1 - INSTALLATION

The router is an Ethernet Bridge/Router that provides bridging, IP/IPX routing, and compression over a frame relay permanent virtual circuit or a PPP leased line circuit..

The following instructions provide a quick set-up guide for installation of the router

Unpack the unit

Rough handling during shipment can damage electronic equipment. As you unpack the router, carefully check for signs of damage. If damage is suspected, contact the shipper. Save the box and all packing material to protect the router should it ever need to be moved or returned for service.

Check the packing slip that identifies the components and the LAN connector. The connectors on the rear of the router provide all external connections to the router.

Select a Site

Place the router in a well-ventilated area. The site should maintain normal office temperature and humidity levels. Air vents located on the rear of the router must have an inch or so of clearance from any object. Units should not be stacked.

Installation

UNIVERSAL WAN

CSU-DSU

T1/E1

Identify the Connectors

Each unit is configured with both straight (MDI) and crossed over (MDI-X) 10BaseT LAN connectors; the router will auto-sense between the two. Only one connector may be used at a time.

The router is produced with four different WAN interface modules: V.35, CSU-DSU, Universal WAN or T1/E1. The type of module in a unit may be determined by looking at the label over the WAN connector on the back panel.

V.35

Figure 1 - 3 Rear View of the V.35 router

Figure 1 - 4 Rear View of the T1/E1 router

Installation

Connect to the Console

Connection to the router operator’s console is made through the RJ-45 connector labeled CONSOLE on the back of the router. A RJ-45 cable and RJ-45 to DB9 (female) converter are provided for connection to a DB9 (male) connector.

Connect the console port of the router to a computer running an asynchronous communication package or a standard asynchronous terminal. The router supports autobaud rates at 1200, 2400, 9600 or 19,200 bps. The router is managed through the use of “hotkey” Menus.

Appendix C provides the pinout information for the console connector and the DB9 to RJ45 converter.

Make the LAN Connections

Connect the router to the LAN with the available LAN interface cable. The router may be connected directly to a wiring hub or Ethernet

switch by using the MDI LAN port and a standard 10BaseT cable. The router may be connected directly to a computer network card by

using the MDI-X LAN port and a standard 10BaseT cable.

Make the WAN Link Connection

The Universal WAN module may be selected to operate as a V.11, V.35, RS232, or EIA530 interface. The Universal WAN interface module uses a DB25 connector. Be sure to secure the cable connector to the router and the communications equipment with connector screws to prevent accidental disconnection.

WARNING: ensure that the connector cable used with the Universal interface module has the correct pinouts for the operational mode selected for the interface (V.11, V.35, RS232, or EIA530). Using the incorrect cable connector for the operational mode selected may cause permanent damage to the interface module. Please see Appendix D for pinout assignments.

Note: When the router is initially powered up, the Universal WAN will have the default type of “none”. Before the link can be used, it

Installation

must be configured to the type of connection service that will be used; please see the following section for this procedure.

The V.35 module and Universal WAN module in V.35 mode require interface converters that convert from a DB25 connector to a male 34 pin (V.35) connector used for the V.35 service interface. Be sure to secure the cable connector to the router and the communications equipment with connector screws to prevent accidental disconnection.

The T1/E1 and LX411 CSU-DSU interfaces connect with a standard RJ-45 (RJ-48C specification for T1/E1, RJ-48S specification for CSU/DSU) connector

After the router is powered up and the router has established communications with its partner across the WAN, the “Tx” LED will turn green.

Installation

Power Up the router

Once the LAN and Link connections are made and the console is connected to a terminal, you are ready to power-up the router. Connect the DC power cord from the supplied power supply to the back of the router and plug the power supply into the AC wall outlet.

Observe the LEDs as the router powers up. The LEDs will go through a flashing pattern as the power-up diagnostics are performed. After the power-up diagnostics are finished, the Power LED will go from red to green.

The console will also display testing and initialization messages as it performs these tasks (if this is the first time the router has been powered up on this console, the display may be unreadable until the next step is performed).

Enter at least one [RETURN] (up to three if necessary) in order for the router to determine the baud rate of the terminal used for the console (i.e., autobaud). The following information will now be seen on the console connected to the router :

Terminals supported:

ansi, avt, ibm3101, qvt109, qvt102, qvt119, tvi925, tvi950, vt52, vt100, wyse-50, wyse-vp, teletype Enter terminal type:

Select the terminal type being used if listed and enter its name (in lower case) at the prompt, or choose the terminal type teletype if your terminal is not listed. This terminal type operates in scroll mode and may be used successfully until a custom terminal definition is created.

At the login screen type a 1 and the default password to enter the menu system of the router. The default password is BRIDGE (case sensitive) and should be changed if security is desired.

With the options of the built-in menu system, the router may be configured to operate within your environment.

2 - TYPICAL APPLICATIONS & HOW TO CONFIGURE THEM

The router is an Ethernet Bridge/Router that supports frame relay RAW 1490 permanent virtual circuits, frame relay encapsulated PPP permanent virtual circuits and PPP leased lines. This section will describe how to set up the router using each of its networking functions.

