Installing a Mini-DSS Unit
The Model 8416 Mini-DSS Unit provides 16 additional user-programmable buttons and
connects directly to the Model 8660 IP endpoints. Mini-DSS Units are physically attached to a
special cable pin connector. Because the Mini-DSS Units draw power from the endpoint,
external AC transformers are not required. Mini-DSS Units are optional equipment.
Unpack and inspect the Mini-DSS Unit. Install each Mini-DSS Unit as outlined below. For
diagrams of the installation, see Figure 5-71 on page 5-204 and Figure 5-72 on page 5-204.
To install a Mini-DSS unit:
1. Lift and remove the original faceplate using the notch on the faceplate edge of the
endpoint. The original faceplate can be returned to Mitel for recycling.
2. Remove the original endpoint facemats and set them aside for later use.
3. Turn the endpoint over so that the Mini-DSS access panels located on the bottom of the
endpoint are accessible. The recess beneath the top access panel houses the pin
connector for the Mini-DSS cable.
4. Remove the screws from the access panels and set them aside for later use.
5. Remove the access panels from the endpoint. The endpoint access panels can be
returned to Mitel for recycling.
6. Turn the Mini-DSS over and pull a section of ribbon cable measuring 1¾
in. (4.5 cm)
from the unit.
7. Plug the cable from the Mini-DSS unit into the pin connector on the endpoint.
8. Guide the “arms” of the Mini-DSS unit into the access panel slots.
9. Secure the Mini-DSS unit to the endpoint by replacing and tightening the screws
removed from the access panels in step 5.
10. Turn the endpoint, and attached Mini-DSS, over. Replace the original facemats on the
and place the Mini-DSS facemats on the Mini-DSS unit.
11. Snap the Mini-DSS faceplate into place covering the facemats.
NOTE
Avoid removing more cable than the recommended 1¾ in. (4.5 cm). The
excess cable may be difficult to return to inside the Mini-DSS unit.
