Power On Self-Test - D-Link DP-G310 User Manual

Power ON Self-Test

Every DP-G310 has been factory-tested to operate properly.
When the DP-G310 is powered ON, it also 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 four LED indicators are tested to confirm their steady and
flashing operation.
Immediately after power-up, all four of the green LEDs should illuminate steadily for
several seconds. Then the USB LED should light OFF. Irregularity of any of the four
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 a simultaneous flashing of the USB LED three times, followed
by a quiescent state with the USB LED dark.
If the Self-Test routine traps any component error, then following the LED tests the
Self-Test will halt and the USB LED 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.
