Warning: You must shut off the electric current to the DC feed wires before connecting the wires to the power supplies. Also, make sure that the power switch is in the off position.

To connect the DC power supply to a grounding point at your site:

1.Remove the hex nut on the grounding screw.

2.Place the ground lug on the screw and tighten the hex nut securely.

3.Connect the other end of the grounding lug wire to a grounding point at your site.

To connect DC power feeds to the terminal blocks:

1.Loosen the retaining screws on each terminal block.

2.Insert the 0V DC (positive voltage) return wire into the center COM connector and the -48V DC power feed wire into either the left or right connector.

3.Fasten the screws over the connectors.

4.Turn the power switches on.

Note: If there are multiple power supplies in the NetScreen-5000 Series system and any of them are off, then the Alarm LED on the Management Module glows red. This alarm indicates that maximum system stability requires all installed power supplies to be operational.
