Intel® Light-Guided Diagnostics The server system contains the following diagnostic LEDs, each providing the following functions: • The System Status LED on the front and back panels (see Figure 3 and Figure 6) shows the overall health of the system (green, blinking green, blinking amber, amber, off) . • The System Identification LED on the front and back panel (see Figure 3 and Figure 6) helps identify the server from among several servers. The ID LED is off by default, and blue when activated by button or software. • DIMM Fault LEDs on the server board (see Figure 3) help identify failed and failing DIMM slots. The DIMM fault LEDs turn on (amber) if there is a DIMM fault. • POST Code Diagnostic LEDs on the server board (see Figure 3) change color or state (off, green, red, amber) according to the POST sequence. • The 5V-STBY LED on the server board (see Figure 3) is illuminated (green) when AC power is applied. • Fan Fault LEDs on the fan board (in the fixed mount hard drive system - see Figure 4) or hot-swap backplane (in the hot-swap hard drive system - see Figure 5) help identify failed and failing fans. The fan fault LEDs turn on (amber) if there is a fan fault. 10 Intel® Server System SR1600UR Service Guide

Light-Guided Diagnostics
The server system contains the following diagnostic LEDs, each providing the following
functions:
•
The System Status LED on the front and back panels (see
Figure 3
and
Figure 6
)
shows the overall health of the system (green, blinking green, blinking amber,
amber, off) .
•
The System Identification LED on the front and back panel (see
Figure 3
and
Figure 6
) helps identify the server from among several servers. The ID LED is off
by default, and blue when activated by button or software.
•
DIMM Fault LEDs on the server board (see
Figure 3
) help identify failed and failing
DIMM slots. The DIMM fault LEDs turn on (amber) if there is a DIMM fault.
•
POST Code Diagnostic LEDs on the server board (see
Figure 3
) change color or
state (off, green, red, amber) according to the POST sequence.
•
The 5V-STBY LED on the server board (see
Figure 3
) is illuminated (green) when
AC power is applied.
•
Fan Fault LEDs on the fan board (in the fixed mount hard drive system - see
Figure 4
) or hot-swap backplane (in the hot-swap hard drive system - see
Figure 5
)
help identify failed and failing fans. The fan fault LEDs turn on (amber) if there is a
fan fault.
