Part 03X3835 is a 3.5-inch hot-swap drive carrier used in many Lenovo rack-mount and tower servers. It allows quick insertion or removal of SAS or SATA hard drives while preserving front-to-back airflow. A spring-loaded blue release handle enables tool-less service, and four mounting screws are included.
