Protection Applications
NetWatch and NSM protection applications send the following essential data to the card:
l
l
IP Address or hostname of the server on which it is installed so that the card can inform the application of
power events.
Time required to shut down the server (Shutdown Duration, configurable in the ”Set-up” menu of each
NetWatch and NSM application).
The card takes into account the longest shutdown time of all the Network Shutdown Modules subscribed
(Shutdown duration of the Shutdown parameters) page to manage UPS shutdowns without affecting any
connected Shutdown Modules.
During normal operation, the protection application periodically checks its connection with the card. In case of
a major power event, the card sends information to the protection application, which responds according to
the situation:
l
Shutdown order
l
Programmed actions
l
Messages to the administrator and to users through the network
When the server shuts down, the protection application unsubscribes itself from the Notified Applications list.
See “Notified Applications” on page 40 for more information.
Shutdown Criteria Managed by the Network Card-MS
During an extended power failure, three criteria can cause the server shutdown procedure to be initiated. If
multiple criteria are selected, the first criterion encountered launches the shutdown procedure. See Table 27
for criteria descriptions.
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.
NOTE
See “Shutdown Parameters” on page 29 to configure the shutdown parameters.
