Power Restoration Before End of Shutdown Duration

Figure 58 shows a graph of a power restoration before the end of the Shutdown

Shutdown Management With Two ConnectUPS-MS Cards

Some UPSs can have two ConnectUPS-MS Cards to:

S Increase the number of protected servers

S Protect two groups of servers connected to separate networks

Shutdown Duration

The protection application transmits its own shutdown duration to the

ConnectUPS-MS Card (as described in Table 17). Based on these values (maximum

shutdown duration of all subscribed customer systems), the card sends the delayed

shutdown order to the UPS. If the UPS has two ConnectUPS-MS Cards, the

maximum shutdown duration of the two groups of protected systems is used for the

delayed shutdown order.

For example, if the subscribed customers of the first ConnectUPS-MS Card have a

maximum shutdown duration of 60 seconds and the customers of the second

ConnectUPS-MS Card have a maximum shutdown duration of 120 seconds, the

server's shutdown will be launched 120 seconds before the UPS powers down.
