Cisco Removable Faceplate for SM Slot Blank Cover

The Cisco SM-S-BLANK is a removable faceplate that covers an unused SM expansion slot on compatible Cisco Integrated Services Routers. By sealing the opening, it keeps dust, debris, and accidental contact away from the internal circuitry, which helps maintain airflow and prolongs the life of the router.

This faceplate fits naturally on Cisco ISR models 2901, 2911, 2921, 2951, 3925, and 3945. Network administrators who manage branch offices, classrooms, or small data centers often leave slots empty while planning for future growth. Installing this blank cover delivers a clean look in the rack and removes the worry of contaminants entering the chassis during day-to-day operation.

Setup is quick. The faceplate aligns with the router housing, and the fastening points match the factory hardware, allowing technicians to snap it into place without special tools. Once installed, the finish blends with the router so the system retains a uniform, professional appearance.

Whether you are staging new equipment, performing upgrades, or simply tidying a long-running deployment, the Cisco SM-S-BLANK offers a straightforward way to protect your investment and keep the workspace organized.
