Check that the power cord is securely installed on both
ends.
If no LEDs are on, the power supply may be defective.
Test the outlet to verify power.
If other LEDs are on, the PWR LED may be burned out.
Unplug the unit and reapply power; watch all LEDs during
the power-on self-test to verify that the PWR LED is
functioning. If the problem persists, contact the service
provider.
