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.
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. If the number of power supplies in a system that is required for
full redundancy is three: Redundancy Status is Full when three power supplies are working. Redundancy Status is Lost with a status of Noncritical when two power supplies are working. Redundancy Status is Lost with a status of Critical when only one power supply is working. 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. |
Status | Power supply status
is indicated by the status icon for components. A green check mark ( ![]() ![]() ![]() |
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). |
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. |
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.

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 nonredundant power supplies fail, no power is delivered to the system. |
