WARNING: RJ-45 Ports. These are shielded RJ-45 data sockets. They cannot be used as standard traditional telephone sockets, or to connect the unit to a traditional PBX or public telephone network. Only connect RJ-45 data connectors, network telephony systems, or network telephones to these sockets.

Either shielded or unshielded data cables with shielded or unshielded jacks can be connected to these data sockets.

The Switch 4200G has 12, 24 or 48 auto-negotiating 10BASE-T/100BASE-TX ports configured as Auto MDIX (crossover). When auto-negotiation is enabled these ports automatically operate in MDI or MDIX mode as needed. These ports provide 10/100/1000 Mbps full-duplex connections to other Gigabit Ethernet devices. Full-duplex allows packets to be transmitted and received simultaneously which effectively doubles the potential throughput of a link.

These ports require either straight-through or cross-over Category 5 cables with RJ-45 connectors at each end. The maximum UTP cable length is 100 m (328 ft) over Category 5 cable.

The 10/100/1000BASE-T ports will auto-negotiate the appropriate speed.

Switch 4200G—Front View Detail 17

1000BASE-X SFP Ports SFP (Small Form Factor Pluggable) ports support fiber Gigabit Ethernet

long-wave (LX), long-haul (LH70) and copper (T) SFP Transceivers in any combination. This offers you the flexibility of using SFP transceivers to provide connectivity between the Switch and remote 1000 Mbps workgroups or to create a high capacity aggregated link backbone connection.

The default state for these ports is auto-negotiation enabled, where the speed, duplex and flow control modes are negotiated. As the speed and duplex modes are fixed by the media type, only the flow control is negotiated with the link partner. Alternatively, auto-negotiation can be disabled (except 1000BASE-T which auto-negotiation is mandatory) and the flow control setting can be manually configured.

Console Port The console port allows you to connect a terminal and perform remote or

local out-of-band management. As the console port on the Switch is an RJ-45 port, you will need to connect an RJ-45 to DB9 converter cable to a standard null modem cable in order to connect a terminal.

Unit Status Display The Status Display is a seven segment display visible on the front of the

Switch. The Status Display indicates switch status conditions such as the unit number, POST test ID, and software upgrade information. In the unlikely event of a hardware fault occurring, the Status Display may be used to help diagnose the problem. For information on using the Status Display for problem solving, see “Solving Problems Indicated by LEDs” on page 54.

■ power lines and fluorescent lighting fixtures

■ The Switch is accessible and cables can be connected easily.

Rack-mounting 23

■ Water or moisture cannot enter the case of the Switch.

■ Air flow is not restricted around the Switch or through the vents in the

side of the Switch. 3Com recommends that you provide a minimum of

25mm (1in.) clearance.

■ Air temperature around the Switch does not exceed 40 °C (104 °F).

If the Switch is installed in a 19-inch rack or closed assembly its local air temperature may be greater than room ambient temperature.

■ The air is as free from dust as possible.

■ The unit is installed in a clean, air conditioned environment.

■ No more than four Switch units are placed on top of one another, if

the units are free-standing.

■ The Switch is situated away from sources of conductive (electrical)

dust, for example laser printers.

■ The AC supply used by the Switch is separate to that used by units

that generate high levels of AC noise, for example air conditioning

units and laser printers.

Rack-mounting The Switch 4200G is 1 rack unit (1U) high and will fit in most standard

19-inch racks.

CAUTION: Disconnect all cables from the Switch before continuing. Remove all self adhesive pads from the underside of the Switch if they have been fitted.

To rack-mount your Switch:

1 Place the Switch the right way up on a hard flat surface, with the front

facing towards you.

2 Locate a mounting bracket over the mounting holes on one side of the

front of the Switch, as shown in Figure 5.

You can also rack mount your Switch using the mounting holes at the rear of the Switch.

24 CHAPTER 2: INSTALLING THE SWITCH

Powering-up the

Switch 4200G

If the Switch units are free-standing, up to four units can be placed one on top of the other. If you are mixing a variety of 3Com equipment, the smaller units must be positioned at the top.

