Following Safety Information
Before installing or removing any components from
the Switch, or carrying out any maintenance proce-
dures, you must read the safety information pro-
vided in
Appendix A of this guide.
Positioning the Switch 1000
The Switch is suited for use in the office where it
can be wall-mounted, mounted in a standard
19-inch equipment rack, or free standing. Alterna-
tively, the unit can be rack-mounted in a wiring
closet or equipment room. A wall-mounting /
rack-mounting kit, containing two mounting brack-
ets and six screws, is supplied with the Switch.
When deciding where to position the unit, ensure
that:
■
You are able to meet the configuration rules
detailed in the following section.
■
The unit is accessible and cables can be con-
nected 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
unit.
■
Air-flow around the unit and through the vents in
the side of the case is not restricted. We recom-
mend that you provide a minimum 25mm (1in.)
clearance.
■
No objects are placed on top of the unit.
■
Units are not stacked more than four high if
free-standing.
