2. General Overview

This document supports both the 3641-80 Single Port router and the 3648-80 router which includes an 8 port Ethernet switch. The router cards are Ethernet IP routers, which mounts in a full size card slot. The only difference between the 3641-80 and 3648-80 is that the 3648-80 has an unmanaged Ethernet switch to eliminate the need for an external switch. Therefore the routers will be referred to as ‘the router’. The router includes an Ethernet interface to provide data services from the T1/E1 interface. The router can act as a frame relay router, frame relay bridge, firewall, VPN gateway, or IP sharing.

For purposes of understanding, the Ethernet port represents the LAN side of the router and the T1/E1 represents the WAN side of the router.

The router card provides three primary services:

1. Provides a standard T1/E1 gateway function between the customer Ethernet interface and

the WAN data service channel on the T1/E1 interface.

2. Provides the possibility for including voice and data over the same T1/E1 line.

3. Provides a flexible programmable data rate 56/64K x N bps where N = 1…24 for T1, 1…30

for E1 (i.e. 56K ~ 1.536M bps for T1, 56K ~ 1.92M bps for E1).

5. Installation

5.1. Preparing Before Installation

The major functions of the Router Card are performed by the Ethernet network interface. Your computer must have an Ethernet Network Interface Card (NIC) installed and set up with the TCP/IP protocol before beginning to use the router. The router also provides a serial console port for monitoring and configuring the router via the built-in command line interface.

You will need to know the Internet Protocol supported by your T1/E1 provider to successfully connect to the Internet. For future troubleshooting or reinstallation, it is important that you retain these details.

Before beginning the hardware installation, please gather the following materials for the setup.  At least one computer running a supported *operating system, with an Ethernet Network

Interface Card (NIC) installed (or more computers if you use an external hub).

 TCP/IP protocol installed for each NIC.  Ethernet straight connect cable (one for each computer you will be connecting)  RS-232 serial cable (Optional)

* The router Web Configuration tool supports browsers that operate under Windows 95, 98, 2000, XP and Unix system. Configuration can also be done via telnet, ftp or through an RS-232 RTR MGMT port.

5.2. Installation Procedures

To install the router card, follow the procedure in the router practice (LT364-180-202) or the router installation guide (LT364-180-802).

Issue 1.0, April 2006 Section 364-180-N02

6. Web Configuration Tool

6.1. About the Web Configuration

The Web Configuration tool provides a series of web pages that you can use to setup and configure your Router card. There are three main menus. You can select each of the following menus from the left frame of the main window:

 Status Menu: Information about the current setup and status of the system and system hardware and options..

 System Menu: Information about the error log, upgrading the firmware and restarting the system.

 Configuration Menu: Information about the current configuration of various system features with options to change the configuration.

NOTE: There are certain features that are only accessible through the Web Configuration Tool:

1. Digital signature certificates of IPSec

2. Remote upgrade firmware (by browser http-upload.tar file)

3. Errorlog

6.2. Factory Default Settings

If your required configuration exactly matches the settings below, the router will work for you as pre-configured. After completing the installation, assigning your static IP address to your computer’s TCP/IP settings, you should be able to make a connection to the Internet.

LAN Port: IP Address: 192.168.0.1 Subnet Mask: 255.255.255.0

DHCP Server: Disabled Loopback: IP Address: 127.0.0.1

Issue 1.0, April 2006 Section 364-180-N02

6.3. TCP/IP Configuration

In order to access the router’s Web GUI to begin your configuration, you must have the TCP/IP protocol installed and configured properly in your computer’s network interface card. Your computer’s TCP/IP settings must allow your computer to obtain an IP address automatically.

To connect to the Internet or configure the router via Ethernet, the TCP/IP protocol must be installed and configured correctly. Follow the steps below to determine if you have TCP/IP installed and configured correctly for Windows 95/98.

Step 1 - Check if TCP/IP is installed

1. From your computer’s desktop, double-click

on My Computer, then Control Panel, and then double-click the Network icon.

2. In the “Network” window, choose the

Configuration tab. Check that TCP/IP is installed and setup for the Ethernet NIC that is installed in your computer. If you see, for example, TCP/IP->Intel 21140 based 10/ 100mbps Ethernet Controller, that means that TCP/IP has been installed.

• If TCP/IP has not been installed for your NIC, proceed to Step 2 as below.

OR –

Issue 1.0, April 2006 Section 364-180-N02

• If TCP/IP has been installed for your NIC, continue with Step 3 - Setup TCP/IP section.

Issue 1.0, April 2006 Section 364-180-N02

Step 2 - Install TCP/IP, if necessary

Install TCP/IP now if it is not previously installed. You may need the Windows Installation CD-ROM.

1. Still in the “Network” window, click the Add

button. The “Select Network Component Type” window will appear. Select Protocol by clicking on it once. Then click Add.

3. Confirm that the TCP/IP protocol has

been correctly set up with your Ethernet. Click OK.

2. The “Select Network Protocol” window will

appear. Choose Microsoft in the “Manufacturers” panel and then TCP/IP in the “Network Protocols” panel. Click OK.

Issue 1.0, April 2006 Section 364-180-N02

Step 3 - Setup TCP/IP

1. In the “Network” window, choose the

Configuration tab. Then double-click the

TCP/IP component for your Ethernet NIC (for example, TCP/IP->Intel 21140 based 10/100mbps Ethernet Controller).

2. In the “TCP/IP Properties” window,

click the Gateway tab. Remove any installed Gateways by selecting them and clicking the Remove button.

Issue 1.0, April 2006 Section 364-180-N02

3. Click the DNS Configuration tab, and then click the Disable DNS button.

NOTE: If you disable the routers DHCP functions, you will be unable to access the router with the setting shown in step 4. You will need to choose the Specify an IP address option in step 4 and then manuall enter an IP address which is on the same subnet as the router and the Subnet Mask. For instance, assuming the router’s default IP address is

192.168.0.1, an IP address on the same subnet would be 192.168.0.2 o

4. Click the IP Address tab. Choose

Obtain an IP address automatically and click OK.

192.168.0.13 .

5. The “System Settings Change” window appears. Click Yes to reboot your system.

Issue 1.0, April 2006 Section 364-180-N02

6.4. Login to Web Configuration Tool

1. Be sure you have configured your computer’s TCP/IP settings as described in the section 6.3.

2. Launch a compatible Internet Browser. In your Browser window, type the default IP address of the router, 192.168.0.1 into the URL bar and click GO or hit the Enter key.

3. You will be prompted to enter a User Name and Password. The default User Name and

Password are:

User Name: admin Password: admin
