Supermicro MCP-260-00042-0N I/O shield for X9 socket R server MB with gasket server accessory

Purpose-built I/O shield

The Supermicro MCP-260-00042-0N is a standard I/O shield designed for X9 socket R server motherboards. It provides the rear-panel cut-outs required by that specific platform. The integrated gasket helps seal the chassis opening against dust and airflow leaks. System builders and IT technicians fitting or repairing X9-based servers use this part to complete the enclosure.

Replaces missing or damaged shields

This accessory replaces an absent or bent original shield on compatible Supermicro X9 socket R boards. The jump is worth it when the rear aperture is open, letting unfiltered air enter or allowing EMI to escape. It also solves fitment issues caused by warped metal that prevents clean port alignment. No other motherboard generation or form factor is supported by this part number.

Fits X9 socket R server builds

The shield mounts directly into the standard rectangular cut-out of a server chassis built for X9 socket R motherboards. It requires no screws, clips or tools beyond the case’s own retention mechanism. Once seated, it frames every rear I/O port exactly as the board layout demands. Builders who need a different port pattern or a shield for another socket must source a different part number.
