Light Path Diagnostics table
Use the following table to help determine the cause of the error and the action you
should take.
Note: Power is available to relight the Light Path Diagnostics LEDs for a short
period of time after the blade server is removed from the BladeCenter 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 blade server is removed from the
BladeCenter 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.
