Mounting the Switch on a Desktop

In many cases, standard 19-inch racks are not available. Therefore, switches are
often placed on a desktop. To place your switch on a desktop, you simply need to:

■ Make sure that the surface is clean, flat, and sturdy.

■ Makes sure that the environment is well ventilated and allow 10 cm (3.9 in.) of

space around the chassis for heat dissipation.

■ Do not place heavy objects on your switch.

■ When stacking, the vertical distance between two switches must be at least 1.5

cm (0.59 in).

Figure 22 Power socket (recommended)

Connecting the AC Power Cord

1 Connect one end of the chassis ground wire to the grounding screw on the rear of

the chassis and the other end to the ground as near as possible.

2 Connect one end of the power cord to the power input on the rear panel of the

chassis, and plug the other end to the AC power input of the power source.

3 Check whether the PWR LED on the front panel of the switch is ON. If the LED is

ON, it shows the power cord is properly connected.

CAUTION: Make sure that the ground wire has been properly connected before
powering on the switch.

Connecting the Ground

Wire

CAUTION: Correctly connecting the switch ground wire is crucial to the lightning
protection and electromagnetic susceptibility (EMS) of your switch.

The power input end of the switch is connected with a noise filter, whose central
ground is directly connected to the chassis, forming the chassis ground (commonly
known as PGND). This chassis ground must be securely connected to the earth
ground so that the faradic current and leaking electricity can be safely released to
the ground, enhancing the EMS capability of the switch. Ground your switch as
follows:

1 When a grounding strip is available at the installation site, attach one end of the

yellow/green ground wire of the switch to the grounding screw on the grounding
strip and fasten the captive nut.

Note: The fire main and lightning rod of a building are not suitable for grounding
the switch. The ground wire of the switch should be connected to the grounding
device for the equipment room.

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:

■ Methods of Managing a Switch

■ Setting Up Command Line Interface Management using SSH

■ Setting Up Web Interface Management

■ Setting Up SNMP Management

■ Default Users and Passwords

■ For information on the lost password procedure please refer to the

Configuration Guide that is supplied with your switch.

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 27), or remotely over the network (see Figure 28).

■ 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
<4210>.

■ 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 [4210].

The Switch 4210 supports Secure Shell version 2.0 (SSHv2.0), 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 29).

IP Configuration In order for the device to be remotely managed, it requires an IP address. You can

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 44.

use one of the following methods to allocate IP information to your switch.

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.

Setting Up Overview 33

For a detailed description of how automatic IP configuration operates, please refer
to the Configuration Guide on the 3Com Web Site.

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.

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 assign a known IP address to
your switch. 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 36.

34 CHAPTER 3: SETTING UP FOR MANAGEMENT

Viewing Automatically Configured IP Information

Connecting to the

Console Port

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 using:

■ 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).

■ Network Director or 3Com Network Supervisor

These applications will auto-discover the switch and display the automatically
allocated IP information assigned to the switch.

■ Reviewing information in your DHCP Server

The DHCP server in your network may log IP address assignments. Reviewing
this log, you may be able to determine the device's IP address. Refer to your
DHCP Server documentation for details.

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 36.

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, <4210> is
displayed as shown in the example in Figure 32.

Viewing Automatically Configured IP Information 35

Figure 32 User View Login

4 Enter display ip interface br to view a summary of allocated IP

addresses.

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 29.

If you do not intend to use the command line interface using the console port to
manage the switch, you can logout, disconnect the serial cable and close the
terminal emulator software.

Using 3Com Network

Director or 3Com

Network Supervisor

3Com has two management applications that will discover and help you manage
your network. 3Com Network Supervisor is freely distributed PC software ideal
for monitoring your network. It will discover your devices and connections, alert
you to network or configuration issues, assist you in registering your devices, and
proactively monitor the health of your network. 3Com Network Director is
chargeable PC software that adds advanced configuration and control to the
features available from 3Com Network Supervisor. Trial versions of both are
available from www.3com.com.

