Locator Switch/LED (Unit Identifier or 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 2 MP and LOC commands,
lights the rear panel LED, and vice versa.
• Off = Off
• Blue (Not flashing) = Identification
System Insight Display 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 5-1 shows the System Insight Display LEDs.
