3. Slide the DSL card into the slot. Gently but firmly push the card until it
properly seats in its mating connectors on the backplane.
CAUTION:
Do not force the DSL card into the slot. If it does not seat properly,
remove the card and reinstall it. If it still does not seat properly, call
service.
4. The DSL card will now perform a power-up self-test. All of the LEDs turn ON
and OFF briefly. When the self-test is completed successfully, the SYSTEM
OK LED will turn ON. Make sure the SYSTEM OK indicator on the DSL card
faceplate is ON (winking green).
For a more detailed explanation of LEDs on the DSL card, refer to the
appropriate DSL card documentation.
5. Secure the DSL card by fastening the top and bottom screws on the
faceplate.
NOTE:
A DSL card may be replaced without disturbing the operation of other DSL
cards (i.e., you can remove and re-install a card without powering down the
chassis and disrupting service to the other cards). To remove a DSL card
from the chassis, unfasten the screws on the top and bottom of the faceplate.
Then, simply push the ejector handles outward and slide the card out.
When swapping the old DSL card with a new DSL card, it is important to note
that the HotWire 8800 DSLAM retains the Media Access Control (MAC)
address, also referred to as the physical address. This means that the new
DSL card will have the same MAC address as the old one. However, the new
card will have to be reconfigured.
Verifying the Installation
To verify the hardware installation, observe the front panel indicators. In normal
operation:
The POWER A LED and/or the POWER B LED are in the ON state (green).
— If you are using dual power sources, both Power LEDs must be ON.
— If you are using a single power source, the appropriate Power LED
(either Power A or Power B) must be ON.
The FAN ALM LED must be OFF.
Also check the SYSTEM LEDs on the MCC and DSL cards if you have not
done so already. The OK SYSTEM indicators on the cards must be in the ON
state (winking green).
If these status indicators fail to appear as described, see Chapter 4,
Troubleshooting,
for troubleshooting procedures. Also refer to Appendix A,
LEDs,
for a complete list of these indicators and their descriptions.
