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 NetScreen-5000 Series 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.

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 included rear slide kit (for the rear and front mount method) on the
NetScreen-5200
• Front-mount brackets
Important: Although you can place the NetScreen-5000 Series on a desktop for operation,
NetScreen does not recommend deploying it in this manner.
Warning: To prevent abuse and intrusion by unauthorized personnel, it is extremely
important to install the NetScreen device in a locked-room environment.
