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.

12 or 24 RJ-45 10BASE-T 
connections

MDI/MDIX switchable port
allows for simple cascading of hubs
without the need for special
crossover cable.

Slot for optional transceiver inter-
face module provides a connection
to legacy networking devices or
fiber. 

19” size for easy installation in a
wiring closet. A rackmounting kit 
is supplied. The product can also 
be used free-standing.

Diagnostic LEDs indicate network
traffic, port status, and collisions,
making it easy to spot-check faults
and check individual port status.

3Com lifetime limited warranty

Connection for the SuperStack II
Advanced Redundant Power
System provides ultimate protec-
tion against network downtime.
The SuperStack II Advanced
Redundant Power System 
and Uninterruptible Power System
are available as options 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.
