Safety Precautions
For your protection, observe the following safety precautions when setting up
and using your equipment. Failure to observe these precautions can result in
serious personal injury and damage to your equipment.
zMake sure the voltages and frequency of the power outlet matches the
electrical rating labels on the AC Adapter.
zDo not place any object on top of the device or force it into a confined
space.
zNever push objects of any kind through openings in the casing.
Dangerous voltages may be present. Conductive foreign objects could

2.2 Rear Panel and Hardware Connection
This chapter describes the proper steps for connecting your cable modem.
Please be sure to follow the steps in the sequence outlined below. Failure to
do so could result in improper operation or failure of your cable modem.
Step 1:
Connect a cable by feeding the F-connector on the back of the cable modem.
Ensure the center conductor of the 75 ohm coaxial cable is inserted directly
into the center of the F-connector. Secure the coaxial cable by carefully
threading the outer shell of the coaxial cable connector onto the F-connector
in a clockwise direction until tight. Be careful not to over-tighten the connector
or you may damage either the connector or the cable modem.
Step2: Connect the cable modem to an IEEE 802.3 10BaseT / 802.3u
100Base-TX Network using a RJ-45 male-terminated Ethernet cable or an
USB cable to the PC. This cable modem equips with two Ethernet ports, you
can connect two PCs to the cable modem at the same time if necessary.
Step 3: Connect the telephone sets to TEL1 and TEL2. Use RJ-11 telephone
line to connect TEL1/TEL2 port on the cable modem and telephone socket on
telephone.
Step 1 Connecting
the Coaxial Cable
Step 3 Connecting the
Telephone cord
Step 5 Adjust the Antenna
Step 4 Connecting to
the AC Adapter
Step 2 Connecting to a Network Interface Card
Or Connecting to the USB port on your PC

Step 4: Connect the AC Adapter to the cable modem by inserting the barrel-
shaped connector into the mating power connector on the back of the cable
modem. Exercise carefully to ensure the connectors are properly aligned prior
to insertion and ensure the two connectors engage completely. The cable
modem is shipped with an AC adapter. Remember to use only power adapter
that came with the cable modem. Other power adapters might have voltages
that are not correct for your particular cable modem. Using a power adapter
with the wrong voltage can damage the cable modem.
Step 5: Adjust the antenna if necessary.

3. Ethernet Installation
The LAN port you are using is auto-negotiating 10/100Mbps (Switch) Ethernet
Interface. You can use the Ethernet port to connect to the Internet with an
Ethernet network device such as NIC/Hub/Switch through RJ45.
Before you connect to and install the cable modem, please set the IP address
to "Obtain an IP address automatically" as below and do ensure the TCP/IP
protocol is installed on your system and configured correctly in your PC.
Following is an example of configuring the TCP/IP Protocol on Windows 98
Operating Systems:
1. Click StartÆSettingsÆControl Panel. Double click on the Network icon
click Properties.
2. A list of installed network components appears. Look for an entry named
TCP/IP. This entry may be followed by an arrow and a description of the
NIC hardware device installed in the computer. If you don't see "TCP/IP"
listed anywhere in the "The following network components are installed"
box, click the Add button, choose Protocol, and click the Add button.
Select "Microsoft" as the manufacturer and then scroll down in the list on
the right to find "TCP/IP". If you see "TCP/IP" listed, proceed to step 4.
3. Click the OK button. You will be prompted to insert the Windows 98
installation/upgrade CD.
4. Scroll down in the box until you find a line that says "TCP/IP -> " followed
by the name of your Ethernet adapter. Click on Properties and choose
"Obtain an address automatically" which means that your PC has been
configured to use DHCP (Dynamic Host Configuration Protocol).
5. Click OK.
Congratulations! You have successfully set up your cable modem.

Status
The Status page shows hardware and software information about the
CBV704EW that may be useful to your cable service provider.
5.1.1 Software Status
The Software page shows how long the CBV704EW has operated since last
being powered up, and some key information the CBV704EW received during
the initialization process with your cable service provider.
If Network Access shows “Allowed,” then your cable service provider has
configured the CBV704EW to have Internet connectivity. If Network
Access shows otherwise, you may not have Internet access, and please
contact your cable service provider for assistance.
Basic
The Basic page contains the basic features of CBV704EW including Setup,
DHCP and Backup

5.1.2 DHCP
The DHCP page allows you to activate/deactivate the DHCP server function
of the CBV704EW, and, if the DHCP server is activated, to see DHCP leases
it has provided.
With this function activated, your cable service provider’s DHCP server
provides one IP address for the CBV704EW, and the CBV704EW’s DHCP
server provides IP addresses, starting at the address you set in Starting
Local Address field, to your PCs. A DHCP server leases an IP address with
an expiration time.
To set the maximum number of PCs to which the CBV704EW will issue IP
addresses, enter it in the Number of CPEs box and then click Apply. (CPE is
another term sometimes used for PC.)
The table on the bottom of this page shows the information of DHCP clients
including the IP and MAC addresses of each PC. Since MAC addresses are
unique and permanently fixed into hardware, you can identify any PC listed by
its MAC address. The CBV704EW provides leases for 3600 seconds (default),
and has an automatic renewal mechanism that will keep extending a lease as
long as the associated PC remains active.
You can cancel an IP address lease by selecting it in the DHCP Client Lease
Info list and then clicking the Force Available button. If you do this, you may
have to perform a DHCP Renew on that PC, so it can obtain a new lease.
Advanced
The Advanced page allows you to enable/disable some advanced features of
the CBV704EW.

5.1.3 Options
The Options page allows you to enable/disable some advanced features
supported by CBV704EW.
Check the option you want to use and click Apply button to enable the
function(s).
zWAN Blocking: To prevent others on the WAN side from being able to
ping your CBV704EW. With WAN Blocking on, your CBV704EW will not
respond to pings it receives, effectively “hiding” your gateway.
zIpsec PassThrough: To enable IpSec type packets to pass through
between WAN and LAN.
zPPTP PassThrough: To enable PPTP type packets to pass through
between WAN and LAN.
zRemote Config Management: To make the Web Management pages of
your CBV704EW accessible from the WAN side. Page access is limited
to only those who know the CBV704EW access password you set in the
Status--Security page.
When accessing the CBV704EW from a remote location, you must use
HTTP port 8080 and your IP address. This is the "WAN IP address" that
appears at the Basic--Setup page. For example, if this IP address were
211.20.15.28, you would navigate to http:// 211.20.15.28:8080 to reach
the CBV704EW’s Web Management page from a remote location.
zMulticast Enable: To enable multicast traffic to pass through between
WAN and LAN. You may need to enable this to see some types of
broadcast streaming and content on the Internet, such as webcasting of a
popular live event.
zUPnP Enable: UPnP (Universal Plug and Play) offers pervasive peer-to-
peer network connectivity of PCs of all form factors, intelligent appliances,
and wireless devices. UPnP architecture leverages TCP/IP and the Web
to enable seamless proximity networking in addition to control and data
transfer among networked devices in the home, office, and everywhere in
between.
5.1.4 IP Filtering
The IP Filtering page enables you to enter the IP address ranges of PCs on
your LAN that you don’t permit to have outbound access ability to the WAN.
