REBOOTING THE MODEM WITH THE R ESET BUTTON
The reset button on the back panel of your modem is provided to reboot the modem without the need to remove
power .
Under normal circumstances, you will not have to use the reset button. On rare occasions, however, your modem
may not respond. In this case, you need to perform a reset to get your modem running properly again (see
“Rebooting the Modem” on page 5-14 for information about rebooting the modem from the Web Interface, and
“Rebooting the Modem” on page A-29 for information about rebooting the modem from the Command Line
Interface).
To perform a reboot:
Step Action
1 Use the tip of an unfolded paper clip (or similar object without a sharp tip) to gently press the Reset bu tton
on the back panel of your modem for less than 5 seconds (see Figure 1-4). The modem then reboots.
IMPORTANT
!
Holding down on the Reset button for MORE than 5 seconds resets the modem to its
factory default settings, essentially clearing all of your current configuration settings.
For detailed information about resetting the modem’ s factory defaults:
• Using the Web Interface , see “Reset to Factory Defaults using the Web Interface ” on

ACCESSING THE WEB INTERFACE FOR MODEM MANAGEMENT
Use the Web interface as the most comprehensive and convenient way to set up and manage the modem. This
chapter provides steps to help you access the Web interface pages for configuration and management of the
modem.
Access to the command line interface is available through the modem console port or over a network using a telnet
session. Not all configuration and management features, however, are supported through the command line
interface. See Appendix A: “Command Line Interface Access” on page A-1 for instruction on using the command
line interface for configuration and management.
ASSIGN IP ADDRESSES
To access the modem Web interface, the management PC must be on the same LAN
IP subnet as the modem. Default values are shown to the right. Do one of the following:
• Change the management PC IP address so that it is on the same subnet as the
modem (go to Step 1 below).
• Change the IP address of the modem 10/100Base-T (LAN) port to a value
assigned by your network administrator using the command line interface (go to
Appendix A: “Set Up the LAN” on page A-6).
Use the following steps to set up a management PC to be on the same subnet with the modem. (The example
shows instructions for a PC that is running Microsoft Windows 98 SE; instructions for other operating systems may
differ slightly.)
Step Action
1 From the Windows desktop, choose Start | Settings | Control Panel to open the Control Panel dialog.
2 From the Control Panel dialog, double-click the Network icon (shown to the right).
The Network dialog is displayed.
3 From the Configuration tab, double-click TCP/IP to display the TCP/IP Properties dialog (Figure 2-1).

CONFIGURING THE LAN
The LAN configuration sets up the interface between the mo dem 10/100Base-T LAN port and devices on the LAN.
The LAN is managed by your network administrator, who will make the decisions concerning its topology.
For instructions on setting up the LAN interface for a point-to-point modem application, go to Chapter 7:
Implementing a Point-To-Point LAN Extension.
BEFORE YOU BEGIN
Your network administrator will:
• Determine if you will use the modem Ethernet port in auto, full- or half-duplex mode.
• Identify a subnet value, including IP addresses and subnet masks.
• Determine if DHCP for the modem is enabled. If it is enabled, determine if the modem will be configured as a:
– DHCP client which receives an IP address from another device that is a DHCP server on the LAN
– DHCP server (determine the range of IP addresses the modem will need to serve, and identify the DHCP
gateway and DNS server)
– DHCP relay agent (determine the IP address to which the DHCP functions will be relayed)
• Determine if DNS Relay mode for the modem is enabled. If it is, identify the IP address for the DNS server.
CONFIGURE THE LAN
From the LAN Configuration page, configure the parameters for the LAN as indicated by your system administrator.
The default protocol for the LAN port is bridged.
Step Action
1 Select LAN on the menu bar, then select LAN Setup under LAN Options to access the LAN
Configuration page (see Figure 3-1).
Figure 3-1. LAN Configuration
MM70xG2-UM-03 3-1
Chapter 3: Provisioning April 14, 2006
Step Action
2 Configure the following parameters:
• LAN Protocol
The LAN protocol is set to Bridged and cannot be changed through the Web interface. If you want to
change the protocol to Routing, use the command line interface (go to “Set Up the LAN” on page A-6).
• IP Address
See the LAN administrator for a LAN IP address. Do one of the following:
– Enter an IP address for the LAN (10/100Base-T) port provided by the LAN administrator
– Use the default IP address for the LAN port, which is 10.0.0.1. If you choose to use the default IP
address, make sure the devices on your LAN are on the same subnet as this modem LAN port.
– If you want a DHCP server on your LAN to automatically provide the modem LAN port IP address,
select Client for the DHCP configuration (see DHCP Client below).
• Subnet Mask
See the LAN administrator for the subnet mask. Do one of the following:
– Enter the subnet mask for the LAN (10/100Base-T) port provided by the LAN administrator.
– Use the default subnet mask for the LAN port, which is 255.255.255.0. If you choose to use the
default subnet mask, make sure it allows devices on your LAN to access the modem LAN port.
– If you want a DHCP server on your LAN to automatically provide the subnet mask in addition to the
IP address, select Client for the DHCP configuration (see DHCP Client below).
•DHCP Client
Note: If a DHCP server is not set up and active on your LAN, do not enable DHCP client.
DHCP Client mode is recommended for use only when bridging is used as the LAN
protocol.
A DHCP server must be set up and active on the LAN prior to enabling this feature. When DHCP
Client is Enabled, the modem automatically changes the LAN port IP address to all zero es so that the
DHCP server on the LAN can immediately serve it an IP address. This parameter is used when the
LAN port is in bridging mode only.
CONFIGURE DNS RELAY MODE
The DNS resolver on a DNS server maps human-readable addresses to IP address numbers. A human-readable
address is one such as:
maggie.copro.company.com
As a DNS relay, the modem forwards requests for DNS resolution to another device on the LAN or WAN that
performs the resolution service. When you enable DNS Relay mode, enter the IP address for the device that will
perform DNS resolution. Either your service provider or LAN administrator will provide this IP address.
If the modem is configured as a DHCP client (see “Configure the LAN” on page 3-1), it is served a DNS address in
addition to an IP address and subnet mask. The DNS relay will be automatically enabled and the DNS server IP
address will be automatically displayed in the DNS server IP address field, as shown in Figure 3-3 on page 3-3.
If you do not enable DNS relay nor do you ena ble DHCP client, then you must add the IP address for a DNS
resolver to the Internet Protocol (TCP/IP) se tup for your PC (or other DHCP client). See Step 2 on page 3-5 for more
information on setting up this information.

