Shutdown Settings for Advanced UPS Configurations

With Advanced UPS configurations, PowerChute can monitor multiple UPS setups, including single UPS devices and groups of redundant UPS devices that you have created (see “Advanced UPS Setups”).

For each setup, you need to specify the following:

Field

Description

Number of UPSs required to power load

Set this value to the minimum number of UPSs that must be available to support the equipment that is being powered by the UPSs in the setup.

The value set here will be subtracted from the total number of UPSs in the setup and used to calculate the number of additional (redundant) UPSs.

In redundancy terminology, this is the N in N+x.

This setting is not displayed for UPS Setups with a Single UPS device.

Number of additional (redundant) UPSs

This will appear in a setup with more than one UPS. It represents the number of extra UPSs in the setup. This option is associated with the number of UPS critical events required to trigger shutdown:

Redundancy level	No. of critical events that will trigger a shutdown sequence
N+1	2
N+2	3
N+3	4

Multiple critical events occurring on the same UPS does not impact the above table values.

In redundancy terminology, this is the x in N+x.

This setting is not displayed for UPS Setups with a Single UPS device.

Total number of UPSs in Setup

This is the total of the above two rows and is calculated automatically.

Run Command

When a shutdown sequence is triggered you can configure PowerChute to execute a command file.

Note: If the same command file is configured for each setup and a shutdown sequence is triggered for more than one setup at the same time, the command file is only executed once.

See Shutdown Command Files.

Shut down PowerChute Server

This is enabled by default and is used to gracefully shut down the physical machine running PowerChute.

This option should be disabled if the PowerChute machine is not being powered by the UPS’s in a particular setup, and if it is being used to remotely shut down other servers/ equipment.

Shut down if Redundancy lost

If this option is enabled, when the number of UPS critical events is the same as the number of additional (redundant) UPSs, a shutdown sequence will be triggered.

This option is associated with the number of UPS critical events required to trigger shutdown:

Redundancy level	No. of critical events that will trigger a shutdown sequence
N+1	1
N+2	2
N+3	3

Multiple critical events occurring on the same UPS does not impact the above table values.

This option is not shown if there are no additional (redundant) UPSs. For example, this option will not appear if the number of UPS’s required to power the load is the same as the total number of UPS’s in the group.

UPS Shutdown

Use this option to set the required UPS behavior after connected equipment or servers are gracefully shut down. For more information see UPS Shutdown.
