D-Link DPR-1020 User Manual

Setting up the DPR-1020 

 

 

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.
