System Insight Display
The System Insight Display enables you to monitor a single location for the LEDs that provide
failing customer replaceable unit (CRU) locating/mapping information for internal system
components. These LEDs are solid amber in color only when a failure occurs, and are otherwise
unlit (they are not green the rest of the time). The LEDs are visible on the front panel. Diagnostic
LEDs are provided for each internal CRU in the system, including all DIMMs, and system fans.
Figure 1-7 (page 29)
shows the System Insight Display on the front of the server.
