Fast Ethernet Hubs*

OfficeConnect

Fast Ethernet Hubs

Fast Ethernet networking quite simply

means faster networking—quicker

exchange of data between PCs and

swift downloading from the network.

OfficeConnect delivers these benefits

and more with a new range of Fast

Ethernet products designed specifically

for the small office. At last, Fast

Ethernet is affordable for all users.

Each product features plug-and-play

installation and requires no configura-

tion. An easy-to-read, front-panel

display includes diagnostic LEDs for

monitoring network activity. The Dual

Speed Hubs offer a smooth transition

from 10 to 100 Mbps for maximum

growth and flexibility.

The OfficeConnect Hub TP400 is the

most cost-effective way to add Fast

Ethernet to small-business environ-

ments, branch offices, or independent

workgroups. Compact and reliable,

this hub provides four unmanaged

100BASE-TX ports.

(100 Mbps) Configuration

Rules

All OfficeConnect Fast Ethernet

hubs are Class II. You can directly

connect two Class II Fast Ethernet

hubs (Class I hubs cannot be

directly connected to other Fast

Ethernet hubs). The total length of

cable (A+B+C below) between two

workstations and a nonrepeater

piece of equipment (such as a

switch) must not exceed 205 m

(672 ft). Each cable (A, B, or C)

must not exceed 100 m (328 ft).

3Com recommends that Category 5

cables be used and that the cable

(B) between the Fast Ethernet

hubs is not longer than 5 m

(16.4 ft). This allows the maximum

hub-to-workstation cable length

(A or C) of 100 m (328 ft) to be

used, as shown in the example.

These rules do not apply to Fast Ethernet switches. You can connect as many OfficeConnect

switches together as your business requires.
