Light path diagnostics
Light path diagnostics is a system of LEDs on various external and internal components of the server that
leads you to the failed component. When an error occurs, LEDs are lit along the path of the front panel, the
light path diagnostics panel, then on the failed component. By viewing the LEDs in a particular order, you
can often identify the source of the error.
When LEDs are lit to indicate an error, they remain lit when the server is turned off, provided that the server is
still connected to power and the power supply is operating correctly.
