5.3 Shutdown management with 2 NMC boards

Certain UPS can have 2 NMC boards in order to:

 Increase the number of protected servers,

 Protect 2 groups of server connected to different networks physically separated.

5.3.1 Shutdown Duration

As described in the 5.1.1.4 paragraph, the protection application transmit their own "Shutdown duration" to the

Network Management Card. Based on these values (maximum Shutdown duration of all subscribed customer

systems) that the card will send to the delayed shutdown order to the UPS.

If the UPS have two NMC cards, the maximum shutdown duration of the two groups of protected systems will be

used for the delayed shutdown order.

Example: If the subscribed customers of the first NMC card have a maximum Shutdown duration of 60s and the

ones of the second NMC card of 120s, the servers shutdown will be launched 120s before the UPS shutoff..

5.3.2 Settings

Set-up shutdown parameters to the same value on the 2 cards are highly recommended (for the main output and

the controlled outlets).

If the settings are not the same, the first criteria reached on one the 2 cards will launch the secure shutdown of all

servers

Please, note that in any case the shutdown of the protected servers will be executed safely.
