Hardware Installation
In this chapter you will learn about the various connections you will need to make in order to use the Modem.
When selecting the location for the Modem, allow ample room to access the connections on the rear panel. For
convenience, try to place the Modem near your computer so you can monitor the LED indicators. Allow some
space above the Modem for ventilation to avoid problems with overheating.
Connect ADSL Line
Use the twisted-pair ADSL cable (standard telephone cable) included with the Modem to connect it to your
telephone line. Simply plug one end of the cable into the ADSL port (RJ-11 receptacle) on the rear panel of the
Modem and insert the other end into the wall jack.
Connecting One Computer to the Modem
You can connect the Modem directly to a 10/100BASE-TX Ethernet adapter card (NIC) installed on a PC using
the Ethernet cable provided as shown in this diagram.
Connecting a Local Ethernet Network to the Modem
The Modem may be connected to any 10/100BASE-TX Ethernet LAN. 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
Modem 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 Modem 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 Modem directly to a PC or server use a normal straight-through cable. You should use a crossed
cable when connecting the Modem 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. A valid connection will be indicated by
the Ethernet Link LED indicator.
The rules governing Ethernet cable lengths apply to the LAN to Modem connection. Be sure that the cable
connecting the LAN to the Modem does not exceed 100 meters.
Power On Modem
To power on the device:
1. Insert the AC Power Adapter cord into the power receptacle located on the right side panel of the Modem
and plug the adapter into a nearby power source.
2. You should see the Power LED indicator light up and remain lit.
