Light path diagnostics panel

For quick problem determination when you are physically at the server, the x222 Compute Node offers a
three-step guided path:
1.
The Fault LED on the front panel of each server
2.
The light path diagnostics panels, one for each server, as shown in the following figure
3.
LEDs that are next to key components on the system board
The two light path diagnostics panels on the x222 are visible when you remove the server from the
chassis. One panel is for the upper server and one is for the lower server.
Figure 10. Location of x222 light path diagnostics panels
To illuminate the light path diagnostics LEDs, power off the server, 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 in the light path diagnostics panel are listed in the following table.
