Positioning the Switch
The switch is suitable for use in an office environment where it can be free-standing or mounted in a
standard 19-inch equipment rack.
Alternatively, the switch can be rack-mounted in a wiring closet or equipment room. A mounting kit,
containing two mounting brackets and four screws, is supplied with the switch.
When deciding where to position the switch, ensure that:
z It is accessible and cables can be connected easily.
z Cabling is away from sources of electrical noise. These include lift shafts, microwave ovens, and
air conditioning units. Electromagnetic fields can interfere with the signals on copper cabling and
introduce errors, therefore slowing down your network.
z Water or moisture cannot enter the case of the unit.
