2.3 Installing the Hardware

This section presents the procedures for installing the TX 3220C board in your system.

2.3.1 Installing the TX 3220C Board

To install a TX 3220C board in your system:

  1. Turn off the computer and disconnect it from the AC power source.

    

  2. Choose a chassis slot in which to place the TX 3220C board. Remove the faceplate from the chassis slot.
    

    

  3. Verify that the chassis slot has the appropriate keying:
    

      

    • Strawberry red key in P4

      

      

    • Brilliant blue key in P1

      

      

    • Slot keying for TNV1 levels in both the front and rear chassis

      

      
The keys in the backplane must have the same colors as the keys in the J1 and the J4 connectors of the TX 3220C board. Refer to Figure 4.
      
 

      


      


      WARNING:
      

      

      


      Only qualified personnel can install keying. This personnel must be familiar with the CompactPCI Computer Telephony Specification PICMG 2.5, R1.0 document.
      


      NMS is not responsible if you install a TX 3220C board and chassis keying has not been properly installed.
      

      

      


      


      

      

      

      


Note:  The TX 3220C board has been keyed prior to shipment.

For more information about keying, refer to Section 2.3.2, Keying Information.
      



      Figure 4.	 Keying
      

      

    • Slide the TX 3220C board into the front of the chassis, ensuring the board edges are properly seated in the guide rails.
      

      

    • Seat the board into the backplane by rotating the top and bottom handles.
      

      

    • Note the slot number of the TX 3220C board.
      

      

    • Secure the board to the chassis with the screws on the upper and lower handles.
      

      

    • Remove the rear faceplate.
      

      

    • If not keyed, key the rear panel I/O transition board with the same TNV1 keying as the front I/O board. Refer to the table in Section 2.3.2 for the proper TNV1 key positions for the TX 3220C board.
      

      

    • Slide the rear panel I/O transition board into the corresponding slot at the rear of the chassis.
      

      
 

      


      


      WARNING:
      

      

      


      Some rear panel I/O transition boards do not contain an alignment mechanism to use when inserting the board. Use caution when inserting the board into the backplane mating connector.
      

      

      


      


      

      

      

      

    • Seat the rear panel I/O transition board by rotating the handles.
      

      

    • Secure the board to the chassis with the screws on the upper and lower handles. Refer to Figure 5 for a view of how the TX 3220C board and the rear panel I/O transition board sit in the chassis.
      

      

    • Connect the computer to its AC power source.
      

      

    • If you have additional TX 3220C boards to install, repeat steps 1-13. When you have installed all of your TX 3220C boards, you must restart the computer.

    2.3.2	 Keying Information
    

    


    Safety requirements dictate that the chassis slot in which you will install a TX 3220C board must be properly keyed. Keying refers to the mechanical interlocks which, if not correct, will stop a board from insertion.
    

 

    


    


    WARNING:
    

    

    


    Only qualified personnel can install keying.
    


    NMS is not responsible if you install a TX 3220C board and chassis keying has not been properly installed.
    

    

    


    


    

    

    

    



    Adhere to the following keying requirements as specified in the CompactPCI Computer Telephony Specification PICMG 2.5 R1.0:
    

    

    The top and bottom handles are keyed for safety. Refer to the CompactPCI Computer Telephony Specification PICMG 2.5 R1.0 and to the IEEE 1101.10 for specific keying information.
    


    Chambers A, D, E, and F are defined by Backplane Wiring and Network Signaling Levels. Chambers B and C are user-specific. The keying for the TX 3220C board is as follows:

    WARNING:
    

    

    


    Important Safety Notes for Telephony Connections:
    

·	 Installation of this board and associated telephone wiring is to be performed only by competent technical personnel.
    

·	 Make sure the PC chassis is grounded through the AC power cord or by other means before connecting the telephone line.
    

·	 If your system requires an external power supply, make sure it is grounded through the AC power cord or by other means.
    

·	 Never install telephone wiring during a lightning storm.
    

·	 Never install telephone jacks in wet locations.
    

·	 Telephone companies provide primary lightning protection for their telephone lines. However, if a site connects to private lines that leave the building, make sure that external protection is provided.
    

    

    


    


    

    

    


    


    TX 3220C boards come with two RJ-48C connectors. Figure 6 shows the connectors on the rear panel I/O transition board used in conjunction with the TX 3220C T1/E1 board:

    Each of the RJ-48C connectors has the pinouts shown in Figure 7:

    2.5	 Ethernet Connectivity
    

    


    The 10/100Base-T Ethernet connector provides the TX 3220C board with an Ethernet connection supporting autonegotiation for 100Base-T full duplex/half duplex and 10Base-T full duplex/half duplex transmission.
    


    Each rear I/O transition board has a RJ-45 connector for Ethernet connectivity, as shown in Figure 8:
    




    Figure 8.	 10/100Base-T Connector on the Rear Panel I/O Transition Board
    

    

    The RJ-45 connector has the pinouts shown in Figure 9:

    2.5.1	 Connecting the TX 3220C Boards for SS7 Redundancy
    

    


    The TX 3220C board supports the redundancy feature available with the Signaling System 7 (SS7) software. The redundancy feature enables a system to detect and recover from the failure of signaling links on a TX SS7 board, the failure of a signaling node, or the failure of the TX SS7 board itself.
    


    Each pair of TX 3220C boards is connected via a private 10/100Base-T Ethernet link. No other boards or devices may be connected to this private Ethernet link.
    


    Figure 10 shows how to setup two TX 3220C boards based on the a dual-node redundant signaling server model in which the boards are located in two separate chassis for board-level and system-level redundancy.
    




    Figure 10.	 Dual Node Redundant Signaling Server
    

    

    Figure 11 illustrates how to setup two TX 3220C boards based on the single-node signaling server in which the boards are located in the same chassis for board-level redundancy.
