Status LED
The actual status LED is part of the system controller assembly, which is located behind
the front panel. A piece of light-conductive plastic (light pipe) channels the light from the
LED to the front panel.
When the master power switch is turned on, the status LED flashes green briefly, but
does not stay illuminated. When the system boots, the LED flashes red momentarily, then
turns green.
For a complete list of status LED codes, see "Status LED Messages" in Chapter 9.
