  • Page 21: Chapter 2 Nc4000 Node Overview

    The type of transceiver depends on the return RF frequency and the optical reach requirements to the next node or headend (or hub). The NC4000 requires one or more transceivers, where the number of transceivers depends on the return path segmentation or redundancy requirements for additional Ethernet services.

  • Page 22: Mechanical Features

    RF distribution network. Mechanical Features The NC4000 Node is packaged in an aluminum housing that protects the electronics from weather and dissipates internally generated heat (Figure 2.2). The housing is divided into two halves, the housing base and housing lid.

  • Page 23: Rf And Weather Sealed Enclosure

    (Figure 2.3). The housing lid incorporates a woven-wire gasket to provide RF shielding and grounding. Both gaskets must be in place and in good condition to ensure reliable operation. Figure 2.3 RF and Weather Seals TM 87-10923 Rev E NC4000 Node Overview...

  • Page 24: Cable Entry

    P6 are for RF and AC input power, and ports P2 and P5 are for AC only. See 4.4 RF Coaxial Cable Connections on page 4-6 and 4.5 Power Cable Connections on page 4-8 for coaxial cable connection procedures. (P2 and P5 can also carry RF—contact ARRIS Field Services for information about routing RF through P2 and P5.) There are two fiber optic cable entry ports on the lid.

  • Page 25: Mounting Options

    The RF amplifier tray sends forward path RF to subscribers, and receives return path RF from subscribers, through four coaxial ports (P1, P3, P4, and P6). The NC4000 node utilizes the OA4324HG ultra high level RF output amplifier with GaN hybrids. The RF amplifier tray is easily removed for access to the coaxial cable connectors under the tray (see 4.3 Removing and Replacing...

    RF connections between the motherboard and RF amplifier are made through coaxial cables. Figure 2.6 Lid Motherboard – LM4002 NC4000 1 GHz Node TM 87-10923 Rev E...

  • Page 27: Power Supplies

    2.3.3 Power Supplies The NC4000 can be powered from one or two power supplies (Figure 2.7). One power supply provides sufficient DC power to run the RF amplifier and plug-in modules. Two power supplies provide redundancy if one power supply fails. The power supply requires 44 to 95 VAC input, and provides +3.3, +5, +12, and +24 VDC outputs.

  • Page 28: Return Path Transceivers

    A second transceiver would only be required for redundancy. Table 2.2 lists the DT4xxx transceivers available for the NC4000. A transceiver is required in slot A of the lid motherboard for node monitoring/management. A second transceiver (when applicable) goes in slot F.

It supports two analog return signals and can be used to transport either a single (1-fer) or two separate returns (2-fer) operating in various bandwidths. The operating bandwidth and number of returns are user selectable, each model number supporting two bandwidth ranges (Table 2.2).

  • Page 32 There are applications where local network conditions demand adding remote security cameras, channels or groups to a specific area or building serviced by an NC4000 node. In these special applications the NC4000 Optical Node provides physical connections to externally manipulate normal CATV signals through the use of couplers, band-stop or band-pass filters to accomplish the signal addition at a local level.

  • Page 33: Chapter 3 Configuring Nc4000 Nodes

    Shut down or disconnect external AC power to the node before removing or replacing the RF amplifier tray in the base housing. Note While the NC4000 nodes are ruggedized units designed to operate outdoors in cable networks, they are not indestructible. Do not drop nodes―keep nodes in their shipping boxes when they are not on the bench.
  • Page 34 To install an RF amplifier tray: If you are going to test the configured NC4000, make the applicable RF and power connections to the base housing (ports P1 through P6) before installing the RF amplifier. Ensure that all six seizure nuts are torqued to 6.25 foot-pounds (8.5 newton-meters). See 4.4 RF Coaxial Cable Connections on page 4-6 through 4.6 Fiber Optic Cable Connections on...

