T1 Modem Bank
72
Perform the following steps to install a modem card:
1. Before installing an additional modem card into an empty slot, you must remove the faceplate covering the slot.
Loosen the captive screws from the faceplate using a flathead screwdriver and lift off the faceplate.
2. To install the modem card in an empty modem slot, turn the modem card so the card edge faces the back plane
and the LEDs face outward, toward the front of the chassis. The slot in the chassis contains a card guide; RFI
fingers on the card should be on the left side of the card guide. Slide the modem card into the slot and push
firmly until the card seats with the back plane receptacle.
3. Finger tighten the two captive fasteners on the modem card. Note that each fastener must be properly aligned;
the fasteners could be stripped if they are not correctly threaded into the receptacle. To better secure the modem
card, tighten the two captive fasteners using the flathead screwdriver.
4. After installation, the power LED (marked PWR) on the modem card will be lit.
