To install and connect the DC power supply to the NetScreen-ISG 2000:
1.
Slide the power supply into one of the power compartments in the back of the 
system.
2.
Fasten the power supply to the system by tightening the corner screws into the

The DC power supply, ON/OFF switch, grounding screw, and terminal blocks are located 
on the faceplate of the power supply unit.
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.
Note: 
Whenever you deploy two power supplies to a NetScreen-ISG 2000, connect 
each to a different power source. Each power supply is intended to receive power 
from separate feeds.
Note: 
If there are multiple power supplies in the NetScreen-ISG 2000 and any of 
them are off, the Alarm LED on the management module glows red. This 
warning indicates that maximum system reliability requires all installed power 
supplies to be operational.
Warning: 
You must shut off current to the DC feed wires before connecting the wires to the 
power supplies. Also, make sure that the ON/OFF switch is in the off position.
