NOTE
The illustrations in this document might differ slightly from your hardware.
Figure 5 on page 16 and Figure 6 on page 17 show the LEDs on the system board for the NovaScale
Blade 2021. Refer to Table 1 on page 16 and Table 2 on page 17 for more information about the
Light Path Diagnostics LED locations and settings. Refer to these illustrations and tables when
solving problems with the NovaScale Blade Server.
✏
NOTE
Power is available to relight the Light Path Diagnostics LEDs for a small period of time after
the NovaScale Blade Server is removed from the NovaScale Blade Chassis unit. During that
period of time, you can relight the Light Path Diagnostics LEDs for a maximum of 25
seconds (or less, depending on the number of LEDs that are lit and the length of time the
NovaScale Blade Server is removed from the NovaScale Blade Chassis unit) by pressing the
Light Path Diagnostics button. The Light Path Diagnostics power present LED (CR111)
lights when the Light Path Diagnostics button is pressed if power is available to relight the
blade-error LEDs. If the Light Path Diagnostics power present LED does not light when the
Light Path Diagnostics button is pressed, no power is available to light the blade-error
LEDs, and they will be unable to provide any diagnostic information.
