18.7 The Shutdown Screen
Use this screen to turn off the NSA or perform a software restart. A software restart is faster than
turning the NSA off and then turning it on again. Before shutting down or restarting, check the
System Status > Active Sessions screen to make sure that no one is logged into the NSA or
transferring files to or from the NSA.
