The system also comprises a plurality of switch-fabric cards arranged along a second orientation orthogonal to the first orientation, the switch-fabric cards operable to route data between the one or more port cards based on one or more rules. The system further comprises a plurality of bridge cards coupling the one or more port cards to the one or more switch-fabric cards, the bridge cards arranged physically between the port cards and switch-fabric cards. ## Claims ### Claim 1 A system, comprising: a plurality of port cards arranged along a first orientation, the port cards operable to receive data from one or more nodes on a network; a plurality of switch-fabric cards arranged along a second orientation orthogonal to the first orientation, the switch-fabric cards operable to route data between the one or more port cards based on one or more rules; and a plurality of bridge cards coupling the one or more port cards to the one or more switch-fabric cards, the bridge cards arranged along the second orientation and physically between the port cards and switch-fabric cards, each bridge card coplanar with at least one of the plurality of switch-fabric cards. ### Claim 2 (depends on 1) The system of claim 1, wherein the number of bridge cards is equal to the number of switch-fabric cards. ### Claim 3 (depends on 1) The system of claim 1, wherein the number of bridge cards is twice the number of switch-fabric cards. ### Claim 4 (depends on 1) The system of claim 1, wherein the port cards are arranged at a front end of an enclosure and the switch-fabric cards are arranged at a rear end of the enclosure. ### Claim 5 (depends on 1) The system of claim 1, wherein the switch-fabric cards arranged at a front end of an enclosure and the port cards are arranged at a rear end of the enclosure. ### Claim 6 (depends on 1) The system of claim 1, wherein the port cards, the switch-fabric cards, and the bridge cards are arranged to allow air to flow parallel to each of the port cards, the switch-fabric cards, and the bridge cards from a front end of an enclosure to a rear end of the enclosure. ### Claim 7 (depends on 1) The system of claim 1, further comprising one or more supervisor cards coupled to the bridge cards and arranged along the first orientation, the supervisor cards operable to monitor at least one of the port cards, bridge cards, and switch-fabric cards. ### Claim 8 (depends on 1) The system of claim 1, further comprising one or more power modules coupled to the bridge cards and arranged along the first orientation, the power modules operable to provide power to the port cards, bridge cards, and switch-fabric cards. ### Claim 9 A system, comprising: a plurality of port cards arranged along a first orientation, the port cards operable to receive data from one or more nodes on a network; a plurality of switch-fabric cards arranged along a second orientation orthogonal to the first orientation, the switch-fabric cards operable to route data between the one or more port cards based on one or more rules; and a plurality of bridge cards coupling the one or more port cards to the one or more switch-fabric cards, the bridge cards arranged along the second orientation and having a first end and a second end, each bridge card coplanar with at least one of the plurality of switch-fabric cards; wherein a first portion of the port cards and a first portion of the switch-fabric cards couple to the bridge cards at the first end. ### Claim 10 (depends on 9) The system of claim 9, wherein a second portion of the switch-fabric cards couple to the bridge cards at the second end. ### Claim 11 (depends on 9) The system of claim 9, wherein a second portion of the port cards couple to the bridge cards at the second end. ### Claim 12 (depends on 9) The system of claim 9, wherein the number of bridge cards is equal to the number of switch-fabric cards. ### Claim 13 (depends on 9) The system of claim 9, wherein the number of bridge cards is twice the number of switch-fabric cards. ### Claim 14 (depends on 9) The system of claim 9, wherein the port cards and switch-fabric cards are arranged at a front end of an enclosure. ### Claim 15 (depends on 14) The system of claim 14, wherein the bridge cards are arranged at a rear end of the enclosure. ### Claim 16 (depends on 9) The system of claim 9, wherein the port cards, the switch-fabric cards, and the bridge cards are arranged to allow air to flow parallel to each of the port cards, the switch-fabric cards, and the bridge cards from a front end of an enclosure to a rear end of the enclosure. ### Claim 17 (depends on 9) The system of claim 9, further comprising one or more supervisor cards coupled to the bridge cards and arranged along the first orientation, the supervisor cards operable to monitor at least one of the port cards, bridge cards, and switch-fabric cards. ### Claim 18 (depends on 9) The system of claim 9, further comprising one or more power modules coupled to the bridge cards and arranged along the first orientation, the power modules operable to provide power to the port cards, bridge cards, and switch-fabric cards.
