Chapter 2 Installing the Device

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.

Note: To prevent abuse and intrusion by unauthorized personnel, it is extremely important to install the NetScreen device in a locked-room environment.

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
