Choosing a Suitable	The Switch is suited for use on a desktop, either free standing or
Site	mounted in a standard 19-inch equipment rack. Alternatively, the Switch
	can be mounted in a wiring closet or equipment room, as an aggregator
	for other Hubs and Switches. A rack-mounting kit containing two
	mounting brackets is supplied with the Switch.

CAUTION: Ensure that the ventilation holes are not obstructed.

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 25mm (1in.) clearance.
