A module recess is adjacent a first end of the electronic module and a module roller is adjacent a second end. A sealing retainer is coupled between the chassis and each electronic module, and includes a cooling gas passageway aligned with a chassis cooling gas passageway and a module cooling gas passageway. The sealing retainer includes a rigid retainer body having a retainer recess adjacent a first end to receive the module roller when the electronic module is in an inserted position. A retainer roller is received in a module recess and a compressible retainer body is between the rigid retainer body and the chassis. ## Claims ### Claim 1 An electronic assembly comprising: a chassis having a plurality of electronic module mounting positions, each electronic module mounting position having a chassis cooling gas passageway; a respective electronic module received in each electronic module mounting position and having a module cooling gas passageway, the electronic module having a module recess adjacent a first end thereof and a module roller adjacent a second end thereof opposite the first end; and a respective sealing retainer coupled between the chassis and each electronic module, the sealing retainer having a cooling gas passageway therethrough aligned with the chassis cooling gas passageway and the module cooling gas passageway, the sealing retainer comprising a rigid retainer body having a top surface and opposing lower surface, and a retainer recess formed on the top surface adjacent a first end thereof to receive the module roller when the electronic module is in an inserted position, a roller cutout formed within the top surface of the rigid retainer body adjacent a second end thereof opposite the first end, a retainer roller carried within the roller cutout and configured such that a top section of the retainer roller extends above the top surface, said retainer roller received in the module recess when the electronic module is in the inserted position, a compressible retainer body between the lower surface of the rigid retainer body and the chassis; and a sealing gasket carried by the rigid retainer body on the top surface. ### Claim 2 (depends on 1) The electronic assembly of claim 1 wherein the module roller comprises a module shaft and module tubular roller rotatably carried thereby. ### Claim 3 (depends on 1) The electronic assembly of claim 1 wherein the retainer roller comprises a retainer shaft and retainer tubular roller rotatably carried thereby. ### Claim 4 (depends on 1) The electronic assembly of claim 1 wherein the chassis cooling gas passageway comprises a chassis cooling gas inlet passageway. ### Claim 5 (depends on 1) The electronic assembly of claim 1 wherein the chassis cooling gas passageway comprises a chassis cooling gas outlet passageway. ### Claim 6 (depends on 1) The electronic assembly of claim 1 comprising at least one cooling gas manifold coupled to the chassis. ### Claim 7 (depends on 6) The electronic assembly of claim 6 wherein the at least one cooling gas manifold comprises an inlet cooling gas manifold and an outlet cooling gas manifold. ### Claim 8 (depends on 1) The electronic assembly of claim 1 wherein each electronic module comprises a circuit board having a cooling gas path associated therewith, and an electrical connector carried by a first end of the circuit board. ### Claim 9 A sealing retainer to be coupled between a chassis and an electronic module, the chassis having a plurality of electronic module mounting positions and each electronic module mounting position having a chassis cooling gas passageway, the electronic module having a module cooling gas passageway, a module recess adjacent a first end thereof, and a module roller adjacent a second end thereof opposite the first end, the sealing retainer comprising: a rigid retainer body having a top surface and opposing lower surface, and a retainer recess formed on the top surface adjacent a first end thereof to receive the module roller when the electronic module is in an inserted position, the rigid retainer body having a first cooling gas passageway to be aligned with the module cooling gas passageway; a roller cutout formed within the top surface of the rigid retainer body adjacent a second end thereof opposite the first end, a retainer roller carried within the roller cutout and configured such that a top section of the retainer roller extends above the top surface, said retainer roller received in the module recess when the electronic module is in the inserted position; a compressible retainer body between the lower surface of the rigid retainer body and the chassis and having a second cooling gas passageway to be aligned with the chassis cooling gas passageway; and a sealing gasket carried by the rigid retainer body on a side thereof opposite the compressible retainer body. ### Claim 10 (depends on 9) The sealing retainer of claim 9 wherein the module roller comprises a module shaft and module tubular roller rotatably carried thereby. ### Claim 11 (depends on 9) The sealing retainer of claim 9 wherein the retainer roller comprises a retainer shaft and retainer tubular roller rotatably carried thereby. ### Claim 12 (depends on 9) The sealing retainer of claim 9 wherein the electronic module comprises a circuit board having a cooling gas path associated therewith, and an electrical connector carried by a first end of the circuit board. ### Claim 13 A method of mounting an electronic module in an electronic module mounting position of a chassis, the electronic module mounting position having a chassis cooling gas passageway, and the electronic module having a module cooling gas passageway, a module recess adjacent a first end thereof, and a module roller adjacent a second end thereof opposite the first end, the method comprising: coupling a sealing retainer between the chassis and the electronic module, the sealing retainer comprising a rigid retainer body having a top surface and opposing lower surface, and a retainer recess formed on the top surface adjacent a first end thereof to receive the module roller when the electronic module is in an inserted position, the rigid retainer body having a first cooling gas passageway to be aligned with the module cooling gas passageway, a roller cutout formed within the top surface of the rigid retainer body adjacent a second end thereof opposite the first end, a retainer roller carried within the roller cutout and configured such that a top section of the retainer roller extends above the top surface, said retainer roller received in the module recess when the electronic module is in the inserted position, a compressible retainer body between the lower surface of the rigid retainer body and the chassis and having a second cooling gas passageway to be aligned with the chassis cooling gas passageway;
