Intel® Light Guided Diagnostics The server board contains numerous LEDs providing the following functions: • Fault LEDs help identify failed and failing components. The fault LEDs turn on (amber) if there is a memory or processor fault. • The System Status LED that shows the over all health of the system (green, blinking green, blinking amber, amber). • POST Code Diagnostic LEDs change color or state (off, green, red, amber) according to the POST sequence. • The ID LED helps identify the server from among several servers. The ID LED is off by default, and blue when activated by button or software. • The 5V-STBY LED is always illuminated (green) when AC power is applied. A B C D G E F AF002160 Figure 8.
