3811Plus Installation

The installation of a 3811Plus varies slightly if an SDCP is installed on the front of the carrier. To install a 3811Plus modem into the carrier without an SDCP, perform the following steps:

CAUTION

If you remove the 3811Plus from the carrier, always use a ground strap when handling the modem. Always store the 3811Plus in an antistatic bag when it is removed from the carrier.

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.

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 (see Figure 3-2).

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. The faceplate latch automatically closes as you push the modem into the carrier. To lock the modem into the carrier, press the faceplate latch until a click is heard.

3.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.

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