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.

(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.
