The N3K‑C3048‑FAN is a replacement fan module designed for the Cisco Nexus 3048 series. It delivers forward airflow, directing hot air out of the port side of the chassis to maintain optimal internal temperature and performance. This module is engineered to fit the Nexus 3048’s fan slot configuration, ensuring seamless integration with existing hardware. By exhausting heat from the port side, it supports efficient cooling and helps preserve the reliability and longevity of the network device. The unit is a standard component for maintaining airflow balance and thermal management in Cisco Nexus 3048 deployments.
