Power On Self Test - D-Link AirPlus G DP-G301 Manual

Power ON Self-Test
Every DP-G301 has been factory-tested to operate properly.
When the DP-G301 is powered
each of its major components. The final result of the Self-Test is signaled by the
state of the LPT LED indicator following the Self-Test. Preliminary to the actual
component tests, the LED indicators are tested to confirm their steady and flashing
operation.
Immediately after power-up, three of the green LEDs should illuminate steadily for
several seconds. Irregularity of the LED during this LED test may mean there is a
problem with the LED itself.
The actual component tests immediately follow the LED tests. A normal (no fault)
result is signaled by a flashing of the LPT LED, followed by a darkened LED.
If the Self-Test routine detects 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.
