type of modulation used for their service. The default DSL modulation (ADSL2+ Multi-Mode) used for the Router automatically detects all types of

ADSL, ADSL2, and ADSL2+ modulation.

Security Protocol

Information you will need about your LAN or computer

:

Ethernet NIC

If your computer has an Ethernet NIC, you can connect the DSL-2540U to this Ethernet port using an Ethernet cable. You can also use the Ethernet

ports on the DSL-2540U to connect to other computer or Ethernet devices.

DHCP Client status

Your DSL-2540U ADSL Router is configured, by default, to be a DHCP server. This means that it can assign an IP address, subnet mask, and a

default gateway address to computers on your LAN. The default range of IP addresses the DSL-2540U will assign are from 192.168.1.2 to

192.168.1.254. Your computer (or computers) needs to be configured to obtain an IP address automatically (that is, they need to be configured as

DHCP clients.)

It is recommended that your collect and record this information here, or in some other secure place, in case you have to re-configure your ADSL

connection in the future.

Once you have the above information, you are ready to setup and configure your DSL-2540U ADSL Router.

Device Installation

The DSL-2540U connects two separate physical interfaces, an ADSL (WAN) and an Ethernet (LAN) interface. Place the Router in a location where

it can be connected to the various devices as well as to a power source. The Router should not be located where it will be exposed to moisture or

excessive heat. Make sure the cables and power cord are placed safely out of the way so they do not create a tripping hazard. As with any electrical

appliance, observe common sense safety procedures.

The Router can be placed on a shelf or desktop, ideally you should be able to see the LED indicators on the front if you need to view them for

troubleshooting.

Power on Router

The Router must be used with the power adapter included with the device.

1. Insert the DC Power Adapter cord into the power receptacle located on the rear panel of the Router and plug the adapter into a suitable nearby

power source.

2.

Depress the Power button into the on position. You should see the Power LED indicator light up and remain lit. The Status LED should light solid

green and begin to blink after a few seconds.

3. If the Ethernet port is connected to a working device, check the Ethernet Link/Act LED indicators to make sure the connection is valid. The

Router will attempt to establish the ADSL connection, if the ADSL line is connected and the Router is properly configured this should light up

after several seconds. If this is the first time installing the device, some settings may need to be changed before the Router can establish a

connection.
