The Brocade 60-0207117-01 100-652-031 is a hot-swappable fan module manufactured for the Brocade Silkworm 4100 switch. It is designed in a modular form factor and supports high-speed cooling for fibre channel systems operating at up to 4 Gbps transmission speeds.

This module is compatible with the 1U rack-mounted Brocade Silkworm 4100, which supports up to 32 ports. It operates on DC power supplied by the host chassis and is installed via a rear-side mounting slot within the switch enclosure. Its primary function is maintaining airflow efficiency across critical internal components under continuous operation conditions unless user-initiated replacement or maintenance occurs.