  • Page 35: Power Supply Installation

    Install the applicable fuse(s) to route AC power to the power supply(s). See 3.2.1 AC Power Distribution Fuses on page 3-4 for details. With AC power applied to the NC4000, measure the voltages at the test points on the power supply.

  • Page 36: Ac Power Distribution Fuses

    3.2.1 AC Power Distribution Fuses AC power comes into an NC4000 through one of the six ports, and is distributed to the power supply(s) through 90 V, 15 A, automotive blade fuses. Figure 3.3 shows an example of AC power coming into P6, and routed to the power supply through the P6 fuse.
  • Page 37 Figure 3.5 shows how AC power can be routed to two power supplies from two independent sources (through P3 and P6). This “split bus” configuration provides an additional level of redundancy. That is, the NC4000 will remain powered up even if one power supply fails, or one AC input to the node fails.
  • Page 38 Figure 3.6 shows how AC power can be routed out of an NC4000 to another device (or another NC4000) through another port. In this example, AC power comes in through port P6, is routed to the power supplies through the P6 and AC thru fuses, and is routed out to another device (connected to port P3) through the P3 fuse.

    Forward Path Configuration Note Where specific procedures (such as segmentation) are applicable to both Chapter 3, Configuring NC4000 Nodes and Chapter 4, Installing NC4000 Nodes, you are referred to Chapter 4, where the context is installing the node in the network.

  • Page 40: Automatic Forward Path Rf Switching

    3.4.1 Automatic Forward Path RF Switching NC4000 nodes can be configured for primary/redundant forward path RF switching. This is an optional feature, and requires the installation of an FS4021 (AR4x03G only) or FS4121 (AR4x14G and AR4x24G) switch on the lid motherboard.

    3.5.1 Return Path Segmentation Return path segmentation refers to the number of return RF streams coming into the NC4000. The NC4000 can support one or two return streams with a single DT4250. Configure return segmentation per 4.8.2.1 Return Path Segmentation—OA4324HG RF Amplifiers on page 4-18.

  • Page 46: Pedestal Or Surface Mounting

    These 5/16 x 18 x 3/4 holes are separated by 13.5 inches center-to-center and can be used for pedestal or surface mounting. Remove the mounting plate (not part of the NC4000) from the inside of the pedestal if possible. Remove both strand clamp bolts and strand clamps from the housing base. You will use these bolts to fasten the base to the pedestal or surface mount fixture.

  • Page 47: Wall Mounting

    Wall Mounting To mount the NC4000 to a wall using the HB4003 mounting brackets (available from ARRIS): Place the NC4000 on a stable work surface with the base facing up and the RF connectors at the bottom (see Figure 4.3).

  • Page 48: Grounding

    – For a pedestal or surface mounted NC4000, remove one of the two strand mount brackets, and install the grounding stud in the threaded hole. Using an 11/16-inch wrench, loosen the top nut and insert the grounding cable. (You may need to remove the nut to insert the cable.)

  • Page 49: Preconfiguration And Testing

    NC4000 Preconfiguration and Testing NC4000 nodes should be preconfigured and tested in a shop/lab environment before being installed in the network. The objective is to have fully functional and tested nodes that requires only minimal adjustments during installation. See Chapter 3, Configuring NC4000 Nodes for shop/lab procedures.

  • Page 50: Rf Coaxial Cable Connections

    Figure 4.6 Port Locations Before opening the NC4000 housing, verify that all RF coaxial cables (up to four) are available at the node location. Double-check cable labeling to ensure that cables get connected to the correct ports. Inspect the RF cable connectors (KS type) and verify the length of the stinger (Figure 4.7). If the connectors are not installed, install them now.
  • Page 51 Repeat Step 8 and Step 9 for all remaining RF ports (not including ports 2 and 5). For any unused RF ports, install a 75 Ohm line terminator on the port (not including ports 2 and 5). TM 87-10923 Rev E Installing NC4000 Nodes...
