Using the Front Panel DisplayThe front panel display shows several important things (see Figure 48). The numbers in the upper left corner (for example, 3 19) are the display location within the operating menu structure. The word in the top center (for example, USER ) is the security level, which allows various operating parameters to be changed.

The number in the upper right corner (for example, #2) identifies the cabinet slot (numbered from the top down) for a specific power module's parameters. #0 is defined as System, enabling you to observe overall system operation.
One or two triangles at the right of the display tells you which arrow buttons are active for moving to various parameters within a menu level. See Figure 50 on page 68 for the complete system menu.
The words or symbols in the bottom line of the display define the function of the three buttons below the display. In Figure 48, Slot (button A) enables you to observe the operation of a specific power module (the module in slot #2, in this case) or the overall system (selected as slot #0). Top (button B) takes you to the top item in the current menu level (in this case, 3 1). And ESC (button C) enables you to move out of the current menu level (in this case, to menu 3).
During normal operation, the display appears as shown in Figure 49. Md: indicates the current UPS operating mode and St: indicates the operational state.
