1. PRODUCT DESCRIPTION
Your Westell® Router provides reliable, high-speed, Internet access to your existing small office phone line. Your
ADSL connection is “always-on” ending the hassles of dial-up modems and busy signals. Installation is easy ... no
tools ... no headaches. Simply connect the hardware, apply power, and perform the simple software configuration for
Router and you are on the Internet.
The Westell® Router is capable of data rates hundreds of times faster than a traditional analog modem. But unlike
analog modems, your Westell® Router allows you to use the same phone line for simultaneous voice/fax
communications and high-speed Internet access, eliminating the need for dedicated phone lines for voice and data
needs. The Router supports a variety of networking interfaces such as wireless 802.11b/g/g+, ADSL, Ethernet and
the following optional features:
NOTE: The actual features and functions of your product may vary depending on the model you are using.
2. SAFETY INSTRUCTIONS
Never install any telephone wiring during a lightning storm.
Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
Never touch non-insulated telephone wires or terminals unless the telephone line has been disconnected at the
network interface.
Use caution when installing or modifying telephone lines.
WARNING
Risk of electric shock. Voltages up to 140 Vdc (with reference to
ground) may be present on telecommunications circuits.

3. REGULATORY INFORMATION
3.1 FCC Compliance Note
(FCC ID: CH8-328WXX-6)
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15
of the Federal Communication Commission (FCC) Rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This equipment generates, uses, and can radiate radio
frequency energy, and if not installed and used in accordance with the instructions, may cause harmful interference
to radio communications. However, there is no guarantee that interference will not occur in a particular installation.
If this equipment does cause harmful interference to radio or television reception, which can be determined by
turning the equipment OFF and ON, the user is encouraged to try to correct the interference by one or more of the
following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and the receiver.
• Connect the equipment to a different circuit from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
Modifications made to the product, unless expressly approved by Westell Inc., could void the users’ right to
operate the equipment.
RF EXPOSURE
This device has been tested and complies with FCC RF Exposure (SAR) limits in typical laptop computer
configurations and this device can be used in desktop or laptop computers with side-mounted PCMCIA slots,
which can provide 1 cm separation distance from the antenna to the body of the user or a nearby person.
Thin laptop computers may need special attention to maintain antenna spacing while operating. This device
cannot be used with handheld PDAs (personal digital assistants). Use in other configurations may not ensure
compliance with FCC RF exposure guidelines. This device and its antenna must not be co-located or operate
in conjunction with another antenna or transmitter.
PART 68 – COMPLIANCE REGISTRATION
This equipment (Models 7400, 7401, 328W10, 328W11) complies with Part 68 of the FCC rules and the
requirements adopted by the ACTA. A label on the bottom of this equipment contains, among other information, the
Ringer Equivalence Number (REN) and the product identifier. For products approved after July 23, 2001 the
product identifier is in the format US:AAAEQ##TXXXX. The digits represented by ## are the REN without a
decimal point (e.g. 03 is a REN of 0.3). The REN is used to determine the number of devices that may be connected
to a telephone line. For earlier products, the REN is separately shown on the label. If requested, this number must be
provided to the telephone company.
Excessive RENs on a telephone line may result in the devices not ringing in response to an incoming call. In most,
but not all areas, the sum of RENs should not exceed five (5.0). To be certain of the number of devices that may be
connected to a line, as determined by the total RENs, contact the local telephone company.
This equipment is designated to connect to the telephone network or premises wiring using a compatible modular
jack that is Part 68 compliant. An FCC compliant telephone cord and modular plug is provided with the equipment.
See the Installation Information section of this User Guide for details.

