The FAN‑T1 is a Cisco fan module specifically engineered for the Catalyst 3650 Series switches, providing essential cooling support to maintain optimal operating temperatures and system reliability. Designed to integrate seamlessly into the modular chassis architecture of the Catalyst 3650, this fan module helps ensure consistent airflow and efficient heat dissipation across the device’s internal components. By replacing or supplementing existing fans, the FAN‑T1 enhances the overall thermal management of the switch, contributing to sustained performance, reduced risk of overheating, and extended hardware lifespan.
