Positioning Your Switch
When installing your Switch, ensure:
■
It is out of direct sunlight and away from sources of
heat.
■
Cabling is away from power lines, fluorescent lighting
fixtures, and sources of electrical noise such as radios,
transmitters and broadband amplifiers.
■
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 recommend you
provide a minimum of 25mm (1in.) clearance.
Securing Your Switch
There are two slots on the underside of the OfficeConnect
Switch that can be used for wall mounting. It is
recommended that you mount the Switch with the LEDs
facing upwards to prevent dust entering the cooling vents.
When wall mounting the unit, ensure that it is within
reach of the power outlet.
You need two suitable screws. Ensure that the wall you are
going to use is smooth, flat, dry and sturdy. Make two
screw holes which are 142mm (5.6in.) apart. Use the guide
on page 31 to mark the position of the holes. Fix the screws
into the wall, leaving their heads 3mm (0.12in.) clear of the
wall surface.
Remove any connections to the unit and locate it over the
screw heads. When in line, gently push the unit on to the
wall and move it downwards to secure. When making
connections, be careful not to push the unit up and off the
wall.
CAUTION : Only wall mount single units, do not wall
mount stacked units.
Also available from 3Com, is the OfficeConnect Mounting
Unit (part number 3C16765). This allows you to firmly
secure a stack of OfficeConnect devices to the desktop or
onto a shelf in a rack.
