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
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.
|
---|---|
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. ![]() ![]() ![]() ![]() |
---|---|
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. |
Firmware Version | Indicates the firmware version of the individual power supply. |
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
Use this window to configure the alerts that you want to take effect in the event of a power supply warning, critical/failure, or loss of redundancy.

Status Definitions For Power Supplies And Power Redundancy Units
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. |
