5.2.1 Extended power outage, shutdown initiated by the Shutdown Timer
(Shutdown after)
During battery backup time, the Shutdown Timer of the Network Management Card is reached: After a user-defined
backup time period ( Shutdown parameters page), the shutdown of all servers is initiated, followed by the UPS
shutdown (depending on its configuration). The UPS restarts when utility power is restored (depending on its
configuration)
Shutdown duration: Maximum value of shutdown times of protection application subscribed to the card. This value is
updated each time a client subscribes/ unsubscribes.
