NTAK09 DTI/PRI power on self-test
When power is applied to the NTAK09 DTI/PRI circuit card, the card
performs a self-test. The LEDs directly associated with the NTAK09 circuit
card are DIS, ACT, RED, YEL, and LBK. The clock controller LED is also
included in the power on self-test.
Table 318 "NTAK09 LED states during
provides the state of the NTAK09 LEDs during the
self-test procedure.

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.
