1. At the back of the carrier, install the connector plates (Figure 5). Make sure the plate(s) use the same slot
positions as that intended for the modem.
Loosely fasten the plate(s). 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 1–15 (Figure 6).
Slide the modem into the slot, aligning the modem with the connector plates, 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 ON, the Power LED on the faceplate of the Model 3921Plus lights. After several seconds
the modem completes its power-up self-test, in which all faceplate LEDs light.
Return to the back of the carrier and tighten the connector plate(s).
