DSL-2740B Wireless ADSL Router User Guide

Network Connections
Wired network connections are provided through the ADSL port and the four Ethernet ports on the back of the Router.
See the Rear Panel diagram above and the illustrations below for examples
Connect ADSL Line
Use the ADSL cable included with the Router to connect it to a telephone wall socket or receptacle. Plug one end of the
cable into the ADSL port (RJ-11 receptacle) on the rear panel of the Router and insert the other end into the RJ-11 wall
socket. If you are using a low pass filter device, follow the instructions included with the device or given to you by your
service provider. The ADSL connection represents the WAN interface, the connection to the Internet. It is the physical
link to the service provider’s network backbone and ultimately to the Internet.
Connect Router to Ethernet
The Router may be connected to a single computer or Ethernet device through the 10BASE-TX Ethernet port on the
rear panel. Any connection to an Ethernet concentrating device such as a switch or hub must operate at a speed of
10/100 Mbps only. When connecting the Router to any Ethernet device that is capable of operating at speeds higher
than 10Mbps, be sure that the device has auto-negotiation (NWay) enabled for the connecting port.
Use standard twisted-pair cable with RJ-45 connectors. The RJ-45 port on the Router is a crossed port (MDI-X). Follow
standard Ethernet guidelines when deciding what type of cable to use to make this connection. When connecting the
Router directly to a PC or server use a normal straight-through cable. You should use a crossed cable when connecting
the Router to a normal (MDI-X) port on a switch or hub. Use a normal straight-through cable when connecting it to an
uplink (MDI-II) port on a hub or switch.
The rules governing Ethernet cable lengths apply to the LAN to Router connection. Be sure that the cable connecting
the LAN to the Router does not exceed 100 meters.
Hub or Switch to Router Connection
Connect the Router to an uplink port (MDI-II) on an Ethernet hub or switch with a straight-through cable as shown in
the diagram below:
If you wish to reserve the uplink
port on the switch or hub for
another device, connect to any on
the other MDI-X ports (1x, 2x, etc.)
with a crossed cable.
