Operating Mode

[CDiggin]

Describes the current operating state of the UPS, which may require attention. The states are indicated by color:

• Red indicates a Critical state.
• Yellow indicates a Warning state.
• Blue indicates an Informational state.
• Green indicates a normal UPS state.

• On Line
• On Battery
• Low Battery
• Bypass
• UPS Off

Status	Description	Severity
On Line	Estimated Runtime The UPS is connected to utility power, the battery is charging, and the UPS is operating normally. The estimated runtime is the number of minutes the connected devices (load) can be supported by the UPS battery in the event of a power outage. Device Health Critical A critical health event is occurring.	Not Applicable
On Battery	Estimated Runtime Input utility power is interrupted, and the UPS is supporting its load on battery. The estimated runtime is the number of minutes the load can be supported by the UPS on battery. Runtime Calibration Initiated The UPS is performing a battery calibration to determine an accurate reading of battery runtime available. The calibration is initiated from PowerChute Serial Shutdown, or via the UPS LCD. See Knowledge Base article  FA284198 for more information on runtime calibration.	Warning Informational
Low Battery	Estimated Runtime The UPS operating on battery has reached the Low Battery Threshold, which is configured via the UPS LCD or via PowerChute Serial Shutdown or Network Shutdown. If the UPS runtime remaining falls below the Low Battery threshold, and if input power is not restored to the UPS, it will shut down when the battery has exhausted.	Critical
Bypass	UPS Initiated Bypass The UPS is reporting an internal hardware issue that has caused the UPS to switch to bypass operation. User Initiated Bypass A user has placed the UPS into bypass mode, which allows maintenance to be performed without turning off utility power to the UPS.  NOTE:  This option is not available for all UPS models	Critical Warning
UPS Off	Output Power Turned Off The UPS output is turned off, and is no longer supporting any connected devices.	Informational
