Positioning Your OfficeConnect Hub
When installing your OfficeConnect hub, 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 25.4 mm (1in.) clearance.
Securing Your Hub
There are two slots on the underside of the OfficeConnect
hub which can be used for wall mounting. It is
recommended that you mount the hubs 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.
For Hub 4 or Hub 8:
Make two screw holes 150mm
(5.9in.) apart. Use the guide at the back of this manual to
mark the position of the holes.
For Hub 12:
Make two screw holes 142mm (5.6in.) apart.
Use the guide at the at the back of this manual 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 hub and locate it over the
screw heads. When in line, gently push the hub on to the
wall and move it downwards to secure. When making
connections, be careful not to push the hub 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.
