MGE UPS Systems 66102, 66103 Different server and UPS shutdown sequences, Sequential startup

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.

5.2The different server and UPS shutdown sequences

5.2.1Extended power outage, shutdown initiated by the Shutdown Timer (Shutdown after)

During battery backup time, the Shutdown Timer of the Network Management Card is reached: After a user-defined backup time period (Shutdown parameters page), the shutdown of all servers is initiated, followed by the UPS shutdown (depending on its configuration). The UPS restarts when utility power is restored (depending on its configuration)

Shutdown duration: Maximum value of shutdown times of the Network Shutdown Modules subscribed to the card. This value is updated each time a client subscribes/ unsubscribes.

Utility failure	Start shutdown	Start shutdown main	Utility restore
	output 1	output
Utility
Main output
	Shutdown after:	Shutdown duration
		main output
NSM 1 on main

	Shutdown after 1:

NSM 2 on output 1

5.2.2Extended power outage, shutdown initiated by the "Low battery power" message

When the "Low battery power" criterion is displayed, the UPS is shut off after taking into account the shutdown duration of the servers.

"Low battery power": The message appears if either of the two following criteria is checked:

-Low Battery Level

-Low Battery Delay
