Chapter 7 Shutdown

This chapter explains:

S Protection applications

S Shutdown criteria managed by the card

S Load Segments

S Shutdown sequences

Protection Applications

NetWatch and NSM protection applications send the following essential data to the

card:

S IP Address or hostname of the server on which it is installed so that the card can

inform the application of power events.

S 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:

S Shutdown order

S Programmed actions

S 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 44 for more

information.

Shutdown Criteria Managed by the ConnectUPS-MS Card

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 17 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 31 to configure the shutdown parameters.
