NTAK09 LED states during self-test
Action LED State
Power up system Top five LEDs light for eleven seconds.
Self-test in progress Top five LEDs go out for one second.
If the self-test passes, the top five LEDs flash
on and off three times.
If the self-test detects a partial failure, the top
five LEDs flash on and off five times.
When the self-test is completed, the LEDs are
set to their appropriate states.
NTAK20 power on self-test
The clock controller daughterboard LED is the second LED from the bottom
on the faceplate of the NTAK09 DTI/PRI card.
When power is applied to the NTAK20 clock controller, the LED is initially
off for two seconds. If the self-test passes, the LED turns red and flashes
on and off twice.
When the self-test is completed, the LED remains red until the clock
controller is enabled. When enabled, the clock controller LED either turns
green or flashes green.

NTAK93 self-test
The NTAK93 DCHI daughterboard LED is the bottom LED on the faceplate
of the NTAK09 DTI/PRI card.
The NTAK93 DCHI daughterboard does not perform a self-test when power
is applied to it. When power is applied, it turns red and remain steadily lit,
indicating the DCH is disabled. When the DCH is enabled, the LED turns
green and remains steadily lit.
