This guide provides all the information you need to install and use a

SuperStack

®

3 Switch 3300 MM (3C16988A) unit with default settings. If

you want to change the way the Switch works using management

software, refer to the “SuperStack Switch Management Guide”.

The guide is intended for use by network administrators who are

responsible for installing and setting up network equipment;

consequently, it assumes a basic working knowledge of LANs (Local Area

Networks).

If the information in the release notes that are shipped with your product

differs from the information in this guide, follow the instructions in the

release notes.

Most user guides and release notes are available in Adobe Acrobat

Reader Portable Document Format (PDF) or HTML on the 3Com

World Wide Web site:

http://www.3com.com/

This guide makes reference to the SuperStack 3 Switch 3300 MM. This

Switch has three fixed Matrix Ports on its rear panel and can be used to

stack any 1100/3300 family Switch. Note that any 1100/3300 family

Switch fitted with a Matrix Module can also be used to stack Switches.

All the Switches mentioned in this guide are compatible with the

Switches found within the SuperStack 1100/3300 family range.

About the

SuperStack 3

Switch 3300 MM

The SuperStack

®

3 Switch 3300 MM connects:

■

your existing 10Mbps devices.

■

high-performance workgroups with a 100Mbps backbone or server

connection.

■

users to dedicated 100Mbps ports in one switch.

In addition, as part of the 3Com

®

SuperStack range of products, you can

combine it with any SuperStack II or SuperStack 3 system as your network

grows.

Summary of Features

The Switch has the following hardware features:

■

24 Fast Ethernet auto-negotiating 10BASE-T/100BASE-TX ports

■

Three Matrix Ports to stack the Switch with up to three other units

from the Switch 1100/3300 family using three Matrix Cables.

■

SuperStack architecture

■

Connects to Redundant Power System/Advanced Redundant

■

19-inch rack or stand-alone mounting

For information about the software features of the Switch, refer to the

“SuperStack Switch Management Guide”.

10BASE-T/

100BASE-TX Ports

The Switch has 24 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.

As these ports are configured as MDIX (cross-over), you need to use a

cross-over cable to connect to devices whose ports are MDIX-only. See

“Choosing the Correct Cables”

on

page 30

for more information.

LEDs

Table 3

(overleaf) lists the LEDs visible on the front of the Switch, and

their states according to color. For information on using the LEDs for

problem solving, see “Solving Problems Indicated by LEDs”

Matrix Ports

The Matrix ports allow you to stack the Switch with up to three other

units from the Switch 1100/3300 family using three Matrix Cables.

Examples

The following illustrations show some examples of how the Switch can be

used in your network.

Switch 3300 MM as a

Segmentation Switch

The example in Figure 3

shows how a Switch 3300 MM stack 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.

The example in Figure 5

shows how a Switch 3300 MM can be used,

within a stack, for a group of users that require dedicated 10Mbps or

100Mbps connections to the desktop. The Switch 3300 SM provides a

Gigabit Ethernet connection to a SuperStack II Switch 9300 in the

basement whilst the Switch 3300 TM provides a Gigabit Ethernet

connection to a local server.
