Power Switch, System LEDs, and Light Pipe
The power switch and system LEDs are mounted to the front of the base unit chassis. A light pipe
secured to the faceplate guides the light from the LEDs to openings on the faceplate. See the
System Board Manual for power switch and LED connector locations and details.
