Locator LED
The locator LED, or unit identifier (UID) allows a specific server blade to be identified in a rack or
data center environment. One Locator LED is located in the front panel.

NOTE: When the UID is lit, this also indicates that the BMC is working properly.
Server Health LED
The server blade uses the Server Health LED for the following reasons:
• To carry forward the Attention functionality of legacy Integrity front panel designs.
• To indicate whether the server is on or off.
• To provide a visual alert for faults that software/firmware is not sure if a FRU must be
reseated/replaced.
The server health LED indicates the overall health state of the server blade, including the state of
server firmware and the OS. If the LED is amber or red, the server blade needs attention. Examine
the event logs (on iLO 2 MP) for details of the problem. Table 17 details the functions of the health
LED.
