Locator Switch/LED (UID)

The locator switch/LED allows a specific system to be identified in a rack or Data Center
environment. One locator switch/LED is located in the front panel, and a second is located in the
rear of the server. LEDs are incorporated inside the push-button to minimize space. Both switches
are toggle switches, meaning you push it once to turn on the LED, and you push it again to turn
off the LED. Pressing the front panel Switch/LED, or entering the iLO 3 MP and LOC commands,
lights the rear panel LED, and vice versa.
Off = Off
Blue (Not flashing) = Identification

SID LEDs

The System Insight Display improves serviceability by allowing 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.
Figure 7 shows the System Insight Display LEDs.

CRU health is assumed good.
CRU health last known to be bad.

FRU and CRU health LEDs

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 UEFI 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 UEFI 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.

Online diagnostics and exercisers

Online support tools are available which permit centralized error archiving, and which provide
hardware inventory tools, as long as the agents/providers that support them are installed on the
managed server.
On HP-UX systems, the legacy tools within OnlineDiag are supported. The online support tools, on
the HP-UX 1 1.23 and greater operating systems, include the WBEM features added by
SysFaultMgmt.
