Choosing a Suitable Site
The Switch is suited for use on a desktop, either free standing or
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.
■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.
