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.
power lines and fluorescent lighting fixtures.
■
The Switch is accessible and cables can be connected easily.
■
Water or moisture cannot enter the case of the Switch.
■
Air flow is not restricted around the Switch or through the vents in the
■
side of the Switch. 3Com recommends that you provide a minimum of
25 mm (1 in.) clearance.
Air temperature around the Switch does not exceed 40 °C (104
■
F).
