4.2.1. Start-up and Flow Screens
At start-up, the UPS executes a system test and displays the Vertiv logo screen for about 30 seconds, shown
in Figure 4-1 on page 53 . After the test completes, an overview screen shows status information, the active
(green) power path, and the inactive power path (gray).