6. INSTALLING THE HARDWARE
6.1 Installation Requirements
To install your Router, you will need the following:
• A Network Interface Card (NIC) installed in your PC
• An IEEE 802.11b/g adapter (Models 328W10, 328W11 only)
NOTE: Internet service provider subscriber software and connection requirements may vary. Consult your ISP for
installation instructions. Please wait until you have received notification from your ISP that your DSL line has been
activated before installing the Router and the software.
6.2 Before you begin
Make sure your kit contains the following items:
• Westell® Router
• Power Supply
• RJ-45 Ethernet cable (straight-through) (yellow)
• USB Cable (blue) (Models 7400, 328W10 only)
• RJ-11 Phone cable
• SMA Antenna (Models 328W10, 328W11 only)
• Westell CD-ROM containing User Guide in PDF format
• Quick Start Guide
6.3 Microfilters
ADSL signals must be blocked from reaching each telephone, answering machine, fax machine, computer modem
or any similar conventional device. Failure to do so may degrade telephone voice quality and ADSL performance.
Install a microfilter if you desire to use the DSL-equipped line jack for telephone, answering machine, fax machine
or other telephone device connections. Microfilter installation requires no tools or telephone rewiring. Just unplug
the telephone device from the baseboard or wall mount and snap in a microfilter, next snap in the telephone device.
You can purchase microfilters from your local electronics retailer, or contact the original provider of your DSL
equipment.

6.4 Hardware Installations
NOTE: If you are using the Router in conjunction with an Ethernet Hub or Switch, refer to the manufacturer’s
instructions for proper installation and configuration. When using a Microfilter, be certain that the DSL phone cable
is connected to the “DSL/HPN” non-filtered jack. Please wait until you have received notification from your ISP
that your DSL line has been activated before installing the Router. Westell recommends the use of a surge
suppressor to protect equipment attached to the power supply.
6.4.1 Installation via 10/100 Base-T Ethernet
IMPORTANT: Before you connect via 10/100 Base-T, you must have an available Ethernet card installed
in your computer. If your Ethernet card does not auto-negotiate, you must set it to half duplex. Refer to the
Ethernet card manufacturer’s instructions for installing and configuring your Ethernet card.
Warning: Your power requirements may differ from those displayed in the following instructions. You must use
only the power adapter provided with your kit.
1. Connect the power supply cord to the power connector marked 15 VAC on the rear panel of the Router. Plug
the other end of the power supply into a wall socket.
2. Connect the DSL phone cable from the connector marked DSL on the rear panel of the Router to the DSL-
equipped telephone line jack on the wall. IMPORTANT: Do not use a DSL filter on this connection. You must
use the phone cord that was provided with the kit.
3. Connect the yellow Ethernet cable from any one of the Ethernet jacks marked
on the rear panel of the
Router to the Ethernet port on your computer. Repeat this step to connect up to three additional PCs to your
Westell Router.
NOTE: You may connect to any of the four Ethernet jacks on the rear panel as they serve as an Ethernet switch.
However, when using the optional UPLINK/E1 port, Ethernet LAN connection is limited to ports E2, E3, and E4.
4. Check to see if the DSL LED is solid green. If the DSL LED is solid green, the Router is functioning properly.
5. Check to see if the Ethernet LED is solid green. Solid green indicates that the Ethernet connection is
functioning properly.
Congratulations! You have completed the Ethernet hardware installation. No software installation is required when using
only an Ethernet connection. You must now proceed to section 8 to configure your Router for Internet connection.

6.4.2 Connecting PCs via Wireless (Models 328W10, 328W11)
IMPORTANT: If you are connecting to the Router via a wireless network adapter, the SSID must be the same for
both the Router and your PC’s wireless network adapter. The default SSID for the Router is the serial number of the
unit (located below the bar code on the bottom of the unit and also on the Westell shipping carton). Locate and run
the utility software provided with your PC’s Wireless network adapter and enter the SSID value. The PC’s wireless
network adapter must be configured with the SSID (in order to communicate with the Router) before you begin the
account setup and configuration procedures. Later, for privacy you can change the SSID by following the
procedures outlined in section 13.4 (Wireless Configuration).
IMPORTANT: Client PCs can use any Wireless Fidelity (Wi-Fi) 802.11b/g/g+ certified card to communicate with
the Router. The Wireless card and Router must use the same security code type. If you use WPA-PSK or WEP
wireless security, you must configure your computer’s wireless adapter for the security code that you use.
You can access the settings in the advanced properties of the wireless network adapter.
