Power On Self-Test - D-Link DP-313 User Manual

Power On Self-Test

When the Print Server 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 LPT1, LPT2, and LPT3 LED indicators
following the self-test. Preliminary to the actual component tests, the
three LED indicators are tested to confirm their steady and flashing
operation.
Immediately after power-up, all five of the LED's should show steady
green for several seconds. Then the LPT1, LPT2, and LPT3 LEDs
should flash on simultaneously three times. Irregularity of any of the
three LEDs during these LED tests may mean there is a problem with
the LEDs themselves. Contact your dealer for correction of any LED
problems before proceeding.
The actual component tests immediately follow the LED tests. A
normal (no fault) result is signaled by a series of three cycles of
sequential flashing of the three LEDs, 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 LED's 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.
