1SYSTEM AND SETUP OVERVIEW

This chapter contains:

■An overview of the CoreBuilder® 9400 system and

how it provides solutions for your network

■A description of the major features and

components of the system

■A network configuration example

CoreBuilder 9400 Intelligent Switch

The CoreBuilder 9400 system delivers full line rate

switching among all 24 Gigabit Ethernet ports. The

system has the following ports (shown in Figure 1 on

page 15):

■12 1000BASE-SX (MMF) ports with SC connectors

■12 GBIC ports that can accept 1000BASE-LX or

1000BASE-SX GBIC transceivers

The system supports full-duplex mode on all Gigabit

Ethernet ports and up to 32,000 MAC addresses. To

deliver even higher performance rates among

switches, the system supports trunking, which allows

you to group up to six Gigabit Ethernet ports into a

single multigigabit connection for a maximum of

12 trunks per system.

System Features and Benefits

The CoreBuilder 9400 is part of 3Com’s CoreBuilder

family. To combine technologies as your network

grows, install the CoreBuilder 9400 in your network.

Some key features of the CoreBuilder 9400 system:

■High-density Gigabit Ethernet configuration

This system exhibits no packet loss or delays even

under maximum network traffic on its 24 Gigabit

Ethernet ports.

■Trunking of Gigabit Ethernet ports

This system allows you to configure up to six

Gigabit Ethernet ports into a single multigigabit

connection for a maximum of 12 trunks per unit.

■Trunking links and Spanning Tree Protocol support

The CoreBuilder 9400 protects against cable and

equipment failures with Spanning Tree Protocol

and trunking links.

■Failure protection

To protect your network, this system has an

optional second power supply.

12 CHAPTER 1: SYSTEM AND SETUP OVERVIEW

■Resilient links

Resilient links technology protects your network

against an individual link or device failure by

providing a secondary backup link that is inactive

until it is needed.

■Manageability

The CoreBuilder 9400 provides full support for

VLANs and RMON-1, as well as a roving analysis

port through SNMP management.

System Management

The CoreBuilder 9400 system includes integrated

management to provide fault tolerance and

maximum network availability. This management is

accessible in three ways:

■CoreBuilder 9400 Administration Console

■Standard network management applications based

on SNMP, such as 3Com’s Transcend applications,

Sun’s SunNet Manager, HP’s OpenView, and IBM’s

NetView AIX applications

■Web Management suite of applications, with

forms for many management tasks, charts and

wizards to help you configure and monitor your

system, and online Help (separately installed) give

you instant information about your configuration

choices.

Network Configuration Example

This section discusses one way to place the

CoreBuilder 9400 in your network.

Speeding Up Server Access

To centralize your servers for easier service and

support, use a configuration like the one shown in

Figure 3.

Suppose that all of your organization’s servers are

located in that physical space. These servers must

support a large number of clients that are distributed

throughout the organization’s campus. The clients are

switched Fast Ethernet desktops.

First, you can multiplex the traffic from each group of

desktop clients into one higher-bandwidth stream

(trunk) through a SuperStack II Switch 3900.

Each SuperStack II 3900 can, in turn, pass its traffic

along to a CoreBuilder 9400, which multiplexes the

traffic into Gigabit Ethernet streams for the servers.

This architecture eliminates bottlenecks caused by

each Fast Ethernet device as it vies for access to the

server.

You can also use the CoreBuilder 9400 for many

other applications, such as to consolidate LAN

backbones or to provide more flexible trunking

configurations.

Cabling Gigabit Ethernet Ports

Before you cable the system, consider this Caution.

CAUTION: You may not want to connect the

network cables before you power on the system

(chapter 4) if you need to configure trunks, resilient

links, or the Spanning Tree Protocol (STP). To avoid

bridge loops, configure trunks, resilient links, and

STP using the Administration Console before you

connect the cables and after you power up the

system. See the Command Reference Guide and

the Implementation Guide for your system.

Guidelines for Gigabit Ethernet Cabling

For all Gigabit Ethernet cabling, keep the ports and

connectors free of dust. See “Cleaning Dirty Fiber

Optic Ports and Connectors” on page 40 for details.

Recommended Distances for

1000BASE-SX Ports or Transceivers

When you cable 1000BASE-SX ports or transceivers,

verify that the length of the fiber cable from the

system to any attached device does not exceed these

recommended distances:

■Use 62.5-micron MMF fiber with a modal

bandwidth specification of 160 MHz*km for

distances of up to 220 m (722 ft).