If you are placing Switch units one on top of the other, you must use the self-adhesive rubber feet supplied. Apply the feet to the underside of each Switch, sticking one in the marked area at each corner. Place the Switch units on top of each other, ensuring that the feet of the upper unit sit fully on the lower unit.

The following sections describe how to get your Switch 4200G powered-up and ready for operation.

Use the following sequence of steps to power-up the Switch.

1 Plug the power cord into the power socket at the rear of the Switch.

2 Plug the other end of the power cord into your power outlet.

The Switch powers-up and runs through its Power On Self Test (POST), which takes approximately one minute.

Checking for Correct

Operation of LEDs

During the Power On Self Test, all ports on the Switch are disabled and the LEDs light. The PWR LED will flash green during the POST.

When the POST has completed, check the PWR LED to make sure that your Switch is operating correctly. Table 7 shows possible colors for the LED.

To be recognized as valid, the SFP transceiver must have the following characteristics:

■ 1000BASE-LX SFP transceiver

Use this transceiver to connect Gigabit Ethernet SFP ports on the Switch directly to a single-mode fiber-optic cable or to multimode fiber using a conditioned launch cable.

■ 1000BASE-LH70 SFP transceiver

Use this transceiver to connect Gigabit Ethernet SFP ports on the Switch directly to a single-mode fiber-optic cable.

SFP Operation 27

■ 1000BASE-T SFP transceiver

This transceiver uses Category 5 copper cabling with RJ-45 connectors

and supports segment lengths of up to 100 m (328 ft).

If the SFP transceiver is faulty, it will not operate within the Switch. See “Solving Hardware Problems” on page 55.

3Com recommends that you only use SFPs supplied by 3Com. If the SFP transceiver is invalid it will not be recognized by the Switch.

Use the following sequence of steps to activate the SFP ports:

1 The SFP transceiver is keyed and there is only one way in which it can be

installed correctly. It is not necessary to power-down your Switch.

2 Hold the transceiver so that the connector is toward you and the product

label is visible. Ensure the wire release lever is closed (in the upright position).

3 Gently slide the transceiver into the SFP port until it clicks. If the

transceiver does not click into place, remove it, turn it over and re-insert.

4 Remove the plastic protective cover if fitted.

5 Use and appropriate cable to connect the transceiver to a suitable device.

6 Check the LEDs on the front of the Switch to ensure that it is operating

correctly. Refer to “LEDs” on page 18 for more information.

28 CHAPTER 2: INSTALLING THE SWITCH

Removing an SFP

Transceiver

Choosing the Correct Cables

If you wish to remove the transceiver (it is not necessary to power-down your Switch):

1 Disconnect the cable from the transceiver.

2 Move the wire release lever downwards until it is pointing toward you.

3 Pull the wire release lever toward you to release the catch mechanism;

the transceiver will then easily slide out.

All of the ports on the Switch are Auto-MDIX, that is they have a cross-over capability. These ports can automatically detect whether to operate in MDI or MDIX mode. Therefore you can make a connection to one of the ports with a straight-through (MDI) or a cross-over cable (MDIX).

The Auto-MDIX feature only operates when auto-negotiation is enabled.

If auto-negotiation is disabled, all the Switch ports are configured as MDIX (cross-over). If you want to make a connection to another MDIX port, you need a cross-over cable. Many ports on workstations and servers are configured as MDI (straight-through). If you want to make a connection to an MDI port, you need to use a standard straight-through cable. See Table 8.

3Com recommends that you use at least Category 5 twisted pair cable—the maximum segment length for this type of cable is 100 m (328 ft.).

Choosing the Correct Cables 29

CAUTION: If you want to install the Switch using a Category 5E or Category 6 cable, 3Com recommends that you briefly connect the cable to a grounded port before connecting network equipment. If you do not, the cable’s Electrostatic Discharge (ESD) may damage the Switch's port.

You can create a grounded port by connecting all wires at one end of a UTP cable to an earth ground point, and the other end to a female RJ-45 connector located, for example, on a Switch rack or patch panel. The RJ-45 connector is now a grounded port.

