Fast Ethernet Hubs
Fast Ethernet (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-work-
station cable length (A or C) of
100 m (328 ft) to be used, as
shown in the example.
