• Does the system shut down after being ON a short time?
— Suspect a thermal-induced shutdown.
— Ensure that the chassis intake and exhaust vents are clear.
— Suspect a power supply failure.
The green OK LED (to the right of the AUX port) should be ON after the system initializes
correctly. (See Figure 3-1.)
