UPSUTIL Commands
Chapter 32
255
• High Battery Voltage — The UPS device reported a High Battery Voltage status, which indicates that the
UPS control module perceived an overvoltage at the battery terminals, indicative of a hardware problem.
• Low Battery Voltage — The UPS device reported a Low Battery Voltage status, which indicates that the
UPS control module perceived an undervoltage at the battery terminals, indicative of a hardware
problem.
• High Output Voltage Shutdown — The UPS device reported a High Output Voltage Shutdown status,
which indicates that the UPS control module perceived a severe overvoltage at its AC power output
terminals, and consequently shut-down its power circuits to prevent damage to itself and to the system
component(s) receiving power from this UPS.
• Low Output Voltage Shutdown — The UPS device reported a Low Output Voltage Shutdown status,
which indicates that the UPS control module perceived a severe undervoltage at its AC power output
terminals, and consequently shut-down its power circuits to prevent damage to itself and to the system
component(s) receiving power from this UPS.
Additional Examples
The following examples illustrate various conditions of the UPS Monitor Process and of the UPS hardware
devices that can be observed by using the STATUS command.
Example #2 — UPS Monitor Not Running
This example shows the display of the STATUS command when given at a time at which the UPS Monitor
Process is not running.
If you get this result from a STATUS command, you know that the UPS Monitor Process is currently not
running. You can start the UPS Monitor Process running by using the START command, if desired.

Example #3 — AC Power Failure In Progress
This example shows a status display typical of an incoming AC power failure condition at one of the UPS
devices.
In this case, you can see in the UPS MONITOR PROCESS STATUS that the System Power State is “Power
has failed,” and that the configured “Powerfail Grace Period” timer is now running.
The UPS DEVICES STATUS portion of the display shows that UPS LDEV #23 has reported an “AC Power
Fail” hardware status condition, and so its Power condition field has been changed to Failed.
