ABOUT THIS GUIDE

This guide provides all the information you need to install and use a SuperStack® II Switch 3300 unit with default settings. If you want to change the way the Switch works using management software, refer to the “SuperStack II Switch Management Guide” (part number DUA1695-0BAA0x).

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).

This guide is intended for use with both Switch 3300 models:

3C16980 — 24 10BASE-T/100BASE-TX ports

3C16981 — 12 10BASE-T/100BASE-TX ports

All pictures and example screens show the 24-port model, however, all procedures apply to the 24-port model and the 12-port model.

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:

INTRODUCING THE SWITCH 3300

This chapter contains introductory information about the Switch and how it can be used in your network. It covers the following topics:

About the SuperStack II Switch 3300

Switch 3300 — Front View Detail

Switch 3300 — Rear View Detail

Network Configuration Examples

Configuration Rules for Fast Ethernet

Configuration Rules with Full Duplex

12 CHAPTER 1: INTRODUCING THE SWITCH 3300

About the

The SuperStack® II Switch 3300 connects your existing 10Mbps devices,

SuperStack II

connects high-performance workgroups with a 100Mbps backbone or

Switch 3300

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.

Summary of Features The Switch has the following hardware features:

12 or 24 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 System

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).

10BASE-T/ 100BASE-TX Ports

LEDs

The Switch has 12 or 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.

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” on page 31.

*If your Switch has 24 10BASE-T/100BASE-TX ports, these ports are numbered 1 to 24. If your Switch has 12 10BASE-T/100BASE-TX ports, these ports are numbered 1 to 12. For both models, ports supplied through an Expansion Module are numbered sequentially from the last fixed port on the front of the unit.

Power Socket

Redundant Power

System Socket

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.

16 CHAPTER 1: INTRODUCING THE SWITCH 3300

Console Port 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 You can use this slot to install an Expansion Module; for example, a Slot 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.

Matrix Port 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.
