Using the Front Panel Display
The 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.

Figure 48. Typical Front Panel Display
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. The number of power modules (M) and number of
battery module strings (B) that are currently online, and the total
number of module slots in the cabinetfor example, M4-B7-12is
shown in the upper right corner of the display. (The count of battery
strings does not include additional battery strings contained in
connected external battery cabinets.)
