    Figure 3: Attaching the Mounting Brackets (2-post) To install the rack-mount brackets on the SCE 2000 chassis, complete the following steps: Before installing the SCE 2000 in the rack, you must first install a rack-mount bracket on each side of the front of the SCE 2000.
  • Page 9: Mount The System To The Rack

    Attach the Crossrail Supports to the Rack Figure 5: Attaching the Crossrails to the Rack Step 1 Align the crossrail supports with the side of the rack, parallel to the floor. Insert and tighten two screws to the front posts or mounting strips of the rack Step 2 Insert and tighten two screws to the Back posts of the rack.
  • Page 10 Step 3 Slide the SCE 2000 into the rack, pushing it back until the brackets (installed at the front of the SCE 2000) meet the mounting strips or posts on both sides of the rack. A rack with both front and back posts will have the crossrail supports installed. Slide the SCE 2000 onto these crossrails and push it all the way back.

  • Page 35: Step 10: Completing And Saving The Configuration

    Step 10: Completing and Saving the Configuration When you have completed the entire configuration, the system checks for errors. If errors are found, a warning message appears. When the configuration is error-free, you may apply and save it. To complete and save the configuration, complete the following steps: The system informs you that data collection is complete.
  • Page 36 Enter a full FTP path of the remote destination: Step 6 The system informs you that the configuration is complete. Committing configuration... Configuration completed successfully. Saving configuration... Writing general configuration file to temporary location... Backing-up general configuration file... Copy temporary file to final location... Done! This completes the procedures for initial configuration of the SCE 2000 platform.

    XAMPLE Following is an example of a configuration that was applied and saved to the startup configuration as well as to an FTP site. Although not demonstrated in this example, it is recommended that you always view the configuration before applying it. Data collection for the system configuration is completed.
  • Page 38 The SCE 2000 has two management ports, labeled Mng1 and Mng 2. Use the Mng 1 port. Plug the Ethernet cable provided (with attached RJ-45 connector) into the Mng 1 port on the front panel of the Step 1 SCE 2000. Connect the other end of the Ethernet cable into your management network.
  • Page 39: Cable The Line Ports

    Cable the Line Ports This section provides instructions for cabling the Fast Ethernet ports for both one and two SCE 2000 topologies, and for configuring Fast Ethernet (FE) interface parameters. In a topology utilizing two SCE 2000s (cascade), this includes the cascade ports as well as the line ports.
  • Page 40: Single Link: Inline Topology

    Single Link: Inline Topology In the inline topology, the SCE 2000 resides physically on the FE (Fast Ethernet) link between the subscribers, which are usually connected through either a BRAS (in DSL access), a PDSN (in wireless access), a CMTS (in the Cable access), or a switch or router aggregator (in other topologies), and the network, where the SCE 2000 usually connects to a router or layer 3 switch network element.
  • Page 41 Figure 15: Cabling Diagram for Single SCE Platform Single Link Receive-only Topology The single link receive-only topology cabling is similar to that for single link inline, in that either the first FE link (FE-1 SUB/NET) of the SCE 2000 or the second FE link (FE-2 SUB/NET) can be used, as illustrated in the diagram above. However, in the receive-only topology, the SCE 2000 is connected to the external switch rather than being directly connected to the FE link.
  • Page 42 The following diagram illustrates the connections for dual links, with a single SCE 2000 deployed for both inline and receive-only topologies. For inline topologies, the SCE 2000 is directly connected to the two FE links, using the FE-1 and FE-2 ports as described above.
  • Page 43 Inline topologies can both Receive and Transmit to the SCE 2000. Cascade ports always require both Receive and Transmit to be connected. The following diagram illustrates the connections for a dual link, two SCE 2000 inline topology For inline topologies, the SCE 2000 is directly connected to the two FE links, using the FE-1 ports on the two SCE 2000s, while the FE-2 ports on both units are used as the cascade ports, as described above.
  • Page 44 Figure 17: Cabling Diagram: Dual Link Inline Topology Two Cascaded SCE Platforms Connect the FE Line Interface Ports Figure 18: Cabling the FE Interface Refer to Cabling Diagrams (on page 39) to find the appropriate cabling diagram for the topology of your system for the specific connections required.
  • Page 45: Completing The Installation

    Completing the Installation This section discusses how to verify link connectivity and how to install a Service Control application. Examining the Link LEDs The Link LED must be green in order to verify that an active connection exists. The Active LED (if flashing green) indicates that traffic is being received and/or transmitted by the SCE 2000. In receive-only topologies, the Active LED indicates that packets are being received.

  • Page 55: Identifying Startup Problems

    Identifying Startup Problems Startup problems are commonly due to the source power or to a poor cable connection. This section contains a detailed description of the normal startup sequence and describes the steps to take if the system does not perform that sequence as expected.
