10 User’s Guide
GENERAL INSTALLATION GUIDELINES
Observing the following precautions can prevent injuries, equipment failures and
shutdowns.
•Never assume that the power supply is disconnected from a power source.
Always check first.
•Room temperature might not be sufficient to keep equipment at acceptable
temperatures without an additional circulation system. Ensure that the room in
which you operate the device has adequate air circulation.
•Do not work alone if potentially hazardous conditions exist.
•Look carefully for possible hazards in your work area, such as moist floors,
ungrounded power extension cables, frayed power cords, and missing safety
grounds.
PERFORMING EQUIPMENT-RACK INSTALLATION
Although you can install a NetScreen-200 Series device on a desktop, it is advisable to
install the device in an equipment rack if possible.
Equipment Rack Installation Guidelines
The location of the chassis and the layout of your equipment rack or wiring room are
crucial for proper system operation.
Use the following guidelines while configuring your equipment rack.
•Enclosed racks must have adequate ventilation. An enclosed rack should have
louvered sides and a fan to provide cooling air.
•When mounting a chassis in an open rack, ensure that the rack frame does not
block the intake or exhaust ports. If you install the chassis on slides, check the
position of the chassis when it is seated all the way into the rack.
•In an enclosed rack with a ventilation fan in the top, equipment higher in the
rack can draw heat from the lower devices. Always provide adequate ventilation
for equipment at the bottom of the rack.
•Baffles can isolate exhaust air from intake air. The best placement of the baffles
depends on the airflow patterns in the rack.
You can mount the device in a standard 19-inch equipment rack. Rack mounting requires
the following tools:
•1 Phillips-head screwdriver
•Rack-compatible screws
•The supplied front-mount brackets
•The supplied mid-mount brackets
Note: To prevent abuse and intrusion by unauthorized personnel, it is extremely important
to install the NetScreen device in a locked-room environment.

Connecting the Power
NetScreen-200 Series 11

WIRING ADC POWER SUPPLY
The DC power supply, ON/OFF switch, grounding screw, and terminal blocks, are located
in the back of the chassis 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 then tighten the hex nut securely.
3. Connect the other end of the grounding lug wire to a grounding point at your
site.
NetScreen-200 Series devices can operate on one or two feeds. To connect DC power feeds
to the terminal blocks:
1. Strip the ends of the power cables.
2. Loosen the three screws in the top of the block. (These are captive screws, which
you cannot completely remove.)
3. Insert the 48V DC power feed wires into the two outside receptacles of the
terminal block.
4. Insert the 0V DC feed wires into the center receptacle.
5. Tighten the screws over the receptacles.
Warning: You must shut off the current to the DC feed wires before connecting the wires to
