and troubleshoot the UPS. The layout is shown below in Figure 3.1.1.
The UPS is monitored and controlled with a series of menus and submenus. The menu tree
and how to use the buttons to move through it is shown in Figure 3.1.3. For a tutorial on how to
use this panel, see Section 3.3, “Battery Replacement.”
