LED
State
Definition
On (Green) The NTAK09 circuit card is in an active state. No alarm states exist,
the card is not disabled, and it is not in a loopback state.
ACT
Off An alarm state or loopback state exists, or the card has been
disabled. See the other LEDs for more information.
On (Red) A red-alarm state has been detected.
RED
Off No red alarm.
On (Yellow) A yellow alarm state has been detected.
YEL
Off No yellow alarm.
On (Green) NTAK09 is in loop-back mode.LBK
Off NTAK09 is not in loop-back mode.
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 353 "NTAK09 LED states during
self-test" (page 864) provides the state of the NTAK09 LEDs during the
self-test procedure.

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.
