Power On Self-Test - D-Link DPR-1020 Manual

Setting up the DPR-1020

Power ON Self-Test

Every DPR-1020 has been factory-tested to operate properly.
When the DPR-1020 is powered ON, it automatically performs a Self-Test on each of
its major components. The final result of the Self-Test is signaled by the state of the
USB LED indicator following the Self-Test. Preliminary to the actual component tests,
the three LED indicators are tested to confirm their operation.
Immediately after power-up, all three of the blue LEDs should illuminate steadily for
several seconds. Then the USB LED should light OFF simultaneously. Irregularity of
any of the three LEDs during these LED tests may mean there is a problem with the
LEDs themselves.
The actual component tests immediately follow the LED tests. A normal (no fault)
result is signaled by simultaneous flashing of the LEDs three times, followed by a
quiescent state with all three LEDs dark.
If the Self-Test routine traps any component error, then following the LED tests the
Self-Test will halt and the LEDs will continuously signal the error according to the
following table. In the event of any such error signal, contact your dealer for
correction of the faulty unit.