■Use 62.5-micron MMF fiber with a modal

bandwidth specification of 200 MHz*km for

distances of up to 275 m (902 ft).

■Use 50-micron MMF fiber with a modal bandwidth

specification of 400 MHz*km for distances of up

to 500 m (1645 ft).

■Use 50-micron MMF fiber with modal bandwidth

specification of 500 Mhz*km for distances of up to

550 m (1805 ft).

Recommended Distances for

1000BASE-LX Transceivers

When you cable 1000BASE-LX transceivers, verify

that the length of the fiber cable from the system to

any attached device does not exceed these

recommended distances:

■Use 62.5-micron MMF fiber with a modal

bandwidth specification of 160 MHz*km for

distances of up to 550 m (1805 ft).

■Use 62.5-micron MMF fiber with a modal

bandwidth specification of 200 MHz*km for

distances of up to 550 m (1805 ft).

■Use 50-micron MMF fiber with a modal bandwidth

specification of 400 MHz*km for distances of up

to 550 m (1805 ft).

■Use 50-micron MMF fiber with a modal bandwidth

specification of 500 MHz*km for distances of up

to 550 m (1805 ft).

■Use 9-micron SMF fiber for distances of up to

10 km (6.2 mi). The specification requires and

specifies 5 km (3.1 mi).

Use a conditioned launch cable to connect the

1000BASE-LX transceiver to multimode fiber. Using

this cable ensures reliability over the maximum 550 m

distance.

Cabling Gigabit Ethernet Ports 21

Cabling 1000BASE GBIC Ports

Each 1000BASE GBIC (Gigabit Interface Converter)

port accepts one of these transceivers:

■1000BASE-SX GBIC — Use this transceiver to

connect the GBIC port directly to multimode

fiber-optic cable. For instructions, see the

procedure in this section.

■1000BASE-LX GBIC — Use this transceiver to

connect the GBIC port directly to single-mode

fiber-optic cable or to multimode fiber using a

conditioned launch cable. For instructions on using

this transceiver to connect to single-mode fiber,

see the procedure in this section. To connect this

transceiver to multimode fiber, see “Connecting

the LX Transceiver to MMF” on page 24 for details.

To ensure optimal compatibility, performance, and

regulatory compliance, use only GBIC transceivers and

conditioned launch cables that 3Com supports. For a

list of currently supported GBICs and launch cables,

visit this 3Com Web site:

http://www.3Com.com/gigabit_ethernet/gbics

You can insert and remove the GBIC transceiver while

the system is powered on and running.

To connect a GBIC port directly to single-mode fiber

with an LX transceiver, or to connect a GBIC port

directly to multimode fiber with an SX transceiver,

follow these steps:

1Read and follow the “Fiber Safety Precautions” on

page 19 and the Caution at the beginning of

“Cabling Gigabit Ethernet Ports” earlier in this

chapter.

2Orient the transceiver so that the duplex SC

connector is toward you, as shown in Figure 6.

cannot insert it any further). Then move the front

lever to the downward position to lock the

transceiver into place.

4If you haven’t already done so, remove the SC

connector cover from the transceiver, as shown in

Figure 7.

Figure 7 Removing the SC Connector Cover

5Plug the male duplex SC connector on the fiber optic

network cable into the duplex SC port on the GBIC

transceiver, as shown in Figure 8. If you are using an

SX transceiver, the fiber optic cable must support

multimode transmission. If you are using an LX

transceiver, the fiber optic cable must support

single-mode transmission or multimode transmission

with a conditioned launch cable.

You can also connect an LX transceiver to multimode

fiber. See “Connecting the LX Transceiver to MMF” on

page 24 for details.

In the event that you need to remove the GBIC

transceiver, follow these steps, depending on the

transceiver that you are using:

■Side tabs — Compress the side tabs and gently

pull the transceiver out of the port.

6Attach the other end of the network fiber-optic cable

to the network device that you want to connect.

7Repeat steps 1 through 6 for additional GBIC ports.

Connecting the LX Transceiver to MMF

The LX transceiver supports a connection to

multimode fiber using a conditioned launch cable.

