Model 3811Plus Installation

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 381 1 Plus modem into the carrier, perform the following steps.

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.

3. Rotate the circuit pack lock(s) into the closed position, and tighten the screw.

4. If the carrier is connected to power, the Power LED on the faceplate of the
3811Plus lights up. After several seconds the modem completes its power-up
self-test in which all faceplate LEDs light up.

If the modem fails, or an alarm condition exists, the Alrm LED on the faceplate
lights up or flashes. It may be possible to run a diagnostic self-test from the SDCP.
See Test Branch in the COMSPHERE 3800Plus Modems User’s Guide.

Return to the rear of the carrier and tighten the rear connector plate.

5. Connect an RS-232D DTE cable to the top connector of the rear connector plate.
(The bottom connector is unused.)

6. Connect the other end of the cable to your DTE.