3Com recommends that you use Category 5 twisted pair cable—the maximum segment length for this type of cable is 100 m (328 ft).

Choosing the Correct

Cables for the

Switch 4200G

All of the ports on the front of the Switch 4200G 28-Port are 100BASE-FX MT-RJ multi-mode ports. The MT-RJ port is a small form factor fiber-optic port with the transmit and receive fibers in the same cable. Unlike many fiber-optic systems, only one MT-RJ cable is needed to connect two MT-RJ ports together.

To connect a front panel port to another 100BASE-FX MT-RJ multi-mode port, or to a patch panel, a single MT-RJ multi-mode pinless jumper cable is required. Since standard MT-RJ cables are cross-over cables, no Auto-MDIX sensing is required. The maximum cable length is 2 kilometers (1.24 miles).

CAUTION: Do not connect pinned MT-RJ connectors into any port on the Switch 4200G as this may damage the unit. The ports have locator pins fitted and are designed for standard (pinless) connectors.

To connect a front panel port to a 100BASE-FX single mode port, or to a port that does not have an MT-RJ connector, an adaptor will be required. It is not possible to connect a front panel port to a 1000BASE-FX port.

30 CHAPTER 2: INSTALLING THE SWITCH

3 SETTING UP FOR MANAGEMENT

To make full use of the features offered by your Switch, and to change and monitor the way it works, you have to access the management software that resides on the Switch. This is known as managing the Switch.

Managing the Switch can help you to improve the efficiency of the Switch and therefore the overall performance of your network.

This chapter explains the initial set up of the Switch and the different methods of accessing the management software to manage a Switch. It covers the following topics:

Command Line

Interface

Management

To manage your Switch you can use one of the following methods:

■ Command line interface management

■ Command line interface management using SSH

■ Web interface management

■ SNMP management

Each Switch has a command line interface (CLI) that allows you to manage the Switch from a workstation, either locally using a console port connection (see Figure 7), or remotely over the network (see Figure 8).

Methods of Managing a Switch 33

There are two main views in the CLI:

■ User View

This view is shown when you first connect to the Switch and shows

basic information about operation and statistics. The prompt for user

view is <S4200G>.

■ System View

This view enables you to configure the system parameters. To display

this view, from user view enter system-view. The prompt for system

view is [S4200G].

Management

The Switch 4200G supports Secure Shell version 1.5 (SSHv1.5), allowing secure access to the Command Line Interface of the Switch.

If you use SSH to administer your Switch and the network traffic is intercepted, no passwords or configuration information will be visible in the data. To securely administer the Switch using the Command Line Interface you need a third party SSH client.

Each Switch has an internal set of web pages that allow you to manage the Switch using a Web browser remotely over an IP network (see Figure 9).

CAUTION: To protect your Switch from unauthorized access, you must change all three default passwords as soon as possible, even if you do not intend to actively manage your Switch. For more information on default users and changing default passwords, see “Default Users and Passwords” on page 50.

36 CHAPTER 3: SETTING UP FOR MANAGEMENT

IP Configuration You can use one of the following methods to allocate IP information to

your Switch (essential if you wish to manage your Switch across the network).

Manual IP Configuration

When you configure the IP information, the Switch remembers the information that you enter until you change it again.

You should use the Manual IP configuration method if:

■ you do not have a DHCP or BootP server on your network, or

■ you want to remove the risk of the IP address ever changing, or

■ your DHCP or BootP server does not allow you to allocate static IP

addresses. (Static IP addresses are necessary to ensure that the Switch is always allocated the same IP information.)

For most installations, 3Com recommends that you configure the Switch IP information manually. This makes management simpler and more reliable as it is not dependent on a DHCP or BootP server, and eliminates the risk of the IP address changing.

To manually enter IP information for your Switch, work through the “Manually Configuring IP Information” on page 37.

Automatic IP Configuration using DHCP

By default the Switch tries to configure itself with IP Information without requesting user intervention. It tries to obtain an IP address from a DHCP server on the network.

