NSTALLATION
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.
Important:
Although you can place the device on a desktop for operation, it is not
advisable to deploy a NetScreen-ISG 2000 in this manner. The best deployment technique
is equipment rack mounting, described below.
Warning:
To prevent abuse and intrusion by unauthorized personnel, install the
NetScreen-ISG 2000 in a locked-room environment.

The NetScreen-ISG 2000 comes with accessories for mounting the device in a standard
19-inch equipment rack.
Equipment Rack Installation Guidelines
The location of the chassis, the layout of the equipment rack, and the security of your
wiring room are crucial for proper system operation.
Use the following guidelines while configuring your equipment rack.
•
Enclosed racks must have adequate ventilation. Such ventilation requires
louvered sides and a fan to provide cooling air.
•
When mounting a chassis in an open rack, be sure 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.
