Hardware Overview

LEDs

Power

A steady green light indicates the unit is powered on.

When the device is powered off this remains dark. Lights

steady green during power on self-test (POST). Once the

connection status has been settled, the light will blink

green. If the indicator lights steady green after the POST,

the system has failed and the device should be rebooted.

Internet

A solid green light indicates the WAN IP address from IPCP or

DHCP and DSL is up or a static IP address is configured and

PPP negotiation has been successfully completed. If the

indicator blinks green, this means the Router is active. If the

Router power is off, this remains dark. A solid red light indicates

there is no DHCP response, no PPPoE response, PPPoE

authentication has failed, and/or there is no IP.

DSL

A steady green light indicates a valid

ADSL connection. This will light after

the ADSL negotiation process has

been settled. A blinking green light

indicates activity on the WAN

(ADSL) interface.

LAN

A solid green light indicates a valid link on

startup. This light will blink when there is activity

currently passing through the Ethernet port.

Installation

This section will walk you through the installation process. Placement of the Router is very important. Do not place the Router in an enclosed area

such as a closet, cabinet, or in the attic or garage.

Before You Begin

Please read and make sure you understand all the prerequisites for proper installation of your new Router. Have all the necessary information and

equipment on hand before beginning the installation.

Installation Notes

In order to establish a connection to the Internet it will be necessary to provide information to the Router that will be stored in its memory. For some

users, only their account information (Username and Password) is required. For others, various parameters that control and define the Internet

connection will be required. You can print out the two pages below and use the tables to list this information. This way you have a hard copy of all

the information needed to setup the Router. If it is necessary to reconfigure the device, all the necessary information can be easily accessed. Be

sure to keep this information safe and private.

Low Pass Filters

Since ADSL and telephone services share the same copper wiring to carry their respective signals, a filtering mechanism may be necessary to

avoid mutual interference. A low pass filter device can be installed for each telephone that shares the line with the ADSL line. These filters are easy

to install passive devices that connect to the ADSL device and/or telephone using standard telephone cable. Ask your service provider for more

information about the use of low pass filters with your installation.

Operating Systems

The DSL-2542B uses an HTML-based web interface for setup and management. The Web configuration manager may be accessed using any

operating system capable of running web browser software, including Windows 98 SE, Windows ME, Windows 2000, Windows XP, and Windows

Vista.

Web Browser

Any common Web browser can be used to configure the Router using the Web configuration management software. The program is designed to

work best with more recently released browsers such as Opera, Microsoft Internet Explorer® version 6.0, Netscape Navigator® version 6.2.3, or

later versions. The Web browser must have JavaScript enabled. JavaScript is enabled by default on many browsers. Make sure JavaScript has not

been disabled by other software (such as virus protection or web user security packages) that may be running on your computer.

Ethernet Port (NIC Adapter)

Any computer that uses the Router must be able to connect to it through the Ethernet port on the Router. This connection is an Ethernet connection

and therefore requires that your computer be equipped with an Ethernet port as well. Most notebook computers are now sold with an Ethernet port

already installed. Likewise, most fully assembled desktop computers come with an Ethernet NIC adapter as standard equipment. If your computer

does not have an Ethernet port, you must install an Ethernet NIC adapter before you can use the Router. If you must install an adapter, follow the

installation instructions that come with the Ethernet NIC adapter.

Additional Software

It may be necessary to install software on your computer that enables the computer to access the Internet. Additional software must be installed if

you are using the device a simple bridge. For a bridged connection, the information needed to make and maintain the Internet connection is stored

on another computer or gateway device, not in the Router itself.

If your ADSL service is delivered through a PPPoE or PPPoA connection, the information needed to establish and maintain the Internet connection

can be stored in the Router. In this case, it is not necessary to install software on your computer. It may however be necessary to change some

settings in the device, including account information used to identify and verify the connection.

All connections to the Internet require a unique global IP address. For bridged connections, the global IP settings must reside in a TCP/IP enabled

device on the LAN side of the bridge, such as a PC, a server, a gateway device such as a router or similar firewall hardware. The IP address can be

assigned in a number of ways. Your network service provider will give you instructions about any additional connection software or NIC

configuration that may be required.

Information you will need from your ADSL service

provider

Username

This is the Username used to log on to your ADSL service provider’s network. Your ADSL service provider uses this to identify your account.

Password

This is the Password used, in conjunction with the Username above, to log on to your ADSL service provider’s network. This is used to verify the

identity of your account.

WAN Setting / Connection Type

These settings describe the method your ADSL service provider uses to transport data between the Internet and your computer. Most users will use

the default settings. You may need to specify one of the following WAN Setting and Connection Type configurations (Connection Type settings listed

in parenthesis):

•

PPPoE/PPoA (PPPoE LLC, PPPoE VC-Mux, PPPoA LLC, or PPPoA VC-Mux)

•

Dynamic IP Address (1483 Bridged IP LLC or 1483 Bridged IP VC-Mux)

•

Static IP Address (Bridged IP LLC, 1483 Bridged IP VC Mux, 1483 Routed IP LLC, 1483 Routed IP VC-Mux)

•

Bridge Mode (1483 Bridged IP LLC or 1483 Bridged IP VC Mux)

Modulation Type

ADSL uses various standardized modulation techniques to transmit data over the allotted signal frequencies. Some users may need to change the

type of modulation used for their service. The default DSL modulation (Autosense) used for the Router automatically detects all types of ADSL,

ADSL2, and ADSL2+ modulation.

Security Protocol

This is the method your ADSL service provider will use to verify your Username and Password when you log on to their network. Your Router

supports the PAP and CHAP protocols.

VPI

Most users will not be required to change this setting. The Virtual Path Identifier (VPI) is used in conjunction with the Virtual Channel Identifier (VCI)

to identify the data path between your ADSL service provider’s network and your computer. If you are setting up the Router for multiple virtual

connections, you will need to configure the VPI and VCI as instructed by your ADSL service provider for the additional connections. This setting can

be changed in the WAN Settings window of the web management interface.

VCI

Most users will not be required to change this setting. The Virtual Channel Identifier (VCI) used in conjunction with the VPI to identify the data path

between your ADSL service provider’s network and your computer. If you are setting up the Router for multiple virtual connections, you will need to

configure the VPI and VCI as instructed by your ADSL service provider for the additional connections. This setting can be changed in the WAN

Settings window of the web management interface.

Information you will need about DSL-2542B
