| UNIT 3: INSTALLATION - LESSON 2: INSTALLING OPTIONAL SERVICE CARDS Now that the front cover is open the optional service cards can be installed. Installing a KX-TAW84893 on a KX-TAW84880 The first card that we will install is the KX-TAW84880 4-Port Analog Trunk Card (LCOT4). Adding this card will allow 4 additional loop start CO lines to be installed, expanding the system to its maximum capacity of 8 CO lines. Let’s assume that our system will receive Caller-ID information on lines 4 through 8 but not on lines 1 though 4. This requires a KX-TAW84893 4-Port Caller ID Card (CID4) to be installed on the expansion LCOT4 card. (If Caller-ID were to be received on all lines, an additional CID4 card would need to be installed onto the preinstalled LCOT4 card as well.) Note: If any KX-TAW84893 Caller ID cards are going to be installed, it is easier to install them prior to installing any expansion cards. Remove the KX-TAW84880 and KX-TAW84893 cards from their cartons and place them on a flat work surface. Locate the 2 notches on the KX-TAW84880 card just above the arrows on the plastic card frame. Holding the KX-TAW84893 by the edge of the card insert the plastic tabs on the front of the card into the notches of the KX-TAW84880 card. Press down lightly on the opposite end of the KX-TAW84893 card to seat the card in place.
