C9606-FAN Cisco Catalyst 9600 Fan Tray

C9606-FAN Overview

The Cisco C9606‑FAN is a dedicated fan tray assembly designed for the Cisco Catalyst 9600 Series (C9606R) modular switch chassis, and it plays a critical role in the system’s thermal management. Rather than being an active networking component, this field‑replaceable module houses multiple independently controlled cooling fans that maintain proper airflow across the internal supervisor engines, line cards, and power supplies to keep the switch operating within safe temperature limits. The fan tray supports side‑to‑side airflow, can be accessed from the front or rear for flexible serviceability, and uses advanced sensors to adjust fan speeds dynamically if one fails without significantly degrading cooling performance, helping protect the hardware and ensure reliable long‑term operation in enterprise campus and data‑center environments.
