What is a server rack UPS?

A server rack UPS system is an uninterruptible power supply designed to be installed within a 19inch server rack or cabinet. The rack UPS will typically attach to slide out rails or may be placed onto a suitable supporting shelf within the serve rack. A UPS may be classed as a rack mount UPS or a dual system. A dual server rack UPS can be installed as a rack mount UPS or turned 90degrees to stand as a tower UPS. In the tower format, stabilising feet are normally attached. Care should be take when selecting a server rack UPS to make sure that its depth is less than the depth of the server rack into which it is to be placed. A 500mm deep rack mount UPS will require an 800mm deep server rack or cabinet.
