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 passive midplane (in the passive system - see Figure 4) or active midplane (in the active 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 SR1625UR 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 passive midplane (in the passive system - see
Figure 4
) or
active midplane (in the active system - see
Figure 5
) help identify failed and failing
fans. The fan fault LEDs turn on (amber) if there is a fan fault.
