Using This Manual
This Installation and Applications Guide provides the basic information
required to initially set up and configure the router. This guide is organized
into the following sections:
“Installation” provides instructions for installing the router.
“Typical Applications & How to Configure Them” provides
simple configuration examples for typical applications in which the
router might be used. The applications described in this document are
for example only and provide a method of quick configuration of the
router. For more complete information on all of the configuration
parameters available, please refer to the PPP Menu Reference Manual
on the accompanying CD-ROM.
“Introduction to Filtering” provides an introduction to the pattern
filtering options of the router. Several examples of typical pattern
filters are also provided.
”Menu Trees” provides a graphical tree type overview of the
structure of the built-in menu system of the router. All of the
configuration is performed using the options provided in the menu
system. The Menu Tree is like an index to the menu options.
“Configuration Pages” provides a place to note the current
configuration of the router for future reference. If a replacement unit
is required, the configuration may be quickly modified to be the same
as the existing unit.
“Octet Locations on Ethernet Frames” provides a graphical
representation of the various common Ethernet frames that the router
will bridge or route. When defining a pattern filter, these frame
displays indicate the offset values to use in order to define the pattern
filter correctly.
“Servicing Information” provides information on opening the case
and changing the straps.

Using the Electronic Reference Manual
The router Reference Manuals are provided as Adobe Acrobat PDF

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
6
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.

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

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
9
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.
Login and Enter the Required Configuration
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.
Refer to the router PPP Menus Reference Manual file on the
accompanying CD-ROM for a complete description of all the Menu
Options.

Mandatory Configuration
The router requires a minimum amount of mandatory configuration in
order to operate. The following table identifies the configuration
parameters that must be defined for proper operation under the
operational states shown in the table.

complete description of all the Menu Options.
Other options may be changed depending upon specific installation
configurations. Refer to the menu tree in Appendix A for a reference
of the menu structure and options.

Setting the Link Interface Type
(Universal WAN only)
The Universal WAN Interface must be configured to match the service
to which it will be connected.
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/X.21, V.35, RS232/V.24, or
RS530/RS422). 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.