The conditioned launch cable consists of an offset

mechanism on the transmit side of the cable that

aligns the single-mode laser launch away from the

center of the multimode fiber core, creating a

transmission signal similar to typical multimode

light-emitting-diode (LED) launches. This offset allows

the transmission of LX signals over multimode fiber

cable.

You need a conditioned launch cable to complete the

following procedure. To ensure optimal compatibility,

performance, and regulatory compliance, use only

conditioned launch cables that 3Com supports. For a

list of currently supported launch cables, visit this

3Com Web site:

http://www.3Com.com/gigabit_ethernet/gbics

To cable a GBIC port to multimode fiber using an LX

transceiver:

1Read and follow the “Fiber Safety Precautions” on

page 19 and the Caution at the beginning of

“Cabling Gigabit Ethernet Ports” earlier in this

chapter.

2Insert a GBIC LX transceiver into a GBIC port until it

clicks into place, as shown in Figure 6.

Cabling the Console Port

The Console port provides access for either local or

remote administration.

For local administration of the CoreBuilder 9400, the

Console port provides an RS-232 connection to a

local terminal or workstation that runs a terminal

emulation program and acts as the console.

For remote administration, the Console port provides

the means to connect an external modem, which you

can use to establish a connection between your

current Administration Console session and the

modem port.

The Console port has a male 9-pin, D-type connector.

See “Console Port Pin Assignments” next for pin-out

information.

To cable the Console port:

1Attach the female DB-9 cable connector to the

Console port’s male connector. See Figure 10.

2Attach the other end of the serial cable to your

terminal or workstation.

You can also remotely access the system through any

Gigabit Ethernet port using Telnet. See the Command

Reference Guide.

To use the Administration Console to configure the

system for management access through the Console

port, see Chapter 5.

5QUICK SETUP FOR MANAGEMENT ACCESS

This chapter provides easy instructions for configuring

the CoreBuilder® 9400 system for management

access. When you decide how you want to manage

your system, follow the configuration instructions for

your preferred type of management access.

About CoreBuilder 9400 System Management

To configure and manage your CoreBuilder 9400

system, you can use one of several applications after

you establish a connection:

■CoreBuilder 9400 Administration Console

■Other SNMP-based network management

applications

■Web Management suite of applications

The Administration Console is a character-oriented,

menu-driven user interface for administering the

system. You can access the Administration Console

out-of-band, using either the 10BASE-TX port or the

Console port, or in-band, using one of the Gigabit

Ethernet ports through the IP network protocol. For

more detailed information, see the Command

Reference Guide.

For more complete network management, use an

external SNMP-based management application such

as 3Com’s Transcend Enterprise Manager for UNIX or

Windows or another network management

application.

The Web Management suite of applications allows

you manage your system using a Web browser. It

consists of WebConsole (including Configuration

Wizards), DeviceView, Performance, and the

HTML-based Help system.

How Do You Want to Manage the System?

You can manage your system locally through a

terminal connection or through the network with an

IP connection. Table 6 describes the access

mechanisms.

Terminal Connection

Direct access through the Console port is often

preferred because it allows you to remain on the

system during system boots. A Macintosh or PC

attachment can use any terminal emulation program

for connecting to the Console port. A workstation

attachment under UNIX can use the emulator TIP or

you can attach a terminal.

For more details, see the documentation that is

shipped with your terminal emulation program.

Tab l e 6 Management Access Mechanisms

Access

Mechanism Allows you to Using

Modem Connection

To access the system through a modem, establish a

connection between your workstation and the

Console port. When you configure the external

modem from the Administration Console menu

system, the Console appears to be directly connected

to the external modem. See the Command Reference

Guide for more information.

Use the Console port for either a terminal connection

or a modem connection.

IP Management Interface

An IP interface is the connection between the

CoreBuilder 9400 system and a subnetwork. Use the

IP interface to manage the system in two ways:

■In-band — Through a Gigabit Ethernet port

You can use this port for switching and managing

the system simultaneously.

This method decreases the total bandwidth available

on the port for switching.

■Out-of-band — Through the 10BASE-TX port that

is located to the left of the Console port

You can use this port only to manage the system,

not for switching network traffic. Managing your

system out-of-band conserves all available

bandwidth for the Gigabit Ethernet ports. Also, if

network problems exist, you can manage the

system from a different network. See the

Implementation Guide for more information on

in-band and out-of-band management.

