Workstation Connections

To connect workstations and other equipment t o your

hub, you need :

100BASE-TX adapter card s

for every workstation . 3Com

produce a range of easy to

install network adapters,

which provide your

workstations with

100BASE-TX connections .

A network operating system running on your

workstations.

O ne 'Straight-through' 100BASE-TX cable for every

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. 100BASE-TX cable m ust be data grade

(Category 5) shielded or unshielded. We recommend

that you use shielded cable. The maximum length you

can use is 100 m eters (328 feet) .

In order to comply with the 100BASE-TX 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 another OfficeConnect h ub to connect to,

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:

Place your new u nit on

a flat surface. Your clips

fit in the se positions on

the side of the unit :

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.

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.
