A Hotwire 8774 TDM SDSL Termination Unit can be installed, removed, and
replaced from a the DSLAM chassis without disrupting service to the other cards
in the chassis.
Procedure
To install the unit:
1. Determine in which slot the unit will be installed. Verify that cards in adjacent
slots have been fastened.
2. Remove the filler plate from the installation slot and store for possible later
use.
3. Insert the unit into the DSLAM:
— For a Hotwire 8600 Series DSLAM chassis – Hold the unit horizontally,
with the component side facing up, and insert it into the left and right card
guides.
— For a Hotwire 8800 Series DSLAM chassis – Hold the unit vertically,
with the component side facing right, and insert it into the top and bottom
card guides.
4. Slide the unit into the slot until the power and network connectors seat firmly
in the mating connectors on the backplane.
CAUTION:
Do not force the unit into the slot. This can damage the backplane
connectors. If the card does not seat properly, remove the card and
reinstall it. If it still does not seat properly, call your service
representative.
The termination unit performs 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 begins to pulse once per second.
5. If the LED is not pulsing, refer to Messages and Troubleshooting in the User's
Guide.
6. Secure the unit by fastening the screws at each end of the faceplate.