You can use 3Com Network Supervisor or 3Com Network Director applications to
discover the automatically allocated IP information.

1 Connect your switch to the network.

2 Launch 3Com Network Director or Network Supervisor and run the auto-discovery

wizard.

The application will auto-discover the new switch and display the IP information
that has been automatically allocated to the switch.

3 Power-up the switch and wait for two minutes.

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 Supervisor or 3Com Network Director must be on the same subnet
as the switch, because Auto-IP addresses are non-routable.

Manually Configuring IP Information

Connecting to the

Console Port

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). This is the only way to assign an IP address to a device that does not have
an IP address already, or that has an unknown IP address. You can also use this
method to change switch IP information.

■ 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). This is only applicable if the device already
has an IP address and you know that address.

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 while the switch is offline (before you connect
the switch to a network) or while the switch is online (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 “Pin-outs” on page 71.

■ 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

1 Connect the workstation to the console port using the console cable as shown in

Figure 33.

ip address xxx.xxx.xxx.xxx mmm.mmm.mmm.mmm

and Enter.

(where xxx.xxx.xxx.xxx is the IP address and mmm.mmm.mmm.mmm is the subnet
mask of the switch)

5 Select the quit command and enter the default gateway for the switch:

ip route-static 0.0.0.0 0.0.0.0 xxx.xxx.xxx.xxx

(where xxx.xxx.xxx.xxx is the IP address of the default gateway)

6 From the User View, enter the save command to save the configuration 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 29.

If you do not intend to use the command line interface using the console port to
manage the switch, you can disconnect the serial cable and close the terminal

Setting Up Command
Line Interface

This section describes how you can set up command line interface management
using a local console port connection or over the network.

Management

User Interface Overview User interface configuration is provided by the switch to configure and manage

the port data. There are two types of user interfaces:

■ AUX User Interface—used to log in to your switch using the console port. A

fabric can have up to eight AUX user interfaces.

CLI Management using

the Console Port

■ VTY User Interface—used to Telnet to the switch. The switch can have up to

five VTY user interfaces.

To manage a switch using the command line interface using the local console port
connection:

1 Ensure you have connected your workstation to the console port correctly as

described in “Connecting to the Console Port” on page 36.

2 Your switch is now ready to continue being managed and/or configured through

the CLI using its console port.

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 Supervisor or 3Com Network Director application
that is available from the 3Com website to provide SNMP management for your

44 CHAPTER 3: SETTING UP FOR MANAGEMENT

switch. If you use 3Com Network Director it automatically loads the correct MIBs
and necessary files onto your workstation.

Prerequisites

■ Documentation supplied with the SNMP network management application

software.

■ The default read community string is public. The default write community

string is private.

■ To display the current configuration of the community strings in the System

View, enter display snmp-agent community.

(new community string up to 32 characters).

■ To configure new write community strings, enter snmp community write

(new community string up to 32 characters).

■ To remove a community string, enter undo snmp-agent community (the

string to be removed).

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.

These switches support SNMP V1, V2, and V3. SNMP V3 is on as default. All
commands are in snmp menu in System View.

Default Users and Passwords

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 15.

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.

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 4210 Command Reference Guide on the CD-ROM
that accompanies your switch.

For Technical Support information, see “Obtaining Support for Your 3Com
Products” on page 73.

48 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. Check the power cord by:

■ Testing it in another device.

■ Connecting a working power cord to the ‘problem’ device and 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.

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 49

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.

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 “Technical Specifications” on page 73.

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

conditions are satisfactory, return the unit to 3Com.

50 CHAPTER 4: PROBLEM SOLVING

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.

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

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

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

Solving Fabric Formation Problems 51

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.

