ABOUT THIS GUIDE

This guide provides all the information you need to install and use a SuperStack® II Switch 3300 SM (3C16987) 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”.

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 II 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 II 1100/3300 family range.

About the

SuperStack II

Switch 3300 SM

Summary of Features

The SuperStack® II Switch 3300 SM connects:

■your existing 10Mbps devices.

■high-performance workgroups with a 100Mbps or 1000Mbps backbone or server connection.

■users to dedicated 100Mbps ports 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:

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

■1000BASE-SX Gigabit Ethernet port

■One Matrix Port for connecting units in the Switch 1100/3300 family to form a stack. This enables you to:

■Connect two units back-to-back using a single Matrix Cable

■Stack the Switch with up to three other units in the Switch 1100/3300 family, when one of the units is a Switch 3300 MM unit

■SuperStack II architecture

■Connects to Redundant Power System/Advanced Redundant 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”.

10BASE-T/ The Switch has 24 auto-negotiating 10BASE-T/100BASE-TX ports 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.

1000BASE-SX Port The Switch has a Gigabit Ethernet Port that provides a 1000Mbps connection to another Gigabit Ethernet device. This port uses 62.5 m or 50 m multimode fiber optic cable with MT-RJ duplex connectors.

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” on page 31.

Status	Green	A link is present, and the port is enabled.
	Green flashing	A link is present, but the port is disabled.
	Off	No link is present.
Unit LEDs
1–8	Green	The Switch forms a stack with other Switch units;
		the LED indicates the position of the Switch in the

		there are eight LEDs, only four Switch units can be
		stacked at present.
	Off	The Switch is stand-alone.
Power/Self Test LED
	Green	The Switch is powered-up.
	Green flashing	The Switch is either downloading software or is
		initializing (which includes running a Power On Self
		Test).
	Yellow	The Switch has failed its Power On Self Test.
	Off	The Switch is not receiving power.

■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 (ARPS) to the Switch. See “Connecting a Redundant Power System” on page 29.

16 CHAPTER 1: INTRODUCING THE SWITCH 3300 SM

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.

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, when one of the units is a Switch 3300 MM unit

For more information about the role of the Matrix Port, see “Stacking

Units” on page 26.

Network Configuration Examples

Configuration	used in your network.
Examples
Switch 3300 SM as a	The example in Figure 3 shows how a Switch 3300 SM stack can segment

	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 Switch
	3300 SM also provides a Gigabit Ethernet connection to a local server.
