Installing an analog port board

Complete the following procedure to install an analog port board in a Message Networking system. Use the D120JCT-LS 12-port analog port board diagram or the D41JCT-LS 4-port analog port board diagram as a guide when installing the new card.

Warning! Damage from electrostatic discharge is possible. See Protecting against ESD damage for more information.

To install an analog port board:

1. If the system is in service:
   1. Stop the voice system.
   2. Shut down the voice system.
2. If necessary, remove the incoming power.
3. For a rack-mount setup, remove the server from the cabinet if necessary:

   Caution: For safety purposes, get another person to assist you with moving the server.

   1. Prepare a clear area as a work surface for the server.
   2. Unplug all cables at the back of the server. Label all cables so you can easily reconnect them.
   3. Press the release clips on the rails to fully extend the rail.
   4. Lift the server off the rails and set the server on the work surface.
4. If necessary, remove the PC cover.
5. Remove the new card from its packaging and verify that the new card is configured properly.
6. If you are adding a card to the system, remove the slot faceplate retaining screw and then remove the slot faceplate.
7. Position the card in the correct slot:
   • If you are replacing an existing card, install the replacement card in the slot from which you removed the old card.
   • If you are adding a new card, install the card in the next available PCI slot (from right to left for an S3400-H or an S3210R or from bottom to top for an S3210)
8. Slide the card's edge connector into the slot and the card slot retainer bracket into the slot guide. Apply pressure to the top of the card only, until the edge connector is firmly seated. See Installing an analog port board.

Note: It is very important that you properly seat the card in the slot. If the card is not properly seated, the system will not recognize it.

9. Replace and tighten the slot retaining screw to secure the card.
10. If multiple analog port boards are installed, use the Computer Telephony (CT) bus cable to connect the port boards. To attach the bus cable.
    1. Position the CT bus cable so that the colored strip on the ribbon cable faces toward the ports at the back of the chassis.
    2. Attach the end connector on the bus cable to the CT bus edge connector at the top of the card in the highest numbered slot.
    3. Connect the next bus connector to the next port board, and so on.
    4. When finished, if the cable has extra connections or loose ribbon cable, tuck the cable so that it does not snag when you replace the cover.
11. If you are removing a card from an S3210R, replace the S3210R circuit card hold-down bracket. If you are removing a card from an S3400-H, replace the S3400-H circuit card hold-down bracket.
12. If you are installing a card into an S3210R or an S3210 server, locate the fastener for the analog port board in place, and then press the fastener down towards the card and snap it in place to secure the analog port board.
13. Replace the PC cover.
14. For a rack-mount setup, return the server to the cabinet:

    Caution: For safety purposes, get another person to assist you with moving the server.

    1. Push in the release lock, the front latch, to slide the server into the cabinet.
    2. Plug in all of the cables at the back of the server.
15. Plug the RJ-11 phone cables into the RJ-11 jacks on the card. Check the numbering on the board faceplate to verify that you are connecting the correct cord to the correct port.
16. Restore power to the system.
