Choosing a Suitable
Site

The Switch 3870 is suited for use in an internal wiring closet, a network
room, or telecommunications room, where it can be mounted in a
standard 19-inch equipment rack, or free-standing.

CAUTION: Ensure that the ventilation holes are not obstructed.

To ensure this product provides optimum performance, high speed fans
are used to provide ventilation. These fans have a high audible output
while running at full speed. The Switch 3870 is designed to reduce the
fan speed shortly after power on (if thermal conditions allow) which will
also reduce the fan noise generated.

When deciding where to position the Switch, ensure that:

Cabling is located away from:

sources of electrical noise such as radios, transmitters and
broadband amplifiers.
