Light path diagnostics panel

For quick problem determination when you are physically at the server, the compute node offers a 3-step
guided path:
1.
The Fault LED on the front panel
2.
The light path diagnostics panel
3.
LEDs next to key components on the system board
The light path diagnostics panel is visible when you remove the server from the chassis. The panel is at
the upper right side of the compute node, as shown in the following figure.
Figure 9. Location of X6 light path diagnostics panel
To illuminate the light path diagnostics LEDs, power off the compute node, slide it out of the chassis, and
press the power button. The power button doubles as the light path diagnostics remind button when the
server is removed from the chassis. The meanings of the LEDs are listed in the following table.
