EMU indicator displays
The EMU status indicators are located above the alphanumeric display. See Figure 13 (page 33).
These indicators present the same information as those on the front, lower right corner of the
enclosure.
You can determine the EMU and enclosure status using the information in Table 10 (page 35).

Using the alphanumeric display
The two-character alphanumeric display is located at the top of the EMU (see Figure 13 (page
33)). This seven-segment display provides information about multiple enclosure functions. The
push-button control the data displayed or entered.
Alphanumeric display description
The top-level, two-character alphanumeric display (En, Li, rG, Au, and Er), is the display group.
The function of the other displays is display-group dependent. The default display is the enclosure
number, a decimal number in the range 00 through 14. The push-button allow you to select the
alphanumeric display or to enter data.
• The bottom push-button sequentially moves between groups and selects a display group.
See Table 11 (page 36) for a description of these display groups.
• he top push-button moves between the levels within a display group (see 2, Figure 13 (page
33)).
Display groups
When you press and release the bottom push-button, the alphanumeric display selects a different
display group. Table 11 (page 36) describes the display groups.
