NT8D02 and NTDK16 Digital Line cards

The faceplate of the NTDK16BA digital line card is equipped with three light
emitting diodes (LEDs). A red LED lights when the card is disabled. At
power-up, this LED flashes as the digital line card runs a self-test. If the test
completes successfully, the card is automatically enabled (if it is configured
in software) and the LED goes out. This LED only shows the status of the
NTDK16 in slot 4.

Note: The NTDK16AA has one LED. This LED shows the status of
Card 4. The NTDK16BA has three LEDs. These LEDs show the status
of Cards 4, 5, and 6 configured on the NTDK16.

Digital line cards are housed in NT8D37 Intelligent Peripheral Equipment
(IPE) Modules. Up to 16 cards are supported.

The digital line card circuitry is mounted on a 31.75 cm by 25.40 cm (12.5
in. by 10 in.) double-sided printed circuit board. The card connects to the
backplane through a 160-pin edge connector.

The faceplate of the digital line card is equipped with a red LED that lights
when the card is disabled. See

Figure 124 "Digital line card - faceplate"

(page 504)

. When the card is installed, the LED remains lit for two to five

seconds as a self-test runs. If the self-test completes successfully, the
LED flashes three times and remains lit until the card is configured and
enabled in software, then the LED goes out. If the LED continually flashes
or remains weakly lit, replace the card.
