Redundant power systems suit high-end servers

摘要

Five fault-tolerant power systems suit high-end servers, communications equipment, and other applications that need redundant power. Each system consists of two power modules housed in a single chassis/backplane. They provide output power levels from 280 up to 700 W. The redundant power systems offer 3.3-, 5-, 12-, and -12-V as well as 5-VSB output voltages. The 700-W AGL9233-R2U system is housed in a 2U-high enclosure, while the others are in 1U enclosures. The systems provide for hot-swap/redundant functionality of the ac/dc power supply while the backplane's dc/dc regulators feature reliability levels measured in millions of hours to support high-reliability applications.
