Abstract:
1. A device, comprising: a first array, of a first plurality of line cards, where the first array is oriented in a first direction in a chassis of the device; a second array, of a second plurality of line cards, where the second plurality of line cards is different than the first plurality of lines cards and the second array is oriented in a second direction in the chassis, the second direction being different than the first direction; a midplane connecting one or more first line card of the first plurality of line cards with one or more second line card of the second plurality of line cards; and a fan tray assembly, including a plurality of fans, oriented in the chassis in the second direction, to: provide a first portion of an airflow, having a third direction, provide, from the first portion of the airflow, a second portion of the airflow, having the second direction that is orthogonal to the third direction, to remove heat from the second array, provide, from the second portion of the airflow, a third portion of the airflow having a fourth direction that is orthogonal to the second direction, and the fourth direction is opposite to the third direction, and provide, from the third portion of the airflow, a fourth portion of the airflow having a fifth direction that is orthogonal to the fourth direction, to remove heat from the first array.
