INTRODUCING THE ROUTER 3000 DSL

FAMILY

Introduction The 3Com Router 3000 DSL Family products are oriented for SOHO (small

office/home office) subscribers.

The 3000 DSL Family provides ADSL ports, G.SHDSL ports and/or ISDN ports. With

one or two subscriber lines, subscribers can be connected to CO (Central Office)

for broadband Internet access. The ISDN port is often used as backup port, but it

can also serve as an uplink port when the ADSL or G.SHDSL port fails. In

downstream direction, they provide four 10/100BASE-T Ethernet ports. Data

switching between them is Layer 2 (L2) switching, which supports port isolating.

With the ports compliant with the international standards. The Router 3000 DSL

Family products can interoperate with the products of other manufacturers on all

levels.

LED Description

INSTALLING THE ROUTER

General Site

Requirements

To ensure the proper working of the routers, and to prolong their service life, the

installation site should meet the requirements described in the following

subsections.

Requirements on

Environment

3000 DSL Family must be used indoors. To ensure the normal operation and

prolong their service life, the following requirements for installation site must be

met.

Requirements on

Temperature/Humidity

Certain requirements on temperature and humidity in the equipment room shall

be met. If the relative humidity is too high, the insulation materials in it will

deteriorate easily or even lead to electric leakage. Sometimes this will result in a

change of the mechanical performance of the materials, and rusting of the metal

components. If the relative humidity is too low, the fastening screw will loosen due

to shrinkage of the isolation spacer. In an environment with a dry climate static

electricity may be produced, putting the CMOS of the router to risk. High

temperature is of the greatest risks, for it will significantly degrade the router’s

reliability, speed up the aging process of the insulating materials, and shorten the

service life of the router. Below are the requirements on the temperature and

humidity for 3000 DSL Family:

Cleanliness

Requirements

Dust undermines the normal operation of 3000 DSL Family. Dust on the

equipment can cause electrostatic adsorption, which degrades the contact

performance of the metal connectors or connection points. This happens more

frequently when the indoor humidity is low, which will not only shorten the

router’s service life, but also cause communication failure.

Below is the recommended specification on dust content and particle diameter in

the equipment room:

Table 1 Humidity requirements in the equipment room

C to 40

C 10% to 90%

)

0.5 1.4 x 10

1 7 x 10

3 2.4 x 10

5 1.3 x 10

22 CHAPTER 3: INSTALLING THE ROUTER

The routers also have rigorous demands on the content of salts, acids and sulfides

in the air. These harmful gases will speed up the aging processes of certain parts

and cause a more rapid rusting of the metal parts. The equipment room should be

protected from the invasion of harmful gases such as SO2, H2S, NO2, NH3, and

Cl2, the value limits of which are shown below:

ESD Preventative

Requirements

Although many anti-static considerations have been given to 3000 DSL Family,

damage to the router’s circuit or even the whole equipment is still posible when

the static electricity exceeds the tolerance threshold.

In the communication network to which the routers are connected, static

induction mainly comes from:

■ External electric fields such as outdoor high voltage power lines or thunder.

■ Internal environment like flooring materials or the whole equipment

structure.

Lightning Protection

Requirements

Many measures have been taken to protect 3000 DSL Family from lightning.

However, if the lightning intensity exceeds a certain range, damage to the router is

still possible. To better protect the router from lightning, the following should be

considered:

■ Ensure the PGND wire of the chassis is well grounded.

■ Ensure the ground point of the socket of AC power supply is well grounded.

■ To enhance the lightning protection capability of the power supply, a

lightning arrester could be installed at the input end of the power supply.

■ As for the signal line outdoors to which the interface modules of 3000 DSL

Family routers are connected, such as ISDN line, telephone line, T1 line, etc,

a special lightning arrester should be installed at the input end of the signal

line to enhance the lightning protection capability.

Configuration

Fundamentals of the

Router

In general, the configuration steps are as follows:

1 Before configuring a router, you should make the networking requirements clear

and specific, including networking purpose, the role of the router in the network,

division of subnets, WAN type and transmission medium, network security policy

and reliability.

2 Draw a clear and integrated networking diagram.

3 Configure the IP addresses or IPX network numbers of all the interfaces on the

router on the basis of subnet division.

4 Configure the routes. If it is necessary to start the dynamic routing protocol, you

should also configure the related operating parameters for the protocol.

30 CHAPTER 4: CONFIGURING THE ROUTER

5 If security is required, perform the security configuration for the router.

6 If reliability is required, perform the reliability configuration for the router.

Although this devices has 4 physical ports it has only a single logical ethernet

interface, Ethernet1/0.

Command Line Interface The command line interface of 3Com Router 3000 DSL has a number of

configuration commands, which can be used to configure and manage the

routers. The command line interface has the following characteristics:

■ Performing local configuration through CON port.

■ Performing local or remote configuration through the Telnet command,

which can be used to directly log on and manage other routers.

■ Configuring the hierarchical user protection (includes guest, operator,

administrator). Only administrator users are authorized to configure and

manage the routers, so that unauthorized users would not be able to

invade the router illegally.

■ Users can enter <?> at any time to get online help.

■ Providing network diagnostic tools, such as Tracert and Ping, to quickly

diagnose the accessibility of the network.

■ Providing all kinds of detailed debugging information to diagnose network

faults.

■ The command line interpreter adopts fuzzy search for the keywords of the

command. Thus, you only need to enter the conflict-free keyword for the

interpretation of a command. For example, for the interpretation of a

display command, you can just input ”dis”.

The command line interface of 3Com Router 3000 DSL provides plenty of

configuration commands. Hierarchical user protection is adopted to prevent

unauthorized users from intruding.

In the system view, to facilitate the router management, all the commands are

grouped. Each group associates with a view. Users can use these commands to

switch between different configuration views. Normally, only certain commands

can be executed under a certain configuration mode, but some commands in

common use (such as ping, display current-configuration, and interface) can be

executed in all views.

SNMP Management

For help managing routers on your network, you can use 3Com Network Director

software to discover, map, and display network links and IP devices.

To allow Network Director to monitor your routers, you must first configure SNMP

V1 and SNMP Trap support with the following commands:

[3Com] snmp-agent sys-info version v1

[3Com] snmp-agent community read <read-community-string>

[3Com] snmp-agent community write <write-community-string>

[3Com] snmp-agent trap enable

In this example, <addr> is the address of the PC on which you have installed

Network Director.

SOFTWARE MAINTENANCE

Software The files managed by the router are of 3 types:

■ Boot ROM file

■ Application file (main software)

■ Configuration file

The router software maintenance mainly refers to the maintenance of those three

types of files, including upgrade and download of Boot ROM and application files,

as well as upload and download of configuration file.

Boot Menu This section introduces the Boot menu, which is used during the software

maintenance of a router.

Set up configuration environment in accordance with Figure 4.1 Local

configuration through CON port, and then start the router. When the

configuration terminal prompts the information “Press Ctrl-B to enter Boot

Menu”, press <Ctrl+B>. Then the system prompts the information:

Please input Boot ROM password:

Press <Ctrl+B> quickly as the prompt “Press Ctrl-B to Enter Boot Menu...” appears

and enter the Boot menu. Otherwise, the program decompression process will

begin.

To enter the Boot menu after the router starts the program decompression

process, reboot the router.

Enter the correct password, then press <Enter> (if no Boot ROM password has

been set, just press <Enter>), and the system will enter the Boot menu. The

following information will be displayed:
