4.2.1 Extended power outage, shutdown initiated by the Shutdown Timer
During battery backup time, the Shutdown Timer of the Network Management Card is reached: after a user-
defined backup time period, 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).
Z Shutdown Duration: Maximum value of shutdown times of the Network Shutdown Modules and UM-
Clients subscribed to the card and depending on the main UPS outlet. This value is updated each time a
client subscribes/ unsubscribes.
Z Shutdown Duration 1 (2): Maximum value of shutdown times of the UM-Client subscribed to the card and
dependent on outlet 1 (2). This value is updated each time a UM-Client dependent on outlet 1 (2)
subscribes /unsubscribes.
