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 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.
