Power Supply
The power supply is an electrical system that converts AC current from the wall outlet into the DC currents required by the system components.
Systems can be designed with redundant power supplies to prevent system shutdown due to power supply failure. When extra power supplies are present in a system, being able to see that one or two power supplies have failed enables administrators to replace power supplies and restore redundancy before the last power supply failure causes the entire system to fail.

Power Supply Redundancy
NOTE : The fields listed on this page cover possible configurations. Some fields may not be present on your system.
Redundancy Status Redundancy Status can be Full or Lost. Currently, all systems have n+1 power supplies, where n is the number of power supplies that are required for the system to work under fully loaded and stress conditions.
Redundancy Status is Full when all power supplies are working.
Redundancy Status is Lost with a status of Critical when only one power supply is working or if mixed power supplies are used.
Full redundancy is defined by system specification. Lost redundancy means that there are no backup power supplies available to take over for the minimum number required, but at least one power supply is working.
Number of devices required for full redundancy Your system has a number of power supplies defined for full redundancy. Currently, all systems have n+1 power supplies, where n is the number of power supplies that are required for the system to work under fully loaded and stress conditions. If the number of power supplies required for Full redundancy is three, redundancy is lost when one or two power supplies are working.

Individual Power Supply Elements
Status Power supply status is indicated by the status icon for components. Image indicates that a component is healthy (OK). Image indicates that a component has a warning (noncritical) condition and requires prompt attention. Image indicates that a component has a critical/failure condition and requires immediate attention. Image indicates that the health status of an element is unknown.
Location Displays the location where the power supply is installed.
Type Type of power supplied to the system. Type can be AC, DC, or from the voltage regulator module (VRM).
Rated Input Wattage Displays the input power rating for all power supplies on the system.
Maximum Output Wattage Maximum wattage that the power supply can deliver.
Online Status Indicates if the power supply is currently delivering power to the system (online) or whether the power supply is not supplying power (offline).
Example online status values for a power supply in normal condition are:
AC Power on, AC Power Switch on, PS OK, PS On, PS Fan OK, Presence Detected
Example online status values for a power supply in critical condition are:
AC Power off, AC Power Switch on, PS Failure, PS Off, PS Fan Failure, Failure Detected, AC Lost
Power Monitoring Capable Displays Yes if the power supply has power monitoring capability and No otherwise.

Power Supply and Power Redundancy Alert Management
NOTE: Due to the limitations of the VMware® ESXi operating system, the Setting Alert Actions feature is not available in this release of OpenManage Server Administrator.
Use this window to configure the alerts that you want to take effect in case of a power supply warning, critical/failure, or loss of redundancy event.

Status Definitions for Power Supplies and Power Redundancy Units
Event Description
Power Supply Warning Indicates a power supply condition that should be addressed soon or at the next scheduled maintenance.
Power Supply Critical Power supply is operating outside of wattage limits. Take power supply offline.
Power System Redundancy Degraded The number of operational supplies has fallen below the number required for full redundancy.
Power System Redundancy Lost The number of operational power supplies has fallen below the number required for partial redundancy (redundancy degraded). Only the minimum number of power supplies required by the system is operational. In the event that the non-redundant power supplies fail, no power is delivered to the system.
