Connectivity scheme and cooling scheme for a large rack system

摘要

A rack system may include a first plurality of line cards, where a particular one of the first plurality of line cards receives or sends packets via ports; a plurality of fabric cards, where a particular one of the plurality of fabric cards includes a switching fabric; a second plurality of line cards, where a particular one of the second plurality of line cards receives or sends packets via ports; a first backplane that connects the first plurality of line cards to the plurality of fabric cards; and a second backplane that connects the second plurality of line cards to the plurality of fabric cards.

主权项

1. A network device comprising:
a first plurality of cards; a second plurality of cards; a fabric card,
the fabric card including a baffle that separates air flow across the fabric card into a first air flow and a second air flow,
the baffle directing:
the first air flow across an upper portion of the fabric card and toward the first plurality of cards, andthe second air flow across a lower portion of the fabric card and toward the second plurality of cards; and two or more of:
a first backplane that connects the first plurality of cards to the fabric card,a second backplane that connects the fabric card to the second plurality of cards,a third backplane that connects the second plurality of cards to another fabric card of the network device, ora fourth backplane that connects the other fabric card to a third plurality of cards of the network device.
