Digi 90031300 manual Component Removal and Installation

The line card is located on the left as you face the front of the chassis. It is accessed from the front of the chassis. A power indicator LED and a T1 jack are part of the line card faceplate. Follow this procedure to replace the line card:

1.Label, then remove the T1 line.

2.There are two captive fasteners that secure the line card to the chassis. To remove the malfunctioning line card, use a flathead screwdriver to loosen the captive fasteners on the malfunctioning line card. Pull the ejector levers, then slide the malfunctioning line card out of the chassis.

3.To install the replacement line card in the slot, turn the card so the card edge faces the back plane, and the LED and RJ48 connectors face outward, toward the front of the chassis. The slot in the chassis contains a card guide; the card should be inserted so the RFI fingers are on the left of the card guide. Slide the new card into the slot and push in firmly until the card seats with the back plane receptacle.

4.Finger-tighten the two captive fasteners on the line card. Each fastener must be properly aligned; it could be stripped if not correctly threaded into the receptacle. To better secure the line card, tighten the two captive fasteners using the screwdriver.
