Connecting -48V DC Power Supplies

The GigaVUE Traffic Aggregator has two DC power supplies instead of the standard AC power supply. This section provides instructions for connecting a -48V DC power source to the DC power supplies.

To connect a -48V DC input to the DC power supply:

1 Connecting -48V DC Power Cable Adapter

To connect a -48V DC input to the DC power supply,

1.   Plug the DC power cable adapter into the DC power supply. For screw terminal DC power supply, use ring terminal. This does not apply to GigaVUE‑TA400.

Note:  Terminal block supports 10AWG.

2. (Optional) If PSM grounding is required, connect earth ground to the SAFETY GROUND (green/yellow) terminal using a straight blade screwdriver.
3. Connect the positive and negative power wires to the appropriate terminals using a straight-blade screwdriver.
o   Connect the positive source wire to the + RETURN (black) terminal using a straight blade screwdriver.
o   Connect the -48V source wire to the -48V (blue) terminal using a straight blade screwdriver.

Important: The leads to the DC power supply modules on the GigaVUE TA Series node should attach from the side of the chassis away from the terminal block. Run the wires to avoid obstructing airflow for the adjacent fans.

4. Repeat Step 1 through Step 3 for the other power supply modules.

Regional Compliance (Australia and New Zealand Standards)

This section provides guidance to ensure that the DC power cable complies with AS/NZS 5000 and AS/NZS 3015.

Note:  For compliance with ANZ standards, the DC cable can be ordered using part number PCD-00051. PCD-00051 is supported on GigaVUE‑TA25, GigaVUE‑TA200, GigaVUE‑HC1, and GigaVUE‑HC1-Plus (with D-SUB DC connector). This requirement is optional and applicable only within the Australia/New Zealand region.

To connect a -48V DC input to the DC power supply:

Establishing a reliable -48V DC input connection to the power supply involves connector assembly details, cable specifications, and insulation features for optimal performance.

  1. D-sub power cable connector assembly featuring a 3v3 type socket, contacts and backshell.

  2. The table below outlines the colors and specifications of the negative cable, positive cable, and ground cables.

     

    Cables Color Requirements
    - 48V cable Blue

    Insulation: PVC

    Conductor: 10AWG, 6mm2, 30A
    + Return Cable Red

    Insulation: PVC

    Conductor: 10AWG, 6mm2, 30A
    Safety ground cable Green, Yellow

    Insulation: PVC,

    Conductor: 10AWG, 6mm2, 30A

  3. The cable features an outer sheath made of black PVC for enhanced durability and insulation. The cable measures 3000 mm, with a tolerance of ± 50 mm.

Note:  Insulation material throughout the length of the cable must be rated for 105° C temperature.