When using automatic IP configuration it is important that the IP address of the Switch is static, otherwise you will not know what the IP address is and it will be difficult to manage. Most DHCP servers allow static IP addresses to be configured so that you know what IP address will be allocated to the Switch. Refer to the documentation that accompanies your DHCP server.

For a detailed description of how automatic IP configuration operates, please refer to the Configuration Guide on the CD-ROM that accompanies your Switch or the 3Com Web Site.

Manually Configuring IP Information 37

You should use the automatic IP configuration method if:

■ your network uses DHCP to allocate IP information, or

■ flexibility is needed. If the Switch is deployed onto a different subnet,

it will automatically reconfigure itself with an appropriate IP address, instead of you having to manually reconfigure the Switch.

If the Switch is not allocated with an automatic IP address, the IP configuration will be blank or shown as ‘’’’.

If you use the automatic IP configuration method, you need to discover the automatically allocated IP information before you can begin management. Work through the “Viewing Automatically Configured IP Information” on page 44.

Preparing for

Management

Manually Configuring IP Information

Once your Switch’s initial set up is complete you can set up your chosen management method as described in “Methods of Managing a Switch” on page 32.

For detailed information about the specific web interface operations and command line interface commands and problem solving, refer to the “Switch 4200G Command Reference Guide” on the CD-ROM that is supplied with the Switch or on the 3Com Web site.

You can manually configure the Switch IP information in the following ways:

■ Connecting to the console port

Connect a workstation using a console cable to the console port of the Switch. You can then manually enter IP information using the command line interface (CLI).

■ Connecting to a front panel port

Connect a workstation using an Ethernet cable to a front panel port of the Switch. You can then manually enter IP information using the web interface or the command line interface (CLI).

38 CHAPTER 3: SETTING UP FOR MANAGEMENT

Connecting to the

Console Port

To set up your Switch manually you can make a connection to the console port, (this example describes a local connection to the console port, rather than one using a modem). You can do this whilst the Switch is offline, that is, before you connect the Switch to a network, or whilst the Switch is online, that is, connected to a network.

Prerequisites

■ A workstation with terminal emulation software installed, such as

Microsoft Hyperterminal. This software allows you to communicate with the Switch using the console port directly.

■ Documentation supplied with the terminal emulation software.

■ The console cable (RJ-45) supplied with your Switch.

You can find pin-out diagrams for the cable in Appendix on page 89.

■ You need to have the following so that you can manually set up the

Switch with IP information:

■ IP address

■ subnet mask

■ default gateway

■ management VLAN ID, normally set to the default value (1)

Connecting the Workstation to the Switch

to your Switch as the configuration is not saved automatically when the Switch is powered down.

The initial set up of your Switch is now complete and the Switch is ready for you to set up your chosen management method. See “Methods of Managing a Switch” on page 32.

Viewing Automatically Configured IP Information

Using 3Com Network

Director

If you allow the Switch to automatically configure its own IP information you need to discover and view the IP information before you can begin to manage the Switch. You can discover the IP information in two ways:

■ Using 3Com Network Director

This application will auto-discover the Switch and display the automatically allocated IP information assigned to the Switch.

■ Connecting to the Console Port

Connect a workstation using a console cable to the console port of the Switch. You can then view the IP information automatically assigned to the Switch using the command line interface (CLI).

You can use the 3Com Network Director application (available from the 3Com website) to discover the automatically allocated IP information.

1 Connect your Switch to the network.

2 Power-up the Switch and wait for two minutes.

3 Launch 3Com Network Director and run the Auto-discovery wizard.

3Com Network Director will auto-discover the new Switch and display the IP information that has been automatically allocated to the Switch.

Most DHCP and BootP servers allow static IP addresses to be configured so that you know what IP address the Switch will be given. Refer to the documentation that accompanies your DHCP or BootP server.

If your network does not have a DHCP or BootP server, the workstation running 3Com Network Director must be on the same subnet as the Switch, because Auto-IP addresses are non-routable.

Viewing Automatically Configured IP Information 45

Connecting to the

Console Port

Alternatively, you can view the automatically configured IP information using the command line interface (CLI) through a connection to the console port. (This example describes a local connection to the console port, rather than a remote one using a modem.) For further information on connecting using the console port see “Connecting the Workstation to the Switch”on page 38.

