AI summary

Devices, systems, and methods for managing server chassis are disclosed. The server chassis may be managed thermally by controlling a flow of gas through an opening in the server chassis. The server chassis may be managed for security by controlling physical access to various portions of the server chassis, and, for example, to a portion of the server chassis proximate to an opening in the server chassis through which gas flows for thermal management purposes. The server chassis may also be managed electromagnetically by controlling a flow of electromagnetic radiation into and out of the server chassis and, for example, through an opening in the server chassis through which gas flows for thermal management purposes. The server chassis may also be managed structurally by physically reinforcing various portions of the server chassis.
