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.
10/100/1000BASE-T The Switch 4200G has 12, 24 or 48 auto-negotiating
Ports 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.

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.
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

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.

Transceiver 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.
Choosing the
Correct Cables
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 All of the ports on the front of the Switch 4200G 28-Port are
Cables for the 100BASE-FX MT-RJ multi-mode ports. The MT-RJ port is a small form
Switch 4200G 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.

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.)
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.
Download from Www.Somanuals.com. All Manuals Search And Download.
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.
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 Once your Switch’s initial set up is complete you can set up your chosen
Management 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.
Manually
Configuring IP
Information
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).

CHAPTER 3: SETTING UP FOR MANAGEMENT
Setting Up SNMP
Management V1 or
V2
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.
Prerequisites
■
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 communitycommand. Refer to the
command line interface section of the “SuperStack 4 Switch Command
Reference Guide” for more information.
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 10.

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
If you experience communication problems with the Switch, ensure that:
Communication
Problems
■
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
Download from Www.Somanuals.com. All Manuals Search And Download.
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.

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.
