24 C HAPTER 2: I NSTALLING THE S WITCH
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 20 .
■
The Switch is accessible and cables can be connected easily.
■
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.
Rack-mounting The Switch is 1U high and fits in most standard 19-inch racks.
CAUTION: Disconnect all cables from the Switch before continuing.
Remove all self adhesive pads from the underside of the Switch if they
have been fitted.
1 Place the Switch the right way up on a hard flat surface, with the front
facing towards you.
2 Locate a mounting bracket over the mounting holes on one side of the
Switch, as shown in Figure 7 .
