The 3Com SuperStack II Baseline
hubs provide high-quality connectivity
solutions at entry-level prices for shared
Ethernet networks that don’t require
comprehensive management. These
hubs are ideal for low-intensity network
environments such as general office
applications using small networked files.
With the lowest per-port cost in the
SuperStack II range, the Baseline hubs
offer exceptional value for money, and
provide the most cost-effective way to
add new users to a network.
The SuperStack II Baseline Hubs
provide 12- or 24-10BASE-T RJ-45
ports, allowing each hub to connect
either 12 or 24 users. Each hub has an
MDI/MDIX switch, which connects
multiple hubs—expanding the network
using normal UTP cabling. The
Baseline hubs provide a transceiver
interface slot, allowing connection to
alternative network media, such as
fiber or coax. Optional transceiver
interface modules are available from
3Com.

SuperStack II Baseline Hubs
The 12- and 24-port Baseline Hubs
are equipped with a slot ready to
accommodate one of 3Com’s slide-in
transceiver interface modules.
Here are some ways to use them:
1.
They allow you to connect to legacy
equipment via 10BASE2 (coaxial)
cable or AUI cable. The following
transceiver interface modules can
be used for this:
■
Coaxial Module
BNC connector
(3C1206-6) – Provides direct
connection to a 10BASE2 (coaxial)
network via a BNC connector.
■
AUI Module
female AUI connector
(3C1206-0) – Provides connection
to an external transceiver via an
AUI connector.
■
Fan-Out Module
male AUI connector
(3C1206-4) – Provides direct connec-
tion to a PC, server, or network
device via an AUI cable.
2.
They can give you a direct interface
from your Baseline Hub to a 10 Mbps
fiber link (for example, a campus
backbone connection). The following
variants are available:
■
10BASE-FL Module
with ST fiber
connector (3C1206-5)
■
10BASE-FB Module
with ST fiber
connector (3C12067)
3.
They can provide you with an
additional 10BASE-T port.