Solving Fabric Formation Problems

If you are having problems with correctly forming a fabric, first ensure that
Spanning Tree is enabled. If it is enabled, do the following:

1 Power off all units in the fabric.

2 Check all the cable connections in the fabric.

3 Check the ports have been enabled as fabric ports.

4 Power on all units in the fabric.

52 CHAPTER 4: PROBLEM SOLVING

UPGRADING SOFTWARE

5

This section describes how to upgrade the software in your Switch 4210. It covers
the following topics:

■ Upgrade Options

■ Contents of the Installation File

■ Upgrading from the Command Line Interface

■ Configuring the Boot Loader and Updating the Boot ROM Using the CLI

■ Upgrading from the Boot ROM Menu

■ Configuring the Boot Loader Using the Boot Menu

Upgrade Options You can upgrade your Switch 4210 using the:

■ Command Line Interface with either an TFTP server or an FTP server. This is the

fastest method.

■ Switch’s Boot Menu with 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, you can use the 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.

54 CHAPTER 5: UPGRADING SOFTWARE

Contents of the Installation File

Upgrading from the Command Line Interface

When you download the Switch 4210 software from the 3Com Web site, you
receive a self-extracting executable file named s3q05_01_00s56.exe or
s3q05_01_00s168.exe. This installation file contains the following:

■ End User License (license.txt)

■ Release Notes (readme.pdf)

■ Application Software (.app)

■ Boot ROM Software (.btm)

■ Bundled file used with 3Com Network Director upgrade wizard. For example,

s3q05_01_00s56NetMan.zip.

CAUTION: Use the bundled files with the extension NetMan.zip only to upgrade
your Switch using the 3Com Network Director Agent Update. Do not attempt to:

■ Upgrade individual .btm or .app files using 3Com Network Director. Use these

files only to upgrade your switch with the CLI or the Boot ROM interface.

■ Upgrade the switch with .exe or NetMan.zip using the CLI or Boot ROM

interface. Use these files only to upgrade your switch with 3Com Network
Director Agent Update.

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.

Confirming the FTP or

TFTP Connection

Checking the Available

Flash Space

Before upgrading your switch, you should:

■ Verify that there is a connection between the FTP or TFTP server and the

Switch 4210 (you can use the ping command to confirm the connection).

■ Verify that the FTP or the TFTP server is set up according to the manufacturer's

instructions and that it is enabled and pointing to the correct upload/download
directory.

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 3.3 MB. The size of the
flash storage is approximately 8 MB.

1 To check the contents of the flash, log on to your switch either using a telnet

connection or directly using the console to display the User View. Using the CLI,
enter:

<4210> dir

A file list similar to the following displays:

Directory of flash:/

Upgrading from the Command Line Interface 55

0 -rw- 5213253 Apr 27 2000 12:49:41 s3q05_01_00s56c05.app

15240 KB total (10145 KB free)

The file system listing may also contain files called topology.top, configuration files
(file suffix .def), and Boot ROM file (suffix .btm).

2 Delete any additional files to acquire the maximum space for downloading the

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

<4210> delete/unreserved flash:/filename

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

The /unreserved option causes the file to be deleted from both the flash and
the recycle-bin. This may take several minutes depending on the size of the file
being deleted.

3 Check that deleted files have been removed from the recycle-bin by entering the

following:

<4210> reset recycle-bin flash:/

Backing up the Switch

Software

A prompt displays for every file in the recycle-bin. Answer Y to remove the file
from the recycle bin.

If you do not want to verify the files for deletion, use the command.

<4210> reset recycle-bin flash:/ /force

Answer Y to the “Clear files in recycle-bin directly?[Y/N]:” prompt.

This may take minutes depending on how big the contents of the recycle-bin are.
If there are not files in the recycle-bin the following message displays:

Recycle bin in this directory is empty

The following sections describe how to backup the files on your switch, including:

■ Backing up the Configuration Files

■ Backing up the Application Files

■ Backing up the Boot ROM File

You can save the flash:/ file system to an external TFTP, FTP, or SFTP server; or to the
flash:/ on the switch. If there is not enough free space available on the flash:/, or
you prefer to keep a separate backup copy of the files, save the files to an external
TFTP, FTP, or SFTP server.

