¹Selecting this option might result in an ungraceful shutdown. The amount of remaining runtime cannot be accurately predicted after a low battery warning is issued.
² Running batteries to depletion can cause an ungraceful shutdown if a second power failure occurs before the batteries have fully charged.
4.Enter the amount of time to wait before restarting the attached device in the Restart Settings column. This option allows utility power to stabilize and disks in shared storage configurations to spin up before the server restarts.

Shutdown Events menu
Click Shutdown Events in the left navigation frame to display the Shutdown Events screen. In addition to the typical events (such as power fail events) causing shutdowns, this screen enables administrators to configure other events to trigger a shutdown.
When a shutdown event occurs, the management module gracefully shuts down all attached devices and UPS load segments.
To specify an event for shutdown:
