summary

The ProLiant DL580 G2 server is a 4U (7-inch) high unit designed for installation in a

standard 19-inch rack. The installation of a multi-unit system can place significant

demands on utility power that, if not considered and managed appropriately, can result

in downtime due to equipment failure, power main failure, or both. Power management

becomes a critical element in an enterprise system handling large volumes of data

and/or users where downtime costs can easily run into thousands of dollars per hour.

Note: This document discusses only HP products and solutions although the information

and ideas presented herein may be applicable to third party hardware.

description

high voltage 180-264 VAC (200-240 VAC nominal) supplied to areas where

load requirements are such that high voltage is more economical.

Common in commercial applications in North America, numerous

foreign countries also use this range as the AC appliance

standard.

inrush current A high, momentary current draw occurring when power is first

applied to electrical systems. This current drain is not relative to

the power-on requirements of equipment but instead is due to the

capacitive and inductive properties of components in the power

supply.
