“When should an older UPS be replaced with a new one?” is a question that virtually all data center owners will have to answer. The answer is not always self-evident and depends on several factors.

Read this paper, which provides data center owners and managers a simple framework for answering the question in the context of their own circumstances and requirements.

Three options are explained and compared:

• Buy new – Should the UPS be replaced with a new one?
• Upgrade – Can it be revitalized in some way to extend the life and performance for several more years?
• Do nothing – Or is it better to do nothing beyond the most basic maintenance and just let it, ”run-to-fail”?
