of the server. Power Consumption When determining power requirements, you must consider any peripheral equipment that will be installed during initial installation or as a later update. Refer to the applicable documentation for such devices to determine the power required to support these devices - HP rp8420 | Site Preparation Guide, Third Edition - HP 9000 rp8420 Server - Page 22
Fluctuations Voltage fluctuations, sometimes called glitches, affect the quality of electrical power. Common sources of these disturbances are: • Fluctuations occurring within the facility's distribution system • Utility service low-voltage conditions (such as sags or brownouts) • Wide and rapid - HP rp8420 | Site Preparation Guide, Third Edition - HP 9000 rp8420 Server - Page 23