Viewing IP Information using the Console Port

You are now ready to view the automatically allocated IP information using the command line interface.

1 Connect your Switch to the network using the Ethernet cable. As soon as

a network connection is made the Switch begins the automatic IP configuration process.

The automatic IP configuration process usually completes within one minute.

2 The command line interface login sequence begins as soon as the Switch

detects a connection to its console port.

If the login prompt does not begin immediately, press Return a few times until it starts.

3 At the login and password prompts, enter

admin as your user name and

press Return at the password prompt. If you have logged on correctly, <S4200G> is displayed as shown in the example in Figure 16.

48 CHAPTER 3: SETTING UP FOR MANAGEMENT

The switch automatically generates a host key pair when it is powered up for the first time, or after any reset to factory defaults. Host key generation may take a while, during which time SSH connections to the switch will be refused.

4 Install an SSH client application on the workstation you want to use to

access the switch.

3Com recommends the following SSH clients; PuTTY, OpenSSH and SSH Communications Security Corp Secure Shell.

5 Open an SSH session and access the Switch using the Switch’s IP address

and port number.

The first time you connect to the switch the client will ask you to confirm that the host key is correct for the device.

6 The Switch and the SSH client will authenticate each other and a secure

connection will be established.

7 Enter your usual username and password to access the CLI commands.

For increased security please change the default password when using SSH for the first time.

Setting Up SNMP Management V1 or V2

Prerequisites

Any network management application running the Simple Network Management Protocol (SNMP) can manage a Switch if:

■ The correct Management Information Bases (MIBs) are installed on the

management workstation.

■ The management workstation is connected to the Switch using a port

in VLAN 1 (the Default VLAN). By default, all ports on the Switch are in VLAN 1.

You can use the 3Com Network Director application that is available from the 3Com website to provide SNMP management for your Switch. If you use 3Com Network Director it automatically loads the correct MIBs and necessary files onto your workstation.

■ Documentation supplied with the SNMP network management

application software.

The default read community string is public. To change this setting in System View, enter display snmp community.

The default write community string is private. To change this setting in System View, enter display snmp community.

To manage your Switch using an SNMP network management application, you need to specify SNMP community strings for the users defined on the Switch. You can do this using the command line interface system management snmp community command. Refer to the command line interface section of the “SuperStack 4 Switch Command Reference Guide” for more information.

Default Users and Passwords

SNMP V3 is on as default. All commands are in snmp menu in System View.

If you intend to manage the Switch using the web interface or the command line interface, or to change the default passwords, you need to log in with a valid user name and password. The Switch has three default user names, and each user name has a different password and level of access. These default users are listed in Table 10.

Configuration Conversion Utility 51

CAUTION: To protect your Switch from unauthorized access, you must change all three default passwords as soon as possible, even if you do not intend to actively manage your Switch.

4 PROBLEM SOLVING

This chapter helps you to diagnose and solve problems you may have with the operation of your Switch. There is also an explanation of IP addressing and upgrading software.

The topics covered are:

■ Solving Problems Indicated by LEDs

■ Solving Hardware Problems

■ Solving Communication Problems

■ Solving Fabric Formation Problems

If you experience a problem that is not listed here, it may be included in the Support section of the Switch 4200G Command Reference Guide on the CD-ROM that accompanies your Switch.

For Technical Support information, see Appendix D.

54 CHAPTER 4: PROBLEM SOLVING

Solving Problems Indicated by LEDs

If the LEDs on the Switch indicate a problem, refer to the list of suggested solutions below.

The PWR LED does not light

Check that the power cable is firmly connected to the Switch and to the supply outlet. If the connection is secure and there is still no power, you may have a faulty power cord or an internal fault. Firstly, check the power cord by:

■ testing it in another device.

■ connecting a working power cord to the ‘problem’ device then

contact your supplier for advice.

On powering-up, the PWR LED lights Red

The Switch unit has failed its Power On Self Test (POST) because of an internal problem. The fault type will be indicated on the unit LEDs. Contact your supplier for advice.

