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).
