C3850-NM-BLANK Overview

The Cisco C3850‑NM‑BLANK is a blank network module accessory designed for the Cisco Catalyst 3850 Series switches. Instead of providing uplink ports like the other optional network modules, this part simply fills an unused network module slot on the switch when uplinks are not needed, helping protect the internal chassis from dust, debris, and accidental contact while maintaining the proper airflow required for cooling and efficient operation. By installing the blank module in place of an uplink module, network administrators can keep the switch’s physical appearance neat and maintain the thermal characteristics specified by Cisco for reliable performance and longevity of the device.
