Schneider Electric 66123, 66124 Shutdown criteria managed by the Network Management Card

7.2Shutdown criteria managed by the Network Management Card

During an extended power failure, three criteria may cause the server shutdown procedure to be initiated. If several criteria are selected, (See

page Shutdown parameters), the first criterion encountered will launch the shutdown procedure.

7.2.1Backup time before initiating the shutdown procedure (Shutdown After - Shutdown Timer)

When the UPS switches to battery, the Network Management Card starts the Shutdown Timer countdown and launches the system shutdown procedure at the end of the countdown.

This value must be chosen so that users have time to complete their tasks and disconnect, without exceeding battery backup time.

Note 1:

The Network Shutdown Module can also manage its own Shutdown Timer (configurable in the Shutdown Module"set-up" menu of each Network Shutdown Module) launched when the UPS switches to battery.

Note that if this criterion is selected to initiate system shutdown, automatic system reboot when power is restored is not guaranteed (e.g. power restoration if only this system was shut down).