CONFIGURE DHCP SERVER MODE
From the DHCP server mode page, configure the p arameters for th e modem to function as a DHCP server by either
directly serving IP addresses (DHCP server) or forwarding the request to another device that will provide DHCP
services (DHCP relay agent). If you selected DHCP client when you configured LAN parameters (on page 3-2),
then DHCP server mode is automatically set to Disabled.
Step Action
1 Select LAN on the menu bar, then select DHCP Server under LAN Options to access the DHCP server
mode page.

Step Action
2 Select one of the following three DHCP server modes as indicated by your LAN administrator, then click
Configure:
• Disabled—DHCP server mode is not enabled. If you do not enable DHCP server for the modem, you
must enter a default gateway for each client on your LAN (such as PCs) and also an IP address for a
DNS server. Either the service provider or your LAN administrator will provide you these IP addresses
to enter in the Internet Protocol (TCP/IP) setup for your PC (or other LAN clients). See “Assign IP
Addresses” on page 2-1 for information about how to access this dialog. The following is an example
of the dialog and fields that must be filled in (example is from Windows 2000; the dialog for other operating systems may be slightly different).
Set Internet protocol to: Use
the following IP address:
DHCP default gateway
IP address
DNS server IP address
Figure 3-5. Internet Protocol (TCP/IP) Properties
• Enabled—The modem functions as a DHCP server and can serve IP addresses, a DHCP gateway,
and a DNS server IP address to devices on your LAN. When the modem DHCP server is enabled,
then LAN clients (such as PCs) must have their Internet protocol (TCP/IP) set to Obtain an IP
address automatically (see Figure 3-5 above for an example of where to select this option).
a. Select Enabled, then click Configure to access the following DHCP Server page (DHCP Server
cannot be enabled when the LAN protocol is in bridge mode).

(cont.)
b. Configure the following parameters when DHCP server is enabled for the modem:
– DHCP Range Low
The lowest IP address value that the modem can serve when configured as a DHCP Server. A
maximum of 20 IP addresses can be served by the modem. This IP address value is provided by
your LAN administrator and must be on the same subnet as the modem LAN port.
– DHCP Range High
The highest IP address value that the modem can serve when configured as a DHCP Server. A
maximum of 20 IP addresses can be served by the modem. This IP address value is provided by
your LAN administrator and must be on the same subnet as the modem LAN port.
– Default Lease Time
The default amount of time, in seconds, that a device on the LAN can be bound to the IP address it
was served before the lease expires. This value is provided by your LAN administrator.
– Max Lease Time
The maximum amount of time, in seconds, that a device on the LAN can be bound to the IP address
it was served before the lease expires. This value is provided by your LAN administrator.
– DHCP Default Gateway
Enter the IP address of the DHCP default gateway that is provided by the LAN administrator for
devices on the LAN. After you configure this IP address, the modem provides this IP address as a
default DHCP gateway to requesting DHCP clients (such as PCs) on the LAN. If there are no
gateways on the LAN, then the modem LAN port IP address can be assigned as the gateway.
– DHCP DNS Server
Enter the IP address of the Domain Name System (DNS) server that will translate human-readable
addresses to IP addresses. The DNS server can be either on the LAN or the WAN side of the
modem. The modem provides this IP address as a default DNS server to requesting DHCP clients
(such as PCs) on the LAN. If the DNS server is on the LAN side of the modem, acquire the IP
address from your LAN administrator . If the DNS server is on the WAN side of the server, acquire
the IP address from the service provider.
If you enabled DNS relay on page 3-3 and entered a DNS server IP address, then enter the modem
LAN port IP address as the DHCP DNS server.
• DHCP relay agent—The modem forwards the request for an IP address, DHCP default gateway, and
DNS server IP address to a device acting as a DHCP server. The DHCP server can be either on the
LAN or the WAN side of the modem. If on th e LAN side, acquire the IP ad dress fro m yo ur LAN admin istrator. If on the WAN side, acquire the IP addr ess fro m the service provider.
a. Select DHCP relay agent, then click Configure to access the following DHCP Server page.
Figure 3-7. DHCP Server Page
b. Enter the DHCP Server IP address for the device to which the modem will forward DHCP services
requests, then click Apply.
