SuperStack II Baseline 10/100 Switches
The 3Com SuperStack II Baseline
10/100 switches provide the highest
performance product in the SuperStack II
Baseline family. Delivering the power of
switched Fast Ethernet while automati-
cally sensing the speed of the connected
devices, the SuperStack II Baseline
switches are ideal for any environment
where raw power and performance are
needed, but management is not
required. The Baseline 10/100 switches
can be used as an aggregation device
connecting to other switches or hubs,
or to provide cost-effective, highest-
performance desktop connections.
The Baseline 10/100 switches
provide 12 or 24 10/100BASE-TX
(Fast Ethernet) switched ports that
automatically detect the speed of
connected devices, optimizing network
performance to 100BASE-TX, where
applicable. The SuperStack II Baseline
switches are unmanaged and work
straight out of the box.
12 or 24 RJ-45 10BASE-T/
100BASE-TX auto-sensing ports
provide the ultimate in high-speed
switching connectivity.
Autonegotiating full-/half-duplex
operation on each port doubles the
speed of each network connection
to 200 Mbps.
MAC addresses support up to
4,000 network devices on your
local area network.

IEEE 802.3x Flow Control ensures
network traffic is not lost during
peaks in traffic rates on high-
throughput, full-duplex links.
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 and port status of each port,
making it easy to spot-check faults
and check individual port status.
802.3x Flow Control
If network traffic becomes so high
that a switch can no longer process
all the data, one of two things may
happen. The switch may drop data
(not retransmit all of it). Network
software protocols will need to
recover lost data, and the network
will be significantly slower.
Alternatively, a switch may be able
to employ methods to ensure that
data is not lost by controlling the
flow of the traffic. IEEE 802.3x

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.
Flow Control allows a switch to
do this.
The potential for very high
network traffic rates is most
acute on 100 Mbps links running
in full-duplex mode. To ensure that
network traffic is not lost, the
SuperStack II Baseline 10/100
Switches employ IEEE 802.3x
Flow Control to keep the network
running at peak performance.
