C9500-ACC-KIT-23I Cisco Network Device Accessories Kit 23

The Cisco C3KX‑FAN‑23CFM is a replacement fan module engineered for Cisco Catalyst 3560‑X and 3750‑X Series switches to help maintain proper cooling and reliable operation of these enterprise network devices. Rated at 23 CFM (cubic feet per minute) airflow with front‑to‑back air movement, it actively removes heat from inside the switch chassis to prevent overheating during heavy use. This fan is hot‑swappable, meaning it can be replaced without shutting down the switch, supporting continued network uptime during maintenance. By delivering efficient, low‑noise cooling that aligns with the switch’s thermal design, the C3KX‑FAN‑23CFM helps protect internal components, extend hardware longevity, and support stable performance in rack‑mounted network environments
