4 Servers protection

4.1Set-up of the shutdown parameters

The Network Shutdown Module, on protected server boot, subscribes itself automatically to Notified Applications list and sends its essential data:

ZIP address or name of the server on which it is installed, to be notified by the card of any power events

ZTime required to shutdown the server (Shutdown Duration, configurable in the Shutdown Module “set-up” menu):

The card takes into account the longest shutdown time of all the Network Shutdown Modules subscribed to manage UPS shutdown without affecting any of the servers protected.

In case of a major power event, the Shutdown Module receives messages from the card and regularly checks its accessibility. The most important messages can generate actions and are sent back to the administrator and users via the network.

When the server shuts down, the Shutdown Module unsubscribes itself from the Notified Applications.

4.1.1 Shutdown criteria managed by the Management Card

During an extended power failure, three criteria may cause the server shutdown procedure to be initiated. If several criteria are selected, the first criterion encountered will launch the shutdown procedure.

At the end of the shutdown procedure, when all servers have been shut down, the UPS may shut down to avoid unnecessary discharge of its batteries, depending on its configuration.

4.1.1.1 Backup time before initiating the shutdown procedure (Shutdown After)

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.

By default, this value is set to 30 minutes. Since GA release, this criterion is not selected in the default configuration

Note 1:

The Network Shutdown Module can also manages its own Shutdown Timer (configurable in the Shutdown Module “set-up” menu)

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).

By default, this parameter is not selected.

4.1.1.2 Initiating the shutdown procedure when the battery level is lower than: (if capacity under)

When the card detects that the remaining backup time percentage is less than the configured level, the shutdown sequence is started.

By default, the card uses the value set in the UPS.

Note:

Certain types of UPS only accept pre-defined minimum battery level values (e.g. : 20% or 40% for COMET and PULSAR EXtreme). Check the UPS documentation.
