Light path diagnostics panel

For quick problem determination when you are physically at the server, the compute node offers a 3-step

guided path:

The Fault LED on the front panel

The light path diagnostics panel

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.

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.
