Choosing a Suitable	The Switch is suited for use in an internal wiring closet, a network room,
Site	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 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).

If the Switch is installed in a 19-inch rack or closed assembly its local air temperature may be greater than room ambient temperature.
