for a low cost, high performance
Gigabit network, small to mid-sized
businesses will find an affordable,
unmanaged, out-of-the-box solution –
the family of 3Com®SuperStack®3
Baseline switches and hubs.
High Performance, Rack-Mounted
SuperStack 3 Baseline switches and
hubs have the power to work in the
most demanding business networks,
and their standard 19-inch, one rack-
unit-high (1RU) form factor, consistent
across the family, makes them an ideal
fit for the tightest wiring closets.
Ultra Reliability
As with other 3Com products,
SuperStack 3 Baseline switches and
hubs feature sturdy design and con-
struction, which pays off in high
reliability and long service life.
Advanced Switching Features
The 3Com SuperStack 3 Baseline
switches also support Class-of-Service
traffic prioritization via the IEEE
802.1p standard, so they can fit easily
within larger, enterprise LANs, run-
ning real-time applications.
Plug-and-Play Operation
3Com SuperStack 3 Baseline switches
and hubs operate out of the box, with
no configuration required. Built-in
features simplify operation, such as
10/100 auto-sensing ports that adjust
to the speed of the connected PC or
device, and automatic MDI/MDIX
Ethernet cable detection on all ports
of all switches that automatically
adapts to the Ethernet cable type
used, simplifying installation.
Limited Lifetime Warranty
Ensures peace of mind when purchas-
ing SuperStack 3 Baseline products.
Enterprise divisions, branch offices,
and small businesses alike appreciate
the easy affordability and wide perfor-
mance range of SuperStack 3 Baseline

Ethernet (10 Mbps) speeds, the 3Com
SuperStack 3 Baseline 10/100 16-port
and 24-port switches are the ideal
solution. They come pre-configured
for fast, easy installation. They feature
full non-blocking performance, auto-
negotiation capability, IEEE 802.1p
traffic prioritization, and automatic
MDI/MDIX Ethernet cable detection
on all ports.
3Com SuperStack 3 Baseline 10/100
Switches (with Gigabit Uplinks)
For offices requiring Fast Ethernet
(100 Mbps) connections for desktops,
and ultra high-speed Gigabit connec-
tions to servers or high-speed network
backbones, the 3Com SuperStack 3
Baseline 10/100 switches with Gigabit
uplinks are the recommended solution.
One switch model delivers 48 10/100
ports, as well as two 10/100/1000
uplink ports. Also available is a
24 10/100-port switch with two
10/100/1000 uplink ports. Both feature
full non-blocking performance, auto-
negotiation capability, IEEE 802.1p
prioritization, and automatic
MDI/MDIX Ethernet cable detection
on all ports.
3Com SuperStack 3 Baseline 10/100/1000
Switch
The SuperStack 3 Baseline 10/100/1000
switch is ideal for users who want the
high-speed performance of
10/100/1000 switching but do not need
sophisticated management capabilities.
The SuperStack 3 Baseline 10/100/1000
switch is pre-configured and ready to
use straight from the box. It provides
eight RJ-45 10/100/1000 auto-sensing
ports and features full non-blocking
performance, IEEE 802.1p traffic pri-
oritization, auto-negotiation capability,
automatic MDI/MDIX Ethernet cable
detection on all ports and full-duplex/
half-duplex mode. Diagnostic LEDs
indicate network traffic and port status
of each port, making it easy to spot-
check faults and check individual port
status.
3Com SuperStack 3 Baseline
Dual Speed Hubs
With SuperStack 3 Baseline Dual Speed
Hubs, businesses can protect their net-
work investment while gradually
moving up to Fast Ethernet.
Available with 16 or 24 ports, these
products feature auto-negotiation capa-
bility, so they automatically adjust to
the speed of each communicating
device. They're pre-configured, for
out-of-the-box installation, and they
can be cascaded together to provide
additional capacity without uprooting
existing network equipment.
