Cisco Catalyst C9500‑NM‑BLANK – Blank Network Module for Catalyst 9500 Series (NM‑BLANK)

The Cisco Catalyst C9500‑NM‑BLANK is a blank network module cover designed for the Cisco Catalyst 9500 Series switches. When network uplink ports are not required or no active network module is installed, this blank module is inserted into the empty module slot. It ensures proper airflow and thermal performance within the switch chassis, protects internal circuitry from dust and debris, and maintains a clean, professional look.

Unlike standard network modules, the blank cover does not include any ports, optics, or active components — its sole purpose is maintenance of system integrity and cooling efficiency, especially in environments where all uplink slots are unused. It is compatible with Catalyst 9500 models that support optional network modules or blank covers.

Key Features:

• Designed specifically for Cisco Catalyst 9500 Series switch chassis

• Fills unused uplink module slots to maintain proper airflow

• Protects internal components from dust and debris ingress

• No active ports or connectivity — purely a cover and airflow management part

• Easy tool‑less installation and removal
