This guide
The extra parts mentioned below are not supplied with
the hub.
Workstation Connections
To connect workstations or other equipment t o your
hub, you need :
10BASE-T connections for
1
all your equipment. 3Com
produce a range of easy to
install network adapters,
which provide your
workstations with
10BASE-T connections .
An operating system with network support configured,
2
running on your workstations.
One 'Straight-through' 10BASE-T cable for every
3
workstation or piece of equipment.
A 'Straight-through' cable is one where the pins of one
connector are connected to the same pins of the other
connector. 10BASE-T cables can be shielded or
unshielded. We recommend you use shielded. The
maximum length you can use is 100 meters (328 feet).
In order to comply with the 10BASE-T standard, ports
designed for workstation connections have been marked
with the graphical symbol 'x' . This denotes a crossover in
the port' s internal wiring, for example 1x, 2x, 3x...
Hub Connections
If you have additional hubs you want to connect using
10BASE-2 (Coax), you need:
One 10BASE-2 50 Ohm cable for each additional hub.
The minimum cable length you can use is 0.5 meters
(1.6 feet). The maximum segment length you can have
is 185 meters (607 feet).
One 10BASE-2 'Y' piece for each hub. You can use 'T'
pieces but 'Y' pieces provide optimum clearance of the
other ports.
Two 10BASE-2 50 Ohm terminators (end pieces).
If you have additional hubs you want to connect using
10BASE-T, you need:
One 'Straight-through' 10BASE-T cable for each
additional hub.

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:
Place your new unit on
1
a flat surface. Your clips
fit in these positions on
the side of the unit:
Position a clip over one of
2
these holes and push it in
until it clicks into place.
Repeat this for the other
clip position on the same
side.
Keeping the front of the
3
units aligned, rest the
bottom of the new unit
on the clips' spikes. Push
the clips firmly into the
new unit until they click
into place.
Repeat these steps to secure the other side.
To remove a clip, hold the units firmly with one hand
and hook the first finger of your other hand around the
back of the clip. Use reasonable force to pull it off.

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.
