7.3System ID LED and System Status LED
The server board provides LEDs for both system ID and system status. These LEDs are located in the rear I/O area of the server board between the PS/2 mouse/keyboard stacked connectors and the video/serial stacked connectors. The location of these LEDs is shown in the following figure.

Figure 20. System ID LED and System Status LED Locations
The blue System ID LED can be illuminated using either of the following two mechanisms.
By pressing the System ID button on the system front panel, the ID LED displays a solid blue color until the button is pressed again.
By issuing the appropriate hex IPMI “Chassis Identify” value, the ID LED either blinks blue for 15 seconds and turns off or blinks indefinitely until the appropriate hex IPMI Chassis Identify value is issued to turn it off.
