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:

Figure 18 Connecting -48V DC Power Cable Adapter
1.   Plug the DC power cable adapter into the DC power supply.

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.
Connect the positive source wire to the + RETURN (black) terminal using a straight blade screwdriver.
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.
