a rear section having at least one second card wherein the at least one second card is configured to receive ambient air through a face thereof; a middle section disposed between the front section and the rear section; and a channel structure within the middle section configured to vent air out of the apparatus. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the channel structure is configured to vent air from a lower portion of the middle section to an upper portion of the middle section. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the channel structure is configured to pull air out of the front section and the rear section. ### Claim 4 (depends on 1) The apparatus of claim 1, wherein the front section includes a first plurality of cards oriented horizontally and the rear section includes a second plurality of cards oriented vertically. ### Claim 5 (canceled) ### Claim 6 (depends on 5) The apparatus of claim 5, wherein different cards of the at least one first card vent different volumes of air therethrough. ### Claim 7 (depends on 1) The apparatus of claim 1, comprising a midplane in the middle section, wherein the at least one first card is connected to the at least one second card through the midplane. ### Claim 8 (depends on 1) The apparatus of claim 1, wherein the at least one first card is not connected to the at least one second card through the middle section. ### Claim 9 A chassis apparatus, comprising: a first portion of the chassis apparatus configured to draw in air in a first direction; a second portion of the chassis apparatus configured to draw in air in a second direction substantially opposite to the first direction; and a third portion of the chassis apparatus configured to receive the air from the first direction and the second direction and channel the air in a third direction substantially perpendicular to the first direction and the second direction; and a curved channel structure disposed in the middle portion, the curved channel structure having perforations to receive air from the front portion and the rear portion. ### Claim 10 (depends on 9) The chassis apparatus of claim 9, wherein the curved channel structure is configured to receive the air and exhaust it in the third direction. ### Claim 11 (depends on 9) The chassis apparatus of claim 9, wherein the first portion is configured to hold a first plurality of cards. ### Claim 12 (depends on 11) The chassis apparatus of claim 11, wherein the first plurality of cards each have first vents configured to receive ambient air to cool fronts of the first plurality of cards. ### Claim 13 (depends on 9) The chassis apparatus of claim 9, wherein the second portion is configured to hold a second plurality of cards. ### Claim 14 (depends on 13) The chassis apparatus of claim 13, wherein the second plurality of cards each have second vents configured to receive ambient air to cool fronts of the plurality of cards. ### Claim 15 (depends on 13) The chassis apparatus of claim 13, wherein the second plurality of cards have optical transceivers disposed on respective faces thereof and each optical transceiver receives substantially a same amount of air. ### Claim 16 (depends on 9) The chassis apparatus of claim 9, wherein the third portion includes a channel structure having a plurality of perforations configured to receive air from the first direction and the second direction and direct it upwards. ### Claim 17 (depends on 9) The chassis apparatus of claim 9, comprising a wire mesh disposed in the third portion to connect electrical components in the first portion to electrical components in the second portion. ### Claim 18 (depends on 1) The apparatus of claim 1, wherein the channel structure includes perforations to correspond to the front section and the rear section respectively. ### Claim 19 (depends on 9) The chassis apparatus of claim 9, wherein the first portion and the second portion are disposed at the same vertical level. ### Claim 20 (depends on 9) The chassis apparatus of claim 9, wherein the perforations are elongated around a portion of the curved channel structure. ### Claim 21 (depends on 9) The chassis apparatus of claim 9, wherein the perforations vary in size from one end of the curved channel structure to another.
