This chapter provides basic instructions for connecting the device to a computer or LAN and
to the Internet.
In addition to configuring the device, you need to configure the Internet properties of your
computer(s). For more details, see the following sections in Appendix A:
This chapter assumes that you have already established a DSL 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.
Connecting the Hardware
This section describes how to connect the device to the power outlet and your computer(s)
or network.
Before you begin, turn the power off for all devices. These include
your computer(s), your LAN hub/switch (if applicable), and the device.
WARNING
The diagram below illustrates the hardware connections. The layout of the ports on your
device may vary from the layout shown. Refer to the steps that follow for specific
instructions.
Figure 8: Overview of Hardware Connections for X7967r
9
X7968r / X7967r / X7927r / X7922r User’s Guide
Step 1. Connect the DSL cable and optional telephone line
Connect one end of the provided phone cable to the port labeled DSL on the rear panel of the
device. Connect the other end to ADSL spliter.
Step 2. Connect the Ethernet cable
Connect up to four single Ethernet computers or to a HUB/Switch directly to the device via
Ethernet cable(s).
Note that the cables do not need to be crossover cables.
Step 3. Attach the power connector
Connect the AC power adapter to the Power connector on the back of the device and plug
the adapter into a wall outlet or power strip. Turn on and boot up your computer(s) and any
LAN devices such as hubs or switches.
Step 4. Configure your Ethernet PCs
You must also configure the Internet properties on your Ethernet PCs. See Configuring
Ethernet PCs section.
Step 5. Install a Wireless card and connect Wireless PCs
You can attach a Wireless LAN that enables Wireless PCs to access the Internet via the
device.
You must configure your Wireless computer(s) in order to access your device. For complete
instructions, see Configuring Wireless PCs section.
Step 6. Install an USB driver (for X7967r and X7927r only)
You can attach a single computer to the device using a USB cable. The USB port is useful if
you have an USB-enabled PC that does not have a network interface card for attaching to
your Ethernet network.
Before attaching the USB cable, you must install an USB driver on your PC and configure the
computer. For complete instructions, see Configuring an USB PC section.
Next step
After setting up and configuring the device and PCs, you can log on to the device by
following the instructions in “Getting Started with the Web pages” on chapter 4. The chapter
includes a section called Testing your Setup, which enables you to verify that the device is
working properly.
