Choosing the Right UPS for your Lenovo ThinkServer System

This guide provides an overview of uninterruptible power supply (UPS) technologies and the information necessary to select a UPS that is compatible with a Lenovo ThinkServer system. Although the information that is presented in this guide is universal, the recommendations are for ThinkServer products only and do not apply to Lenovo System x servers because these servers use different power supplies that might not have the same requirements as those described in this paper.

At Lenovo Press, we bring together experts to produce technical publications around topics of importance to you, which provides information and best practices for the use of Lenovo products and solutions to solve IT challenges.
