Connecting -48V DC Power Supplies

The GigaVUE Traffic Aggregator is available with 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

1.

Plug the DC power cable adapter into the DC power supply. For screw terminal DC power supply, use ring terminal. This is not applicable for GigaVUE‑TA400.

Note:  Terminal block supports 10AWG.

2.

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.