Initial Management Access 35

With an IP interface and either the in-band or the

out-of-band port, you use the rlogin or Telnet

commands to access the Administration Console

using TCP/IP from a host computer. You can also use

the IP interface to manage the system with an

external management application via SNMP or the

Web Management software.

Initial Management Access

The first time that you access your system, you

connect through the Console port using a terminal or

terminal emulator. These are the default settings for

this port: 9600 baud, 8 bits, 1 stop bit, No parity.

When you access the Administration Console using

the Console port, you see this prompt:

Select access level (read, write, administer):

1At the prompt, enter:

administer

2At the password prompt, press Return.

The following menu appears:

Use this menu to change the Console port baud

setting for the terminal or to configure your system

for another management access mechanism.

Changing the Console Port Baud Setting

To change the baud setting of the Console port:

1From the top level of the Administration Console,

enter:

system serialPort serialPortMode

2At the prompt, if the default value shown in brackets

is modem, enter console. Otherwise, press Return.

3Enter baudRate.

4Enter 9600 for the Console port. The system supports

these baud settings: 19200, 9600, 4800, 2400, and

1200.

The system displays this message:

Enter new value (1200-19200) [1200]: 9600

Configuring the IP Interface

These instructions include information on how to

define an IP interface through which you can manage

your CoreBuilder 9400 system. An IP interface

contains the following parameters:

■IP address — This address, which is specific to

your network, is used to manage the system. The

IP address defines both the number of the network

to which the interface is attached and its host

number on that network.

■Subnet mask — This 32-bit number uses the

same format and representation as an IP address.

The subnet mask determines which bits in the IP

address are interpreted as the network number,

which as the subnet number, and which as the

host number. Each IP address bit that corresponds

to a 1 in the subnet mask is in the network and

subnet part of the address. Each IP address bit that

corresponds to a 0 is in the host part of the IP

address.

In-band Management

To set the IP interface parameters to manage the

system in-band:

1From the top level of the Administration Console,

enter:

ip interface define

2Enter the IP address of the interface.

3Enter the subnet mask of the subnetwork to which

the interface is to be connected.

4Enter the interface type: vlan

5Enter the VLAN interface index

For more detailed instructions on assigning interface

parameters, see the Command Reference Guide.

Out-of-band Management

To set the IP interface parameters to manage the

system out-of-band:

1From the top level of the Administration Console,

enter:

ip interface define

2Enter the IP address for the out-of-band port.

3Enter the subnet mask of the subnetwork to which

the interface is to be connected. Press Return to

accept the default subnet mask.

4Enter the interface type: system

For more detailed instructions on assigning interface

parameters, see the Command Reference Guide.

40 CHAPTER 6: TROUBLESHOOTING THE SYSTEM

Cleaning Dirty Fiber Optic Ports and

Connectors

Fiber optic transceivers are sensitive optical devices.

Handle them carefully. If dirt collects on a fiber optic

lens, the associated LED may not light. You may also

notice degradation in port performance, indicated by

adverse changes in the Gigabit Ethernet statistics on a

port.

To prevent dust from collecting on the fiber optic lens,

keep the dust covers on the ports at all times when

they are not in use.

WARNING: The fiber optic lasers used in this system

meet the regulatory requirements for casual exposure

to the eye. As with any source of bright light,

however, 3Com recommends that you do not look

into the laser light source.

To clean a fiber optic lens, take these steps:

1Remove any accumulated dust or debris from the port

or connector by blowing across all surfaces with a

canned air duster.

Compressed gas is recommended, such as

Chemtronics’ Ultrajet or the Triangle Tool Group’s

Liqui-Tool Dust-A-Way. Do not use commercial

compressed air or “house air” because of the risk of

oil contamination.

2Reconnect the cable to the port to check whether

dusting has corrected the problem.

3Gently wipe the ports with a lint-free, nonabrasive,

nonadhesive swab. Microswabs by Texwipe are

recommended.

4Gently wipe the connectors with a lint-free,

nonabrasive wipe or pad. Texwipe pads are

recommended.

Avoid touching any connector surface after you clean

the connectors.

BFIELD-REPLACEABLE UNITS

This appendix contains information on how to

remove and replace the CoreBuilder®9400

Field-Replaceable Units (FRUs). The FRUs include:

■Power supply assembly

■Fan tray assembly

Only trained technical personnel should remove and

install the power supply.

