Unit Connections

To connect OfficeConnect units (such as hubs and
switches) to your Switch, you need:
One suitable TP cable for each unit.

Workstation Connections

To connect workstations or other equipment (such as
servers) directly to your Switch, you need:
1One 10BASE-T, 100BASE-TX
or 10/100BASE-TX adapter
card for each workstation.
3Com produce a range of
easy to install network
adapters, which provide your
workstation with a 10BASE-T
or 100BASE-TX connection.
2One suitable TP cable for each workstation.
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...
You also need a network operating system running
on your workstations.

Twisted Pair (TP) C ables

To connect your hubs and workstations to the Switch,
you must use ‘straight-through’ TP cables with RJ-45
connectors (all OfficeConnect products use RJ-45 type
connectors). Your supplier should stock suitable
cables.
A ‘straight-through’ cable is one where each pin of
one connector is connected to the same pin of the
other connector.
Cables can be shielded (screened) or unshielded; we
recommend that you use shielded cable. Cables used
for 100BASE-TX connections must be data grade
(Category 5). The maximum length you can use is
100m (328ft).
Positioning Your OfficeConnect Switch
When installing your OfficeConnect 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.
Using the Rubber Feet and Stacking Clips
The four self-adhesive rubber feet prevent your
Switch from sliding around on your desk. Stick the
feet to the marked areas at each corner of the
underside of your Switch.
The four stacking clips are used for neatly and
securely stacking your OfficeConnect units together.
You can stack up to 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:
1Place your new unit
on a flat surface.
Your clips fit in these
positions on the side
of the unit:
2Position 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.
3Keeping the front of
the units aligned, rest
the bottom of the
existing unit on the
clips’ spikes. Push the
clips firmly into the
existing unit until they
click into place.
Repeat these steps to secure the other side.
To remove a clip, hol d 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.
