you need:
■
One ‘Straight-through’ 100BASE-TX cable, less than
5 meters (16.4 feet) in length.
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 (1 in) clearance.
Using the Rubber Feet and Stacking Clips
The four self-adhesive rubber feet prevent your hub from
sliding around on your desk. Stick the feet to the marked
areas at each corner of the underside of your hub.
The four stacking clips are used for neatly and securely
stacking your OfficeConnect units together.
You can
stack up to a maximum of four units. Small units
must be stacked above large units.
To stack your
units, secure the clips on one side and then on the other.
Use the following method to secure one side:
1
Place your
new u
nit on
a flat surface. Your clips
fit in the
se
positions on
the side of the unit
:
2
Position a clip over one
of these holes and
push it in until it clicks
into place. Repeat this
for the other clip
position on the same
side.
3
Keeping the front of
the units aligned, rest
the bottom of the
existing u
nit on the
clips’ spikes. Push the
clips firmly into the
existing u
nit until they
click into place
.
R
epeat these steps to secure the other side.
To remove a clip, hold the units firmly with one hand
and hook the
first f
inger of your other hand around the
back of the clip. Use reasonable force to pull it off.
