Shutdown
In PowerChute Serial Shutdown, shutdowns can be initiated:
Shutdowns can also be initiated manually through the UPS LCD or from “outside” PowerChute, e.g. from the Network Management Card (NMC). However, using the NMC in conjunction with PowerChute Serial Shutdown is not supported.
Shutdown Settings
This screen summarizes your shutdown configuration and also enables you to configure some steps of the shutdown sequence.
The summary includes timing and delays, with the “base time” being the occurrence of the On Battery event.

The options chosen on this screen can affect the configuration of events, set up in
Event Configuration. This can include which events are selected to cause a shutdown. Read the other sections below for further information.

Simple Signaling Limitations
The PowerChute Serial Shutdown supported configuration for Simple Signaling is described in the
PowerChute Serial Shutdown Installation Guide. In this configuration, an Interface Expander 2 Card (IE2) can be used to provide a graceful system shutdown for up to three network servers (or other devices) during a power outage, by using only one UPS and simple signaling. In the event of a power outage, all connected servers shut down at the same time.
In the supported configuration, a Master Server is connected directly to the smart computer interface of the UPS, and up to two Slave Servers can be connected to the UPS via the IE2 card basic ports.
NOTE: Some Type B UPS devices with the SRC and all UPS devices with SRV prefixes do not support simple signaling. For example: SRC1KI, SRC2KI, SRC1KI-IN, SRC1KUXI, SRVLPM1KRIL, SRVLPM2KRIL, and SRVLPM3KRIL etc.

You can use PowerChute to configure when a shutdown should occur through the Shutdown Settings page. Due to the nature of simple signaling, there are limitations to the shutdown features available, when compared with a standard configuration:
• IMPORTANT: You must make sure that all PowerChute Agents running on the servers in a Simple Signaling configuration have the same settings to ensure a graceful shutdown:
– The Power Outage Configuration must be the same for each Agent.
– Different command files may be used on each Agent, but they must use the same Time required for command file to run.
• If you disconnect a communication cable in an active simple signaling configuration, PowerChute will not detect the disconnected cable, and you will experience unexpected shutdown behavior. Disconnecting communication cables during simple signaling is not supported. If you need to disconnect a simple signaling cable, manually shut down the connected server first.
NOTE: Do not edit the shutdown settings in the PowerChute UI when the IE2 card is in timer mode as PowerChute relies on the default configuration (“When the UPS signals the Low Battery event”) to shut down the connected servers in this mode. The PowerChute shutdown settings should only be modified when the IE2 card is in confirmed mode. For more information on the IE2 modes of operation, see Knowledge Base article
FA156051.
Provide a high delay in the
Time for operating systems to shut down field in the
Shutdown Settings screen in the Master Server. Setting a high value here will give the operating system more time to shut down.
Connect all servers, including the simple clients, to a PowerChute outlet group. Doing this will ensure that the servers turn off in accordance with the Outlet Sequence screen in the Master Server.
After the Interface Expander 2 card issues a shutdown command to simple clients, a turn off command is also issues to turn off the UPS. To ensure graceful shutdown, the delay of this turn off command is forced to be equal to the values set for
Time for operating systems to shut down and
At runtime limit in the
Shutdown Settings screen of the Master Server.
Set the At runtime limit value in the Master Server appropriately, as this decides the turn off delay of the UPS.
Power Outage Configuration
The options define the response when a power problem causes the UPS to switch to battery operation.
• initiates a shutdown when the UPS has been operating on battery power for the period of time configured here.
• initiates a shutdown when the UPS signals that the Low Battery event has occurred. In a Simple Signaling configuration, this can impact a slave server when the Master Server connected to the UPS signals to all slave servers connected to the Interface Expander 2 Card that it is shutting down. For more information on Simple Signaling configuration, see the
PowerChute Serial Shutdown Installation Guide. This is the default power outage configuration in a simple signaling configuration.
NOTE: For Type B UPS devices, the value set for
At runtime limit in the
Shutdown Settings screen is also added to the UPS turn off delay.
• relies on the Low Runtime Warning event to cause a shutdown.
The Low Runtime Warning event is generated when battery runtime falls below the combined time configured for Application and Operating System shutdown: see the section of this screen.
NOTE: This Low Runtime Warning event does not display on the
Event Configuration screen as it is not configurable (because it
always causes a shutdown).
When you select different radio button options here, the displayed summary information on this screen (under the heading) changes.
Power Outage Configuration and Shutdown on Event Configuration
Choosing one of the four options on Shutdown Settings (discussed above) works interactively with the Event Configuration checkboxes for different events.
You can see this by selecting a radio button option here, pressing Apply, and going to the
Event Configuration screen to note the differences.
This is also true in reverse: changing a checkbox for an event in Event Configuration can change which radio button option is selected here on Shutdown Settings.
If the check box is selected, a warning appears on the screen to inform you of this.
This table summarizes the interaction:
With this On Battery option selected: | ...the Shutdown checkbox of these events is selected |
Low Battery | On Battery | Time on Battery Threshold Exceeded |
Immediately | No | Yes | No |
After UPS has been on battery for | No | No | Yes |
When the UPS signals the Low Battery event | Yes | No | No |
Do not shut down in the event of a power outage | No | No | No |
For example, if you choose here and apply it, you will see in the row of that the checkbox has been selected automatically.
And if you then clear the checkbox for the event of Event Configuration, apply it, and return here to , the option will NOT be the selected option.
Interactivity in shutdown durations
Another field on this
Shutdown Settings screen, under Operating System and Application Shutdown, interacts with thefield for the event on
Event Configuration. When they are changed, these fields automatically update each other.
(Note that the Time required for command file to run field only displays on Shutdown Settings when you have chosen a command file).
• If you have only Switched Outlet Groups, then the group supplying power to the PowerChute Agent always shuts down and ALL other groups have a choice of whether to be shut down or not.