Audience

This appendix is intended for trained technical

personnel only. Do not attempt to remove or replace

a CoreBuilder 9400 power supply if you have not had

the proper training from 3Com. For training

information, call 1-800-NET-3COM or see the

numbers for your country in Appendix D.

WARNING: Hazardous energy exists within the

CoreBuilder 9400 system. Use extreme caution when

you remove or replace the FRUs. Always be careful to

avoid electric shock or equipment damage. See

“Safety Precautions” next.

Safety Precautions

Be sure that you follow all safety precautions when

you replace components in a CoreBuilder 9400

system. Hazardous energy exists inside the system

chassis. To avoid electric shocks, burns, or equipment

damage, read and following these warnings:

WARNING: Always unplug the power cord before

you open any electronics chassis box or enclosure.

When the system is on, do not touch any connections

within the chassis. Do not insert metal objects into

the system.

Power Supply Assembly Removal and

Replacement

The CoreBuilder 9400 system operates using a single

power supply assembly. You can add a second power

supply to the system for redundancy. If either power

supply fails, the Fault LED lights yellow.

Removing and Replacing the Power Supply

1Remove the power cord from the power supply.

2Loosen the captive screws that secure the power

supply to the chassis.

3Grasp the power supply handle and gently slide the

power supply out of the chassis.

44 APPENDIX B: FIELD-REPLACEABLE UNITS

4Grasp the handle of the new power supply and gently

slide it into the chassis.

5To seat the power supply, ensure that all connectors

are aligned. Then push the power supply inward until

the connectors engage and latch. The latch should

slide up. You feel a slight resistance as the connectors

engage.

CAUTION: If the resistance is too great, the

connectors may not be aligned. Forcing the power

supply inward could damage the connectors. If

necessary, remove and reinsert the power supply,

ensuring that the connectors are properly aligned.

6Tighten the captive screws that secure the power

supply to the chassis.

7Plug the power cord into the system.

8Plug the other end of the power cord into the

building’s power outlet.

If your system has two power supplies, be sure to

plug in the second power supply. Leaving the second

power supply unplugged causes the system

diagnostics to generate a power supply error.

Fan Tray Assembly Removal and Replacement 45

Fan Tray Assembly Removal and Replacement

The CoreBuilder 9400 is cooled by the fan tray

assembly, which contains two 12-volt DC fans. The

fans are thermally controlled, which means that they

run at slower speeds when the system is operating at

temperatures of less than 30 °C and at full speed

when the system temperature is above that.

You need no tools to remove the fan tray. You can

remove and replace the fan tray with the power on.

To remove and replace the fan tray assembly, follow

these steps:

1Facing the front of the system, squeeze the fan tray

latching tab.

2Slide the fan tray out of the system.

3Slide the new fan tray into the system chassis.

4To seat the fan tray, ensure that the connectors are

aligned, and then push the fan tray inward until the

connectors engage and the fan tray latches. You feel

a slight resistance as the connectors engage.

CAUTION: If the resistance is too great, the

connectors may not be aligned. Forcing the fan tray

inward could damage the connectors. If necessary,

remove and reinsert the fan tray, ensuring that the

connectors are properly aligned.

CSITE REQUIREMENTS AND SAFETY CODES

For your reference, this appendix summarizes the

criteria that your site should meet for the

CoreBuilder®9400 to operate safely and effectively.

The topics covered in this appendix:

■General Safety Requirements

■Wiring Closet Recommendations

■Distribution Rack Requirements, if you mount one

or more CoreBuilder 9400 systems in a distribution

rack

■Building and Electrical Codes

General Safety Requirements

For safe operation, your site must meet these general

safety requirements:

■Environmental requirements. See Appendix A and

“Wiring Closet Recommendations” for details. Pay

special attention to temperature and humidity.

■All building and electrical codes for your city and

country. See relevant “Building and Electrical

Codes” for more information.

■Grounding requirements. See “Wiring Closet

Recommendations” and “Distribution Rack

Requirements” for details.

Wiring Closet Recommendations

The cabling system plan at your facility probably

covers most wiring closet concerns. 3Com also

recommends that you check these items:

■Verify that your wiring closet meets all of the

requirements in your facility cabling plan.

■Verify that your wiring closet and your facility meet

all state, local, and country building and wiring

codes.

