The crossbar includes a frame, a keystone portion of the frame forming a keystone air duct, and a riser guide extending from the frame. The keystone portion is operable to direct air flow through the keystone air duct towards a heat sink and/or a CPU. The riser guide is operable to align a riser to be plugged into a motherboard installed in the sled. The frame is operable to be a structural component that is substantially coupled to the sled chassis. ## Claims ### Claim 1 A crossbar operable to be removably installed in a sled for a modular server and/or information handling system, the crossbar comprising: a frame; a keystone portion of the frame forming a keystone air duct, the keystone portion operable to direct air flow through the keystone air duct towards a heat sink and/or a central processing unit (CPU); and a riser guide extending from the frame, the riser guide operable to align a riser to be plugged into a board installed in the sled. ### Claim 2 (depends on 1) The crossbar of claim 1, further comprising an air dam adjacent to the keystone air duct, the air dam operable to prevent air from passing therethrough to assist in directing the air flow through the keystone air duct. ### Claim 3 (depends on 2) The crossbar of claim 2, wherein the air dam is received in a dam cavity formed from the frame. ### Claim 4 (depends on 1) The crossbar of claim 1, wherein the keystone air duct includes a cavity formed from the frame. ### Claim 5 (depends on 1) The crossbar of claim 1, wherein the frame includes two lateral sides, wherein each of the two lateral sides includes at least one pin and a fastener, the at least one pin and the fastener operable to couple the frame to the sled. ### Claim 6 (depends on 5) The crossbar of claim 5, wherein the at least one pin is operable to be received in a corresponding pin opening in the sled, and the fastener is operable to be received in a corresponding plunger opening in the sled. ### Claim 7 (depends on 5) The crossbar of claim 5, wherein the fastener is spring loaded. ### Claim 8 (depends on 1) The crossbar of claim 1, wherein the riser guide includes a floor and at least one guide side which forms a receiving portion operable to receive a guiding portion of the riser. ### Claim 9 (depends on 8) The crossbar of claim 8, wherein the floor includes a coupling component operable to couple with the riser via a riser coupler. ### Claim 10 (depends on 1) The crossbar of claim 1, wherein the riser guide is operable to be coupled with the riser by threaded engagement. ### Claim 11 A modular server and/or information handling system comprising: a sled including a chassis and a lid operable to close the chassis, the chassis operable to receive a board, a central processing unit (CPU), a heat sink, and a riser; and a crossbar operable to be removably installed in the sled, the crossbar including: a frame; a keystone portion of the frame forming a keystone air duct, the keystone portion operable to direct air flow through the keystone air duct towards the heat sink and/or the CPU; and a riser guide extending from the frame, the riser guide operable to align the riser to be plugged into the board installed in the sled. ### Claim 12 (depends on 11) The modular server and/or information handling system of claim 11, wherein the crossbar further includes an air dam adjacent to the keystone air duct, the air dam operable to prevent air from passing therethrough to assist in directing the air flow through the keystone air duct and the heat sink. ### Claim 13 (depends on 12) The modular server and/or information handling system of claim 12, wherein the air dam is operable to abut against the lid so that air flow across the air dam between the air dam and the lid is prevented. ### Claim 14 (depends on 11) The modular server and/or information handling system of claim 11, wherein the keystone air duct includes a cavity formed from the frame. ### Claim 15 (depends on 11) The modular server and/or information handling system of claim 11, wherein the frame includes two lateral sides, wherein each of the two lateral sides includes at least one pin and a fastener, the at least one pin and the fastener operable to couple the frame to the sled, wherein the at least one pin is operable to be received in a corresponding pin opening formed in the chassis of the sled, and the fastener is operable to be received in a corresponding plunger opening formed in the chassis of the sled. ### Claim 16 (depends on 11) The modular server and/or information handling system of claim 11, wherein the riser includes a full-length riser or a half-length riser such that the sled is operable to accommodate either the full-length riser or the half-length riser interchangeably. ### Claim 17 (depends on 11) The modular server and/or information handling system of claim 11, wherein the riser guide includes a floor and at least one guide side which forms a receiving portion operable to receive a guiding portion of the riser. ### Claim 18 (depends on 11) The modular server and/or information handling system of claim 11, wherein the riser guide is operable to be coupled with the riser by threaded engagement. ### Claim 19 (depends on 11) The modular server and/or information handling system of claim 11, wherein the sled further includes one or more baffles operable to prevent air from passing therethrough to assist in directing the air flow through the keystone air duct and the heat sink. ### Claim 20 (depends on 19) The modular server and/or information handling system of claim 19, wherein at least one of the one or more baffles and the crossbar together forms a cable management channel operable to receive cables disposed in the sled.
