System Insight Display LEDs
The System Insight Display improves serviceability by enabling you to look in a single location for
the LEDs that provide failing CRU locating/mapping information. These amber LEDs are only lit
when a failure occurs; otherwise, they are off. The System Insight Display is located on the front
panel of the server. A diagnostic LED exists for each CRU in the system, including all DIMMs.

In addition to the front panel diagnostic LEDs, CRUs provide additional diagnostic capability
through 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 determines the front panel color.
Diagnostics
A suite of offline and online support tools are available to enable manufacturing, field support
personnel, and the customer to troubleshoot system problems. In general, if the operating system
(OS) is already running, it is not desirable to shut it down, and the online support tools should be
used.
If the OS cannot be booted, then the offline support tools should be used to help resolve the problem.
The offline support tools are available either from the EFI partition, or from the IPF Offline Diagnostics
and Utilities CD (IPF systems only). Once the problem preventing booting has been resolved, the
OS should be booted, and the online support tools should be used for any further testing.
If it is not possible to reach EFI from either the main disk or from a CD, you must troubleshoot,
using the visual fault indicators, console messages, and system error logs that are available.
