5.1.3 Protection of a server connected to a controlled outlet
Network Shutdown Modules (NSM) starting with version 3.0 are compatible with the controlled outlets.
After connecting the server electrically to one of the controlled outlets, the NSM must be informed of the outlet number to which it is
connected.
Refer to the documentation of the NSM available on the internet site

5.1.3.1 Load shedding or sequential shutdown
It is possible to optimise backup time by shutting down non-priority equipment or sequencing the shutdown of several devices.
Two shutdown criteria are possible:
Z
Shutdown of outlets after a set battery back-up time (After)
Z
Shutdown of outlets at a given battery discharge level (if battery capacity under)
It is possible to specify values for both criteria. The first criterion reached will initiate server shutdown.
5.1.3.2 Sequential startup
It is possible to delay outlet power-on to reduce inrush currents on startup or to sequence the startup of several devices.
Controlled outlet startup after a given time is based on startup of the main outlet.