On powering-up, the PWR LED is flashing yellow

A port has failed and has been automatically disabled. You can verify this by checking that the Port LED is quickly flashing Yellow. If a port fails, the Switch passes its Power On Self Test and continues to operate normally.

A Port LED is flashing yellow

The port has failed and has been automatically disabled. The Switch passes its Power On Self Test and continues to operate normally, even if one or more ports are disabled.

A link is connected and yet the Port LED does not light

Check that:

■ The Switch and the device at the other end of the link (or cable) are

connected securely.

■ The devices at both ends of the link are powered-up

■ The quality of cable is satisfactory

■ Auto-negotiation settings are the same at both ends.

Solving Hardware Problems 55

Auto-negotiation problems will occur with 10BASE-T or 100BASE-T where auto-negotiation is disabled and incorrect cables are being used (cross-over or straight)

Auto-negotiation problems will occur with fiber if:

■ The Receiver (RX) and Transceiver (TX) cable connectors are

swapped

■ Fibers are broken

■ Auto-negotiation differs at either end (a link appears at the ‘fixed’

end and not at the auto-negotiation end)

Solving Hardware Problems

In the rare event of your Switch unit experiencing a hardware failure, refer to the list of suggested solutions below.

A fan failure warning message is received

Your Switch has a fan monitoring system that will generate fan failure warning messages. Fan failure could potentially reduce the lifetime of the Switch. The monitoring system polls the fan status at periodic intervals while the unit is powered up.

If one fan has failed in the Switch, a warning message will be generated in the following ways:

■ Unit LED

The seven segment display will show a green flashing ‘f’.

■ RMON Trap

If configured, an RMON trap is generated and sent to the management workstation.

■ Command Line Interface

An indication of a general hardware failure is provided through the Top level menu displayed when logging on to the CLI. For more detailed information about the failure select the display logbuffer command.

■ Web interface

An indication of fan failure is provided through the Device Summary table for the specific unit. In addition all Summary tables turn red to indicate the fan failure.

56 CHAPTER 4: PROBLEM SOLVING

If a fan failure warning message is generated:

1 Power off the unit.

2 Check that the air vents are not obstructed.

3 Power cycle the unit. To do this, remove and reconnect the AC mains

supply. If another fan failure warning message is generated using the Command Line Interface or the Web interface, return the unit to 3Com.

Unit fails, no SNMP fan failure message is received

1 Power cycle the unit. To do this, remove and reconnect the AC mains

supply.

2 Check the command line interface (display logbuffer command)

to determine whether a thermal shutdown has occurred.

3 If no, return the unit:

If yes, check that:

■ The air vents are not obstructed.

■ The ambient temperatures and environmental conditions meet those

specified in Appendix C.

4 Power cycle the unit. If a further thermal shutdown occurs, and all

environmental conditions are satisfactory, return the unit to 3Com.

Error message indicating that the SFP transceiver is invalid

The Switch has identified that the SFP does not meet the minimum requirements for the Switch and has disabled the port. To correct this problem, completely remove the SFP and replace it with a 3Com approved SFP. See “Approved SFP Transceivers” on page 26.

Error message indicating that the SFP transceiver is faulty

To correct this problem, completely remove the SFP and then reinsert it. Alternatively, insert another identical SFP. If the problem persists, contact 3Com Technical Support.

Solving Communication Problems 57

Solving Communication Problems

If you experience communication problems with the Switch, ensure that:

■ The Switch IP address and Management VLAN ID has been

configured.

■ If the Switch is separated from your management application by a

router, ensure that the default gateway IP address within the Switch is the same as the IP address of the router.

■ The Switch’s IP address has been entered correctly in your network

management application (such as 3Com Network Director).

The following is a brief overview of IP addressing, and how to obtain a registered IP address.

IP Addressing

To be managed correctly, each device on your network (for example a Switch or Hub) must have a unique IP address. IP addresses have the format n.n.n.n where n is a decimal number between 0 and 255. An example IP address is 192.168.100.8.

