Section 1:Overview Congratulations on purchasing the Motorola Ethernet Broadband Router BR700. With this router you have entered the world of convenience and independence. Your router enables you to set up your own private network for your PCs to: access the Internet, share a printer, even participate in online gaming.
SECTION 1 OVERVIEW 4-port Full Duplex 10/100 Ethernet Switch and Router Enables connection of up to 4 PCs. The routing function enables each of your networked PCs to share files and printers as well. Firewall and NAT Protection Protection against Internet intruders is crucial and the built-in Firewall will protect you. Of course, the product also supports Virtual Private Network (VPN) connections through the firewall, allowing you the freedom to connect when you need it.
OVERVIEW SECTION 1 Understanding Your User Guide The User Guide is subdivided into the following sections: Overview Provides a general introduction for using your product, the type of technology used, and recommended practices for using it. Installation It is assumed that you will use the Installation Wizard on the CD-ROM to setup your unit. If not, this section provides details on getting your unit up and running. Once you have completed this section, your unit will be active and ready to work.
SECTION 1 OVERVIEW Understanding Functions The various technologies and features utilized by your router require some explanation so you can make the correct choices when configuring your router. Router Routers connect two networks together, or in your case, your home network with the Internet (which can be thought of as a very large network). Routers provide bandwidth security by keeping data out of your home network where it does not belong.
OVERVIEW SECTION 1 DHCP Server A Dynamic Host Configuration Protocol (DHCP) Server assigns IP addresses to clients connected to the router. Client is the general term used to describe any device that connects with your unit. The client (PC, gaming device, etc.) is automatically assigned an IP address every time a device is added to your network, freeing you from manually assigning IP addresses.
SECTION 1 OVERVIEW Router Physical Description The following sections describe the physical characteristics of your unit. Back of Router The following illustration shows the BR700 back panel: 1 2 3 4 5 6 7 4 3 2 1 WAN Reset Power LAN Feature Description 1 Power The receptacle where you plug in the power adapter. 2 Reset Button A dual-function button. It either resets your unit or resets the unit to the default login settings.
OVERVIEW SECTION 1 3-6 Feature Description LAN Ports 1-4 These four ports can connect your LAN with Ethernet cables. This enables communication among clients, such as PCs or print servers, on the network. The LAN ports support either 10-BASE-T or 100-BASE-T transmission speeds as well as straight-through and crossover Ethernet cables. Any of these four ports can also serve as an uplink port to other network devices, enabling you to extend your network.
