24CHAPTER 2: INSTALLING THE SWITCH

Choosing a Suitable The Switch is suited for use in an office environment where it can be

Sitewall-mounted, 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 wall-mounting/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 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.

Rack-mounting The Switch is 1.5U 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.

1Place the Switch the right way up on a hard flat surface, with the front facing towards you.

2Locate a mounting bracket over the mounting holes on one side of the Switch, as shown in Figure 7.
