26 CHAPTER 2: INSTALLING THE SWITCH
Choosing a Suitable
Site
The Switch is suited for use in an office environment where it can be
mounted in a standard 19-inch equipment rack, or free standing.
Alternatively, the Switch can be rack-mounted in a wiring closet or
equipment room. A rack-mounting kit, containing two mounting
brackets and four screws, is supplied with the Switch.
When deciding where to position the Switch, ensure that:
■
You are able to meet the configuration rules detailed in
“Configuration Rules for Fast Ethernet” on page 21.
■
The Switch is accessible and cables can be connected easily.
■
The switch is situated away from sources of conductive (electrical)
dust, for example, laser printers
■
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 and laser printers
■
Cabling is away from:
■
Sources of electrical noise such as radios, transmitters and
broadband amplifiers
■
Power lines and fluorescent lighting fixtures
■
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. We recommend that you provide a minimum of
25mm (1in.) clearance.
■
No more than four Switch units are placed on top of one another, if
the units are free standing.
■
If used in an office environment, the switch is positioned so that any
noise from the fan is not disruptive.
