Before You Start
Your OfficeConnect hub comes with:
One power adapter for use with the OfficeConnect hub
A Product Registration card for you to fill out and return
Four rubber feet
A stacking clip
Two unit labels and eight cable ties.
An OfficeConnect Network Assistant CD-ROM.
The extra parts mentioned in the next section are not 
supplied with the hub.
Workstation Connections
To connect workstations or other equipment to your hub, 
you need:
1
A 100BASE-TX adapter card for 
each workstation. 3Com 
produce a range of easy to 
install network adapter cards, 
which provide your 
workstations with 100BASE-T 
connections.
2
An operating system (for example, Netware or Windows 
95/98) with network support configured, running on 
your workstations.
3
One ‘Straight-through’ 100BASE-TX cable for each 
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; refer 
to Figure 5 on page 16. 100BASE-TX cable must be data 
grade (Category 5) shielded or unshielded. We 
recommend that you use shielded cable. The maximum 
length you can use is 100m (328ft).
In order to comply with the 100BASE-TX standard, 
ports designed for workstation connections have been 
marked with the graphical symbol ‘x’ (1x, 2x, 3x, ...). 
This denotes a crossover in the port’s internal wiring.
Hub Connections
To connect to another OfficeConnect hub, you need:
One ‘Straight-through’ 100BASE-TX cable. The maximum 
length is 100m (328ft). Refer to “Connecting 
OfficeConnect Hubs Together” on page 13.