The router may be configured as a simple Ethernet bridge, an Ethernet IP router, an Ethernet IPX router, or a combination of the three. When operating the router as a combination bridge/router simply configures each of the components separately.

: The configuration options described within this section are only for initial

set up and configuration purposes. For more information on all of the configuration parameters available, please refer to the router PPP Menus Reference Manual file on the accompanying CD-ROM.

Important: The router uses FLASH memory to store the

configuration information. Configuration settings are stored to FLASH memory after there has been 30 seconds of idle time. Idle time is when there is no selection or modification of the values in the built-in menu system. If you wish to save the configuration immediately, enter “=” to jump to the main menu, then select option “6” to save the configuration.

Applications

Managing the router Using Menus

This section describes the minimum configuration parameters required when setting up the router. Each of the configuration scenarios requires setting of operational parameters on the router. The built-in menu system of the router is used to configure the unit.

When navigating around the menu system, a new menu or an option may be chosen by simply typing the number associated with the option that you wish to choose. The menu system operates on a “hotkey” principal. Each menu option may be chosen by simply typing the number associated with that option. The router will accept the choice and act on it immediately.

The menu system consists of different menu levels each containing new configuration options. Navigation back out of a nested menu is easily accomplished by pressing the tab key. The tab key takes you to the previous menu level. If you wish to move from your current menu location directly to the main menu simply press the equals “=” key.

When choosing menu options that will toggle between values, simply pressing the number associated with that option will cause the options value to change. Each successive selection of the option will cause the options value to change.

Some menu options require input from the operator. When selecting an option that requires a value, the menu system will display the range of values acceptable and a prompt symbol “>”. Simply enter the new value at the prompt symbol and press enter. Should you make an error in entering the new value, the [BACKSPACE] key (for most terminals) deletes the most recently entered characters.

Applications

frame relay provider.

Basic Frame Relay Configuration

North American routers are configured to have frame relay enabled as the default setting. With frame relay enabled, the router will communicate over WAN connections to other frame relay units via frame relay Permanent Virtual Circuits (PVC). From 1 to 40 PVC’s may be defined to connect to other frame relay units. Before the router can establish a PVC connection to another frame relay router, at least one PVC must be defined. The router is pre-configured to query the frame relay service to auto-learn the required parameters; they may also be set manually.

The DLCI (Data Link Connection Identifier) number for the PVC is assigned by the frame relay service provider. The PVC must be defined on the physical link on the router. Refer to the following diagram that shows three router units connected together with a PVC being configured on each unit. The configuration of the PVCs within the frame relay cloud is controlled by the frame relay service provider.

DLCI numbers assigned for these PVCs from the

The router will request confirmation of the change, enter “yes”.

For an router with a CSU-DSU interface, the default clock speed that the router will expect to receive from the DCE link is 64Kbps. If the DCE link is 56 Kbps, then the Link Speed value must be reset to 56 here.

Applications

Auto Learning the Frame Relay Configuration

The router is pre-configured to query the frame relay service to autolearn the LMI type and the PVC DLCI numbers. This auto-learn function allows the router to be plugged into the frame relay service and auto-learn the PVC configuration to become operational without further manual configuration.

Manual configuration is also allowed by modifying the options within each Remote Site Profile and the individual link configuration menus.

When the router first starts up it will query the frame relay service to try to determine the LMI type. Once the LMI type is determined, the PVC configurations will be known from the full status enquiry messages. If the DLCI numbers of the PVC’s on your service are determined during this learning process, the router will automatically create a remote site profile for each PVC. The automatically created remote site profiles will be named “LinkxDLCIyyy” where x is the physical link number the PVC is on and yyy is the DLCI of the PVC.

If during this learning process the maximum number of remote sites (40)

has been reached, the router will prompt you that there are no remote sites available. A new remote site cannot be auto-created unless one of the existing remote sites is manually deleted.

Applications

Manual Configuration - LMI Type

The LMI Type option allows you to manually specify the type of Link Management Interface in use by the Frame Relay service provider for the Frame Relay service.

When the LMI type is set to none, the router simply creates frame relay packets and sends them on the defined PVC’s. The links are not checked for errors. There is no congestion control checking. The link is only monitored for control signals.

To manually configure the LMI type the Auto-Learning option must be disabled.

Applications

“Quick Start” Frame Relay

Since the router auto-learns the frame relay configuration, only a couple of parameters need to be configured before the unit is fully operational as an IP router for frame relay.

Upon initial start up, the router is pre-configured to query the frame relay service to auto-learn the LMI type and the PVC DLCI numbers. The router will then automatically create a remote site profile for each PVC.

Within each of the remote site profiles automatically created Bridging, IP routing, and IPX routing are all set to “enabled”. Because each of these options are enabled by default and the automatically created remote site profiles will establish a PVC connection to the remote site routers, the router will bridge and IPX route data without any user configuration. Because an IP router requires an IP address, the router must be configured with an IP address before IP routing is fully operational.

To configure an IP address for the router, use the IP address option.
