch devices typically have multiple line cards, and each line card can have multiple lines. Multiple switch cards, each containing multiple switching circuits for connecting line cards, are common in such devices. The connector pin density and area for the connectors on the card (eg, printed circuit board) are the limiting factors for the packing density of network devices. Obstruction of cooling airflow is also a design consideration. Typically, a midplane solution is applied to connect multiple switch cards to multiple line cards. However, midplanes impede airflow and can increase signal reflections and cost in the system. Inconvenient maintenance and access to line cards and switch cards in conventional network switches. For example, one problematic factor is the amount of insertion or removal force required to remove a switch card connected to multiple line cards, maintain or replace a switch card. With an insertion / removal force...
