Installing the
Switch
The following sections describe how to site and install your Switch.
Following Safety
Information
Before installing or removing any components from the Switch or
carrying out any maintenance procedures, you must read the safety
information Appendix A of this guide.
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 six 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 26.
■
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 objects are placed on top of the unit.
■
No more than four Switch units are placed on top of one another, if
the units are free standing.
Rack-mounting
The Switch is 1.5U high and fits in most standard 19-inch racks.