■Be sure that your system is easily accessible for

installation and service.

■Provide adequate overhead lighting for easy

maintenance.

■Be sure that all wiring closet doors have locks to

prevent unauthorized access.

■Assign wiring closet identification numbers using

architectural location codes or some type of

floor-grid matrix.

■Select a vinyl floor covering for your wiring closet.

Concrete floors accumulate dust; carpets can

cause static electricity.

■Be sure that the wiring closet floor is flat and level.

If you are using distribution racks and the floor is

not level, bolt the racks to the floor to prevent

them from tipping over.

48 APPENDIX C: SITE REQUIREMENTS AND SAFETY CODES

■Be sure that each wiring closet has a suitable

ground. Ground all metal racks, enclosures, boxes,

and raceways in the closet.

■Use AC power, 15-ampere service receptacles, type

N5/15 or NEMA 5-15R for 120 VAC, and the other

system specifications shown in Appendix A.

■Be especially sure to meet all system environmental

requirements in Appendix A, such as ambient

temperature and humidity.

■Be sure that the ventilation in the wiring closet is

adequate to maintain a temperature below 40 °C

(104 °F).

■Install a reliable air conditioning and ventilation

system if you plan to have two or more

CoreBuilder 9400 systems in a single wiring closet.

■To prevent overheating during nonbusiness hours,

guard against the ventilation being shut down

while a CoreBuilder 9400 system remains powered

up.

Distribution Rack Requirements

If you plan to mount your CoreBuilder 9400 system

in a distribution rack, verify that your rack meets the

basic mechanical and space requirements described in

this section.

Protective Grounding for the Rack

Proper distribution rack grounding ensures that

voltages induced into wiring by lightning or other

disturbances are directed to ground. Normally, you

use a distribution rack grounding kit and a ground

conductor that is carried back to earth or to another

suitable building ground. To order the grounding kit,

contact your sales representative.

Space Requirements for the Rack

Provide enough space in front of and behind the

system so that you can service it easily. Allow a

minimum of 76 cm (30 in.) between the rack and any

wall behind or in front of it. Extra room on each side

is optional. See Figure 15.

Install your distribution rack near an easily accessible

power outlet. You can power down the system only

by removing the power cord from the power source.

Distribution Rack Requirements 49

Figure 15 Recommended Service Access

Mechanical Requirements for the Rack

Verify that your racks comply with the standards and

requirements in your cabling system plan and

conform to these conventional standards:

■In the United States, comply with EIA Standard

RS-310C: Racks, Panels, and Associated

Equipment.

■In countries other than the United States, comply

with IEC Standard 297: Dimensions of Panels and

Racks.

In addition, 3Com recommends that your distribution

racks meet these requirements:

■Use an open style, 19-inch rack. The rack styles

shown in Figure 16 facilitate easy maintenance

and provide excellent ventilation.

■Use a rack that has the universal mounting rail hole

pattern identified in IEC Standard 297.

■Use a rack that is made of steel.

■Install equipment in the lower half of the

distribution rack to avoid making it top heavy.

■Use a rack that supports approximately 272 kg

(600 lb)

■Use a rack that has adequate electrical grounding,

for instance, with a distribution rack grounding kit.

■Verify that the floor under the rack is level within

5mm (

3

/16 in.). Use a floor-leveling cement

compound or bolt the racks to the floor.

■Attach the rack to the wiring closet floor with

9.5 mm (3

/8 in.) lag screws or equivalent hardware.

■Brace open distribution racks if the channel

thickness is less than 6.4 mm (1

/4 in.).

in substantial conformance to its program specifications, for a period of ninety (90) days

from the date of purchase from 3Com or its authorized reseller. 3Com warrants the

will be uninterrupted or error free, or that all defects in the software products will be

corrected. For any third-party products listed in the 3Com software product

documentation or specifications as being compatible, 3Com will make reasonable

efforts to provide compatibility, except where the noncompatibility is caused by a “bug”

or defect in the third party’s product or from use of the software product not in

accordance with 3Com’s published specifications or user manual.

THIS 3COM PRODUCT MAY INCLUDE OR BE BUNDLED WITH THIRD-PARTY SOFTWARE,

THE USE OF WHICH IS GOVERNED BY A SEPARATE END-USER LICENSE AGREEMENT.

