commands, lights the rear panel LED, and vice versa.

Diagnostics Panel LEDs
The Diagnostics Panel improves serviceability by allowing you to look in a single location for the
LEDs that provide failing FRU locating/mapping information. These amber LEDs are only lit when
a failure occurs; otherwise, they are off. A label on the panel is oriented in a fashion analogous
to the orientation of the components within the server: a diagnostic LED exists for each FRU in
the system, including all DIMMs.
LED locations are presented in
Figure 50 Diagnostic Panel LEDs
lists the diagnostic panel LED states.

Customer Replaceable Unit Health LEDs
In addition to the front panel diagnostic LEDs, customer replaceable units (CRUs) provide
additional diagnostic capability with LEDs, whose order or layout is product dependent.
NOTE:
If multiple error conditions occur, all applicable CRU lights are activated. In such a
case, the most critical error will determine the front panel color.
