When deciding where to position the switch, ensure that:
Cabling is located away from:
1) Sources of electrical noise such as radios, transmitters and
broadband amplifiers.
2) 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.
The air is as free from dust as possible.
The switch is situated away from sources of conductive
(electrical) dust, for example laser printers.
The unit is installed in a clean, air conditioned environment.
The AC supply used by the switch is separate to that used by
units that generate high levels of AC noise, for example air
conditioning units.
No more than four switch units are placed on top of one another,
if the units are free-standing.
Rack Mounting
The Switch is 1U high and will fit in most standard 19-inch racks.
