About the SuperStack II Switch 3300 FX
Summary of Features
The SuperStack® II Switch 3300 FX connects your existing 10Mbps
devices, connects high-performance workgroups with a 100Mbps
backbone or server connection, and connects power users to dedicated
100Mbps ports — all in one switch. In addition, as part of the 3Com
SuperStack II range of products, you can combine it with any SuperStack
II system as your network grows.
The Switch has the following hardware features:
■
Eight Fast Ethernet 100BASE-FX ports
■
Two Fast Ethernet auto-negotiating 10BASE-T/100BASE-TX ports
■
Matrix port for connecting units in the Switch 1100/3300 family to
form a stack:
■
Connect two units back-to-back using a single Matrix Cable
■
Connect up to four units using Matrix Cables linked to a Matrix
Module
■
Slot for an Expansion Module
■
SuperStack II architecture
■
Connects to Redundant Power System / Uninterruptible Power

■
19-inch rack or stand-alone mounting
For information about the software features of the Switch, refer to the
“SuperStack II Switch Management Guide” (DUA1695-0BAA0x).

100BASE-FX Ports
10BASE-T/
100BASE-TX Ports
LEDs
The Switch has eight 100BASE-FX ports capable of operating in half
duplex or full duplex mode. A 2km (6562ft) fiber run is the maximum
length allowed for a segment.
The Switch has two auto-negotiating 10BASE-T/100BASE-TX ports
configured as MDIX (cross-over). These ports can be set to 10BASE-T half
duplex, 10BASE-T full duplex, 100BASE-TX half duplex, 100BASE-TX full
duplex, or they can automatically detect the speed and duplex mode of a
link and provide the appropriate connection. The maximum segment
length is 100m (328ft) over Category 5 twisted pair cable.

This label shows the following:
■
The 3Com product name of the Switch
■
The 3Com 3C number of the Switch
■
The unique MAC address (Ethernet address) of the Switch
■
The serial number of the Switch
You may need this information for fault reporting purposes.
The Switch automatically adjusts its power setting to any supply voltage
in the range 90–240V A.C.
To protect against internal power supply failure, you can use this socket
to connect a SuperStack II Advanced Redundant Power System (RPS) to
the Switch. See “Connecting a Redundant Power System”
on page 29.
The console port allows you to connect a terminal and perform remote or
local out-of-band management. The console port uses standard null
modem cable and is set to auto-baud, 8 data bits, no parity and 1 stop
bit.

Expansion Module
Slot
Matrix Port
You can use this slot to install an Expansion Module; for example, a
100BASE-FX Module that provides an additional high-speed link, or a
Matrix Module that provides four matrix ports for stacking Switch units
together. 3Com provides a range of Expansion Modules; contact your
supplier for availability. For more information about Matrix Modules, see
“Stacking Units”
on page 26.
When an Expansion Module is not installed, ensure the blanking plate is
secured in place.
The matrix port allows you to:
■
Stack the Switch with another unit in the Switch 1100/3300 family
using a single Matrix Cable
■
Stack the Switch with up to three other units in the Switch 1100/3300
family, if one of the units has a Matrix Module installed
For more information about the role of the matrix port, see “Stacking
Units” on page 26.

Switch 3300 FX as a
Segmentation Switch
The following illustrations show some examples of how the Switch can be
used in your network.
The example in Figure 3
shows how a Switch 3300 FX can segment a
network of shared 10Mbps and 100Mbps connections. There is a 10/100
shared segment on each floor, and these segments are connected to the
Switch which is positioned in the basement.

Desktop Switch
The example in Figure 5
shows how a Switch 3300 FX can be used for a
group of users that require dedicated 10Mbps or 100Mbps connections
to the desktop. The Switch has a SuperStack II Switch 1000BASE-SX
Module that allows it to provide a Gigabit Ethernet link to a SuperStack II
Switch 9000 SX in the basement.

Configuration Rules for Fast Ethernet
The topology rules for 100Mbps Fast Ethernet are slightly different to
those for 10Mbps Ethernet. Figure 6
illustrates the key topology rules and
provides examples of how they allow for large-scale Fast Ethernet
networks.