THIS 3COM WARRANTY DOES NOT APPLY TO SUCH THIRD-PARTY SOFTWARE. FOR

THE APPLICABLE WARRANTY, PLEASE REFER TO THE END-USER LICENSE AGREEMENT

GOVERNING THE USE OF SUCH SOFTWARE.

In addition to the Hardware Warranty and Software Warranty stated above, 3Com

warrants that each product sold or licensed to Customer on and after January 1, 1998,

exhibits a defect in materials or workmanship within the first forty-eight (48) hours of

installation but no later than thirty (30) days after the date of purchase, and this is

verified by 3Com, it will be considered dead- or defective-on-arrival (DOA) and a

replacement shall be provided by advance replacement. The replacement product will

normally be shipped not later than three (3) business days after 3Com’s verification of

the DOA product, but may be delayed due to export or import procedures. The

shipment of advance replacement products is subject to local legal requirements and

replacement is provided and Customer fails to return the original product to 3Com

within fifteen (15) days after shipment of the replacement, 3Com will charge Customer

for the replacement, at list price. This advance replacement is different from the

AND ARE IN LIEU OF ALL OTHER WARRANTIES, TERMS, OR CONDITIONS, EXPRESS OR

IMPLIED, EITHER IN FACT OR BY OPERATION OF LAW, STATUTORY OR OTHERWISE,

INCLUDING WARRANTIES, TERMS, OR CONDITIONS OF MERCHANTABILITY, FITNESS

FOR A PARTICULAR PURPOSE, SATISFACTORY QUALITY, CORRESPONDENCE WITH

DESCRIPTION, AND NONINFRINGEMENT, ALL OF WHICH ARE EXPRESSLY DISCLAIMED.

3COM NEITHER ASSUMES NOR AUTHORIZES ANY OTHER PERSON TO ASSUME FOR IT

ANY OTHER LIABILITY IN CONNECTION WITH THE SALE, INSTALLATION,

MAINTENANCE, OR USE OF ITS PRODUCTS.

ATTEMPTS TO OPEN, REPAIR, OR MODIFY THE PRODUCT, OR ANY OTHER CAUSE

BEYOND THE RANGE OF THE INTENDED USE, OR BY ACCIDENT, FIRE, LIGHTNING,

POWER CUTS OR OUTAGES, OTHER HAZARDS, OR ACTS OF GOD.

LIMITATION OF LIABILITY

TO THE FULL EXTENT ALLOWED BY LAW, 3COM ALSO EXCLUDES FOR ITSELF AND ITS

SUPPLIERS ANY LIABILITY, WHETHER BASED IN CONTRACT OR TORT (INCLUDING

NEGLIGENCE), FOR INCIDENTAL, CONSEQUENTIAL, INDIRECT, SPECIAL, OR PUNITIVE

DAMAGES OF ANY KIND, OR FOR LOSS OF REVENUE OR PROFITS, LOSS OF BUSINESS,

LOSS OF INFORMATION OR DATA, OR OTHER FINANCIAL LOSS ARISING OUT OF OR IN

CONNECTION WITH THE SALE, INSTALLATION, MAINTENANCE, USE, PERFORMANCE,

FAILURE, OR INTERRUPTION OF ITS PRODUCTS, EVEN IF 3COM OR ITS AUTHORIZED

RESELLER HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES, AND LIMITS ITS

LIABILITY TO REPAIR, REPLACEMENT, OR REFUND OF THE PURCHASE PRICE PAID, AT

3COM’S OPTION. THIS DISCLAIMER OF LIABILITY FOR DAMAGES WILL NOT BE

AFFECTED IF ANY REMEDY PROVIDED HEREIN SHALL FAIL OF ITS ESSENTIAL PURPOSE.

DISCLAIMER

Some countries, states, or provinces do not allow the exclusion or limitation of implied

warranties or the limitation of incidental or consequential damages for certain products

supplied to consumers, or the limitation of liability for personal injury, so the above

limitations and exclusions may be limited in their application to you. When the implied

warranties are not allowed to be excluded in their entirety, they will be limited to the

duration of the applicable written warranty. This warranty gives you specific legal rights

which may vary depending on local law.

This Limited Warranty shall be governed by the laws of the State of California, U.S.A.,

excluding its conflicts of laws principles and excluding the United Nations Convention

on Contracts for the International Sale of Goods.