The IP address is split into two parts:

■ The first part (‘192.168.100’ in the example) identifies the network on

which the device resides

■ The second part (‘.8’ in the example) identifies the device within the

network

The natural subnet mask for this example is 255.255.255.0.

If your network has a connection to the external IP network, that is, you access the Internet, you must apply for a registered IP address.

How do you obtain a registered IP Address?

The IP registration system ensures that every IP address used is unique; if you do not have a registered IP address, you may be using an identical address to someone else and your network will not operate correctly.

InterNIC Registration Services is the organization responsible for supplying registered IP addresses. The following contact information is correct at time of publication:

World Wide Web site: http://www.internic.net

58 CHAPTER 4: PROBLEM SOLVING

If your IP network is internal to your organization only, that is, you do not access the Internet, you may use any arbitrary IP address as long as it is not being used by another device on your network. 3Com suggests you use addresses in the range 192.168.0.0 to 192.168.255.255 with a subnet mask of 255.255.255.0.

These suggested IP addresses are part of a group of IP addresses that have been set aside specially for use ‘in house’ only.

5 UPGRADING SOFTWARE

This chapter describes how to upgrade the software in your Switch 4200G. It covers the following topics:

■ Upgrading from the Command Line Interface

■ Upgrading from the Bootrom Interface

■ Upgrading the Bootrom

Upgrade methods You can upgrade your Switch 4200G using several different methods:

■ Using the Command Line Interface is an easy and quick way. Either an

TFTP server or an FTP server can be used.

■ Upgrades can also be done through the boot menu using either TFTP,

FTP, or Xmodem. Xmodem is the slowest choice because it relies on the console’s serial port.

Note: If you need a TFTP or FTP server, we offer TFTP/FTP servers on www.3Com.com. Search for “tftp server”. The applications are located on the link to “3Com Software Library - Utilities for 32 bit Windows”. These applications run on Windows platforms.

60 CHAPTER 5: UPGRADING SOFTWARE

Upgrading from the Command Line Interface

Check Flash Space

Available

This section describes how to upgrade files to your Switch from the Command Line Interface (CLI).

The basic procedure is to check that you have enough space available in flash memory, backup your existing Switch software, and then upgrade the Switch software. The following sections describe these steps in detail.

Before upgrading the software to your Switch from the CLI, it is important to check the contents of the flash to ensure that there is enough space to download the new files.

The flash space needed for the new files is approximately 5.5 MB.

1 To check the contents of the flash, logon to your Switch either using a

telnet connection or directly using the console to display the User View in the CLI and enter the following:

<4200G> dir unit1>flash:

A file list similar to the following is displayed:

Directory of unit1>flash:/

1 (*) -rw- 4586799 Apr 06 2000 18:55:31 s3t03_01_00s56.app 2 (*) -rw- 890179 Apr 06 2000 18:56:51 s3v01_00.web 3 -rw- 296336 Apr 06 2000 19:01:23 s3u01_00.btm 4 -rw- 3333 Apr 02 2000 00:00:29 3comoscfg.def

15367 KB total (9582 KB free)

(*) -with main attribute (b) -with backup attribute (*b) -with both main and backup attribute

The file system listing may also contain files called topology.top and configuration files (file suffix .cfg).

2 Any additional files should be considered for deletion to allow maximum

space for downloading the new files. To delete a file from the list enter:

<4200G> delete/unreserved unit1>flash:/filename

CAUTION: Do not delete the topology.top file, or any configuration files (file suffix .cfg).

Upgrading from the Command Line Interface 61

3 The /unreserved option will cause the file to be deleted from both the

flash and the recycle-bin. To check that deleted files have been removed from the recycle-bin enter the following:

<4200G> reset recycle-bin unit1>flash:/

If the recycle-bin is empty the following is displayed:

% Recycle bin in this directory is empty

Backup Switch

Software

The following steps enable you to backup your Switch. (You can also backup these files to a TFTP or FTP server.)

1 To back up the default configuration file on your Switch, enter:

[4200G] copy unit1>flash:/3ComOScfg.def unit1>flash:/030100cfg.def
