3 Quick Start Guide 
This Quick Start Guide provides basic instructions for connecting the RX3141 to a computer or a network and 
to the Internet. 
f  Part 1 provides instructions to set up the hardware. 
f  Part 2 describes how to configure Internet properties on your computer(s). 
f  Part 3 shows you how to configure basic settings on the RX3141 to get your LAN connected to the 
Internet. 
After setting up and configuring the device, you can follow the instructions on page 17 to verify that it is working 
properly. 
This Quick Start Guide assumes that you have already established ADSL or cable modem service with your 
Internet service provider (ISP). These instructions provide a basic configuration that should be compatible with 
your home or small office network setup. Refer to the subsequent chapters for additional configuration 
instructions. 
3.1  Part 1 — Connecting the Hardware 
In Part 1, you connect the device to an ADSL or a cable modem (which in turn is connected to a phone jack or 
a cable outlet), the power outlet, and your computer or network. 
 
WARNING 
Before you begin, turn the power off for all devices. These 
include your computer(s), your LAN hub/switch (if applicable), 
and the RX3141. 
 
Figure 3.1 illustrates the hardware connections. Please follow the steps that follow for specific instructions. 
3.1.1  Step 1. Connect an ADSL or a cable modem. 
For the RX3141: Connect one end of the Ethernet cable to the port labeled WAN on the rear panel of the 
device. Connect the other end to the Ethernet port on the ADSL or cable modem. 
3.1.2  Step 2. Connect computers or a Network. 
If your LAN has no more than 4 computers, you can use an Ethernet cable  to connect computers directly to 
the built-in switch on the device. Note that you should attach one end of the Ethernet cable to any of the port 
labeled 1 – 4 on the rear panel of the router and connect the other end to the Ethernet port of a computer. 
If your LAN has more than 4 computers, you can attach one end of an Ethernet cable to a hub or a switch 
(probably an uplink port; please refer to the hub or switch documentations for instructions) and the other to the 
Ethernet switch port (labeled 1 – 4) on the RX3141. 
Note that either the crossover or straight-through Ethernet cable can be used to connect the built-in switch and 
computers, hubs or switches as the built-in switch is smart enough to make connections with either type of 
cables.

3.2.6  Assigning static IP addresses to your PCs 
In some cases, you may want to assign IP addresses to some or all of your PCs directly (often called 
“statically”), rather than allowing the RX3141 to assign them. This option may be desirable (but not required) if: 
f  You have obtained one or more public IP addresses that you want to always associate with specific 
computers (for example, if you are using a computer as a public web server). 
f  You maintain different subnets on your LAN. 
However, during the first time configuration of your RX3141, you must assign an IP address in the 192.168.1.0 
network for your PC, say 192.168.1.2, in order to establish connection between the RX3141 and your PC as 
the default LAN IP on RX3141 is pre-configured as 192.168.1.1. Enter 255.255.255.0 for the subnet mask and 
192.168.1.1 for the default gateway. These settings may be changed later to reflect your true network 
environment. 
On each PC to which you want to assign static information, follow the instructions on pages 13 through 15 
relating only to checking for and/or installing the IP protocol. Once it is installed, continue to follow the 
instructions for displaying each of the Internet Protocol (TCP/IP) properties. Instead of enabling dynamic 
assignment of the IP addresses for the computer, DNS server, and default gateway, click the radio buttons that 
enable you to enter the information manually. 
 
Note 
Your PCs must have IP addresses that place them in the same subnet as the RX3141’s 
LAN port. If you manually assign IP information to all your LAN PCs, you can follow the 
instructions in the section 5.1.1 to change the LAN port IP address accordingly.
