Power Supplies - Lenovo ThinkServer TD350 Product Manual

Power supplies

The TD350 supports up to two redundant hot-swap AC power supplies. Power supplies are Energy Star 2.0
compliant and 80 PLUS certified. The server ships with country-specific power cords.
The power supplies that are available for the TD350 are highly efficient with Energy Star / 80 Plus Platinum and
Titanium supplies. Several power supply options are available and they can be selected to match the workload
and configuration of the server for even greater efficiencies. All power supplies that are used in the TD350 are
common across the ThinkServer next-generation server portfolio, which simplifies management across large
installations. Power supplies are auto-sensing and feature a line-cord retention mechanism to prevent
unintended disconnects.
