## Long description

The Lenovo ThinkSystem 450W Titanium HS power supply unit is a redundant server power module engineered for enterprise environments.

How to use
Install the power supply into a compatible Lenovo ThinkSystem hot-swap bay following the server manufacturer’s insertion guidance. For redundancy, configure power modules according to the server’s redundancy policy and monitor status through system management tools.
