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.

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:

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.
The following should be considered to safeguard the equipment against the ESD:
Make sure that the equipment and the floor are well grounded.
Make sure that dust-proof measures are taken.
Maintain an appropriate humidity and temperature.
Wear an ESD-preventive wrist strap and uniform when contacting the circuit
board.
Place the uninstalled circuit board on the antistatic workbench, with its face
upward, or put it into the static shielding bag.
When observing or removing the uninstalled circuit board, please touch the
edge of the circuit board, and avoid contacting the devices on it.
Electromagnetic
Environment
Requirements
The interference sources, no matter where they come from, affect the routers with
capacitance coupling, inductance coupling, radiation of electromagnetic wave,
common impedance (including the grounding system) or conducting line (power
line, signal line and transmission line etc.). The following should be considered:
Take effective measures to prevent the power system from being interfered
with by the power grid system.
Keep the router far away from the radio launcher, radar launcher, and
high-frequency devices working in high currents.
Use electromagnetic shielding when necessary.

Precautions 23
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.
Table Mount
Requirements
There is spacing reserved at the air inlet and outlet in the router so as to
facilitate the radiation of the router cabinet.
The workbenches have good radiation systems.
The workbenches are firm enough to support the weight of the router and
other installation accessories.
The workbench are well grounded.
Precautions Routers play a key role in data communications network. Please pay attention to
the following:
It indicates that this operation is incorrect and may seriously damage the router or
endanger the operator. Please follow the correct operation procedures for sake of
safety.
It indicates that during the installation and usage of the router, the operation
needs attention. This operation is incorrect and perhaps will affect the normal
operation of the router.
Please follow these safety recommendations during the installation and use of the
router:
Keep the router away from any wet place or a heat source.
Make sure that the router is normally grounded.
Please wear an ESD-preventive wrist strap before installation; make sure one
end securely contacts your skin, and the other end is well grounded.
Do not hot swap any cable.
Correctly connect the interface cable for the router. Do not connect the
telephone cable (including the ISDN cable) to the AUX port or the console
port.
Always use Uninterrupted Power Supply (UPS).

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.