Note: The names of the files on your switch will most likely differ from the names
used in the examples provided in the following sections.

Backing up the Configuration Files

If you are backing up a new Switch 4210 for which the configuration has never
been saved, a .def file does yet not exist. The first time you save a configuration,

56 CHAPTER 5: UPGRADING SOFTWARE

you are prompted for a file name. If you do not enter a filename, the file name
defaults to 3comoscfg-nPort.def (where n is the number of ports in the device,
eigther 9, 18, or 26). You can save a configuration file using any name, provided it
ends with the extension .def. 3Com recommends that you give each of your
switches a unique configuration file name so that the unit to which it belongs is
clear.

To back up the configuration files, perform the following step:

1 Save your switch configuration (.def file) by entering the

save command. The

following prompt displays:

The current configuration will be written to the device.
Are you sure?[Y/N]:

2 Ty pe Y and press Enter. The following prompt displays:

Please input the file name(*.def)[flash:/3comoscfg-nPort.def] (To
leave the existing filename unchanged, press the enter key):

3 Press Enter to accept the default filename (3comoscfg-nPort.def), or type a

different name and then press Enter. The following prompt displays:

Validating file. Please wait...
Now saving current configuration to the device.
Saving configuration flash:/3comoscfg-nPort.def. Please wait...
..
Configuration is saved to flash successfully.

4 View the contents of the flash:/ directory by entering the dir command. A list

similar to the following displays.

Directory of flash:/

15240 KB total (10137 KB free)

5 You can back up the configuration file to the switch’s flash:/ file or to a TFTP server:

■ To back up the default configuration file to the switch’s flash:/ file system,

enter:

copy flash:/3comoscfg-nPort.def flash:/Sw4210.def

The following prompt displays:

Copy flash:/3comoscfg-nPort.def to flash:/sw4210.def?[Y/N]:

Ty pe Y and press Enter. The following prompt displays:

%Copy file flash:/3comoscfg-nPort.def to flash:/sw4210.def...Done.

■ To save the active configuration file to a TFTP server, in User View enter:

tftp (TFTP server IP address) put flash:/(configuration filename)

For example, tp back up the configuration file from flash:/ to an TFTP server
with the IP address 10.0.1.100, enter

flash:/3comoscfg-nPort.def

tftp 10.0.1.100 put

(your TFTP servers IP address is most likely

different). The following messages display:

Backing up the Application Files

You can back up the application files to the switch’s flash:/ file system or to a TFTP
server.

■ To back up the application file to the switch’s flash:/ file system, enter:

copy flash:/s3q05_01_00s56.app flash:/s3q05_01_00s56app.app

■ To back up the application file to a TFTP server, enter the following command:

tftp (TFTP server IP address) put flash:/(filename).app

For example, to back up the application file from flash:/ to an TFTP server with
the IP address is 10.0.1.100 (your TFTP servers IP address will probably be
different), enter the following command:

tftp 10.0.1.100 put flash:/s3q05_01_00s56c05.app.

The following messages display:

File uploaded successfully.

Upgrading the Software

Using TFTP

This takes approximately four minutes with no traffic on the switch.

Backing up the Boot ROM File

You can back up the boot ROM file to the switch’s flash:/ file system or to a TFTP
server:

■ To back up the boot ROM file to the switch’s flash:/ file system, enter:

copy flash:/s3r01_15.btm flash:/s3r01_15boot.btm

■ To back up the boot ROM file to a TFTP server, enter:

tftp (TFTP server IP address) put flash:/(boot ROM filename).btm

To upgrade software for your Switch using TFTP:

1 Make sure the Switch can connect to the TFTP server by pinging the server.

2 Download the application file by entering:

tftp aaa.aaa.aaa.aaa get s3q05_01_00s56.app

(where aaa.aaa.aaa.aaa is the IP address of the TFTP server and s3q is the name
of the file you wish to download as described in Table 16.)

