  • Page 61: Wiring The -48 Vdc Power Supply

    Appendix B Wiring the –48 VDC Power Supply If your NSG has the optional –48 VDC power supply, follow these steps to wire the power supply. Getting Started Before you begin wiring the –48 VDC power supply, make sure that you provide the necessary overcurrent protection, wires, and power connector.

  • Page 62: Overcurrent Protection

    The NSG is connected to the DC power source using three wires: –Vin +Vin Although Harmonic provides the power input connector with the NSG device, you must supply the wires. The wires to be used must comply with the following specifications:...

  • Page 63: Power Connector

    This connector is made by WAGO, model number 231-103/037-000. Use only the original connector for connecting the NSG to the DC power source. Contact Harmonic Technical Support if you want to use any other type of connector. The following figure shows the connector and its strain relief housing:...

    Gigabit is used. Cascading with IP switching allows to optimize the GbE bandwidth by using three NSG 9116 units that are fed by two GbE inputs. Cascading Single Channels Cascading single channels is recommended when using two NSG 9112 units.

  • Page 68: Cascading Redundant Channels

    60 Cascading APPENDIX C 5. In the web client configure the appropriate GbE channel. The following figure illustrates the cascaded connections. Cascading Redundant Channels The NSG family also supports GbE channel redundancy for cascaded NSG devices. Cascading redundant channels is recommended when using three NSG 9108 units.
  • Page 69 Advanced Fiber Optic Connections Cascading The following figure shows the connections for cascaded NSGs with redundancy.

  • Page 70: Cascading With Ip Switching

    To fully utilize the GbE feed and the capacity of the NSG, it is best to use 3xNSG 9116 units cascaded with IP switching. Chain two different NSG 9116 units to another NSG 9116 unit. Each of the two units receives a different GbE input stream and draws the services intended for it. Each unit passes on the traffic to a different GbE port of a third NSG unit so a total of one GbE is used.
