System Identification Indicators
The identification buttons on the front and back panels can be used to identify a particular system within a rack. See Figure 2 -2 to locate the front-panel
system identification button. See Figure 2 -3 to locate the back-panel system identification button and indicator.
When either of the identification buttons is pushed, the identification indicator on the back blinks until one of the buttons is pushed again. If the bezel is
installed, the system status indicator will also blink. If an indicator is connected to the back-panel system status indicator connector, that indicator will also
blink.
Systems management software can also be used to cause the status and identification indicators to blink to identify a particular system. For more information,
see the systems management software documentation.
Front-Panel Indicators and Features
Additional indicators are located behind the bezel. The front-panel status LCD provides information using an alphanumeric character display (see " LCD Status
Messages "). See Figure 2 -2 for the front-panel indicators and features.
Figure 2 -2 shows the front-panel features of the system. Table 2 -2 describes the front-panel features.
