The COMSPHERE 3000 Series Carrier has 17 slots which can hold up to 16 modems and one SDU. The SDU is required when the modems in the carrier are controlled by an NMS, or when multiple carriers in a cabinet configuration are to be controlled by a single SDCP. The SDCP of the COMSPHERE 3000 Series Carrier is the user interface to the 3811Plus modem. A single SDCP can control modems in up to eight carriers.
To install a 3811Plus modem into the carrier, perform the following steps.
Procedure
1.At the rear of the carrier, install the rear connector plate. Make sure the plate uses the same slot position as that intended for the modem.

Loosely fasten the plate. This allows for slight adjustments later when installing the modem.
CAUTION
Always use a ground strap when handling a modem. Always store a 3811Plus modem in an antistatic bag when it is removed from the carrier.
2.At the front of the carrier, hold the modem vertically, with the latch on its faceplate in the open position, and insert it into the top and bottom card guides of one of the slots numbered 1±16.
Slide the modem into the slot, aligning the modem with the rear connector plate, until the backplane connector and DTE connector seat firmly into the back of the carrier. To lock the modem into the carrier, press the faceplate latch until a click is heard.
