Choosing a Suitable
Site
The Switch 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.
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 temperature 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 flow around the Switch does not exceed 40 °C (104
°
F).
