Rackmount UPS Systems

Rackmount uninterruptible power supplies include single-phase server rack UPS systems from 1kVA upwards and supplied ready for installation into a server rack or 19inch cabinet. The batteries may be internal or supplied in a rackmount battery tray. Long battery runtimes may require additional trays or floor standing battery cabinets. Other options available from Server Room Environments include: automatic transfer switches, rack mount maintenance bypass switches, remote monitoring connectivity and power distribution units.

Rack Mount UPS Sizing

Rackmount systems have three important form factor dimensions to consider when sizing for a rack cabinet. These include the width, depth and height of the cabinet.

Server Rack Cabinet Widths

The standard width for a rack cabinet is 19 or 23 inches. Where the system to be installed is less than this width it may be necessary to either install the system on a pre-fitted shelf or (if available) attach a front plate to the system that will allow it to be bolted to the vertical struts.

Most rack mount systems are supplied with sliding rails. These are attached to the rackmount system and the server rack cabinet and allow the system to be pulled out of the rack for easy maintenance and inspection. Care has to be taken that the slide-out rails are strong enough to support the weight of the system. Where this is not the case a shelf is used.

When installing any system into a rack cabinet, case should be paid to ‘manual handling’ procedures and health & safety. Cabinets should have the heaviest items in their lower sections to prevent the cabinet toppling over and lifting tables may be required to help position systems including larger rackmount UPS and battery trays.

Rack Depth

Each server cabinet has an internal depth (measured front to back) and it is important when selecting a rack mount UPS system to make sure that the UPS depth will fit inside the server rack (including any rear-connected plug-in sockets or cable termination blocks).

Rack UPS Height

Server rack cabinet height is measured in Us where 1U=44mm. Each rackmounted UPS or other system has a U height defined by its dimensions. The U-height dimension allows system designs to specify the right sized rackmount cabinet for the systems or be installed and also to identify the positions for blanking plates which can help with air conditioning air flow and improve energy efficiency.
