Power Source

Your system has one or more power cords that supply electrical power to your system's power supply and other components. 

Redundancy Status The possibilities for redundancy status are unknown, full, and lost. Unknown means that the instrumentation is not reporting a status for this component. Full means that the minimum number of power cords plus one backup cord is operational. Lost redundancy in a system that requires two power cords for full redundancy means that only one power cord is working. The one power cord required for operation does not have a backup.
Number of Devices Required for Full Redundancy Defines the total number of power cords required for this system to have full power redundancy. Equal to the number of power cords required for operation + 1. 
Redundancy Mode Indicates whether the system is configured to have redundant power or not. Options are redundant and not redundant.

Redundant means that the system is expecting power cord redundancy.

Not redundant means that the system is not expecting power cord redundancy.

Redundancy Configuration Indicates the currently configured mode of switching behavior.
Input source Line 1, upon redundancy restoration, remain on Line 2 means that if the system is using Line 1 and a power interruption occurs on Line 1, the system switches to Line 2; after power is restored to Line 1, the system remains on Line 2.
Input source Line 1, upon redundancy restoration, return to Line 1 means that if the system is using Line 1 and a power interruption occurs on Line 1, the system switches to Line 2; after power is restored to Line 1, the system returns to Line 1.
Input source Line 2, upon redundancy restoration, remain on Line 1 means that if the system is using Line 2 and a power interruption occurs on Line 2, the system switches to Line 1; after power is restored to Line 2, the system remains on Line 1.

AC Power Lines

Status For each power source, whether the component has a Normal, Warning, or Critical/Failure event type.
Location Description of the AC power line; for example AC Power Line 1, AC Power Line 2.
AC Present Whether power is present in the line number or not. Options are power present and power not present.
Active Source Whether the power source is active or not. Options are Active and Not Active.
