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-on 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 blinking 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 tightening the top and bottom screws on the faceplate
while applying slight pressure to the left to insure a good seal. This is required
to maintain proper gasket pressure on the faceplate.
NOTE:
If a new DSL card is not installed in this slot, a gasketed, single filler plate must
be installed to provide shielding and proper air flow.