3 Download the Boot ROM file, by entering:

58 CHAPTER 5: UPGRADING SOFTWARE

tftp aaa.aaa.aaa.aaa get s3r01_15.btm

Some upgrades do not require an upgrade to the Boot ROM firmware, therefore
there may not be a new Boot ROM (.btm) file to download.

To display the Boot ROM firmware version, in any view enter:

display version

The switch returns the following:

Bootrom Version is 115

the Boot Loader and Updating the Boot ROM Using the CLI” on page 60 for
instructions.

Configuring the Boot Loader and Updating the Boot ROM Using the CLI

This section describes how to configure the switch to use the new .app file and
update the Boot ROM that you just loaded using the CLI. Perform the following
steps:

1 Set the switch to boot from the new application code (.app file) by typing the

following command (your .app filename maybe different):

boot-loader file flash:/s3q05_01_00s56.app main

2 Answer y to the prompt.

Example:

<4210>boot-loader file flash:/s3q05_01_00s56.app main
This command will set boot file, Continue? [Y/N]:y
The specified file will be used as a main boot file at the
next time!
<4210>dis boot-loader
The current boot app is: flash:/s3q05_01_00s56c05.app
The main boot app is: flash:/s3q05_01_00s56.app
The backup boot app is: NULL

The main boot app file is the file that the Switch 4210 will load next time the
switch is rebooted.

3 Update the new boot ROM firmware, by entering the following command:

bootrom update file flash:/s3r01_15.btm

4 Answer y to the prompt.

Example:

<4210>bootrom update file flash:/s3r01_15.btm
This command will update bootrom file, Continue? [Y/N]y
Now updating bootrom, please wait...

<4210>

5 Save any configuration made to the switch by entering the save command.

Example:

<4210>save
The current configuration will be written to the device.
Are you sure?[Y/N]:y

Configuring the Boot Loader and Updating the Boot ROM Using the CLI 61

Please input the file name(*.def)[flash:/3comoscfg-nPort.def](To

6 Reboot the switch to load the new boot ROM and application code. The Switch

4210 boots from the specified application (.app) file and configuration file (.def)
as displayed in the display boot-loader and display startup commands.

Once you have completed the upgrade, you can delete the files you saved during
the upgrade process.

The current application file is s3q05_01_00s56.app
(*)-with main attribute
(b)-with backup attribute

This option list also indicates the file from which the switch is currently set to boot
(as indicated with the attributes). The files that are required by the switch include:

■ s3r01_15.btm

■ s3q05_01_00s56.app

The s3r01_15.btm file is the boot software. The s3q05_01_00s56.app file is the
application software. The names of these files vary depending on the switch type
and the release version.

3Com Network Director

3Com Network Access Manager

3Com Network Director (3ND) is a standalone application that allows you
to carry out key management and administrative tasks on midsized
networks. By using 3ND you can discover, map, and monitor all your
3Com devices on the network. It simplifies tasks such as backup and
restore for 3Com device configurations as well as firmware and agent
upgrades. 3ND makes it easy to roll out network-wide configuration
changes with its intelligent VLAN configuration tools and the powerful
template based configuration tools. Detailed statistical monitoring and
historical reporting give you visibility into how your network is
performing.

To find out more about how 3Com Network Director can help you
manage your 3Com network and to download a trial version, go to:

www.3com.com/3nd

3Com Network Access Manager is installed seamlessly into Microsoft
Active Directory and Internet Authentication Service (IAS). It simplifies the
task of securing the network perimeter by allowing the administrator to
easily control network access directly from the “Users and Computers”
console in Microsoft Active Directory. With a single click, a user (or even
an entire department) can be moved to a different VLAN, or a computer
can be blocked from connecting to the network.

3Com Network Access Manager leverages the advanced desktop security
capabilities of 3Com switches and wireless access points (using IEEE

802.1X or RADA desktop authentication) to control both user and
computer access to the network.
