Chapter 3 Setting Up the GT 80 Hardware

This chapter provides the steps for setting up GT 80 connections. It includes the following topics:

GT 80 Connections

Connecting Your GT 80 to Your PC

Connecting Your GT 80 to an Ethernet

Connecting Your GT 80 to the Internet or Another WAN

Connecting Your GT 80 to a Power Source

Mounting Your GT 80 on a Wall

GT 80 Connections

Your GT 80 back panel has connectors for connecting your GT 80 to

two Ethernet local area networks (LANs) via its ETH connectors
the Internet or other wide area network (WAN) via its RS232-DTE connector
a PC or workstation via its Console connector

Note: The crossover switch allows you to set your GT 80 to communicate with either your PC or an Ethernet hub over the ETH1 port. This switch does not operate with ETH2.

Connecting Your GT 80 to Your PC

Your GT 80 provides two ways of connecting your GT 80 to your PC:

Via the Console port
Via one of the Ethernet ports

Via the Console Port

To connect a PC or terminal directly to the router, use the supplied 9-pin to 9-pin null-modem cable and, if needed, the 9-pin to 25-pin adapter. You can communicate with your GT 80 via its Console port. The following figure shows how to connect a PC or terminal directly to the router.

Via the Ethernet Ports

You can connect the GT 80 to your PC via either of its two Ethernet ports.

If you are connecting your GT 80 to your PC via ETH1,

: 1. Connect one end of a 10BaseT straight-through cable to the ETH1 connector on the GT 80 back panel.
: 2. Connect the other end of the 10BaseT cable to the Ethernet connector on your PC.
: 3. Set the PC/Hub crossover switch on the GT 80 back panel to PC.

If you are connecting your GT 80 to your PC via ETH2,

: 1. Connect one end of a 10BaseT crossover cable to the ETH2 connector on the GT 80 back panel.
: 2. Connect the other end of the 10BaseT cable to the Ethernet connector on your PC.

Note: The crossover switch on the router's back panel does not work with the ETH2 connection.

Connecting Your GT 80 to an Ethernet

Use a 10BaseT cable to attach your GT 80 to an Ethernet 10BaseT hub. When you connect your GT 80 to the same Ethernet hub that your PC is connected to, the GT 80 can communicate with the PC via the hub.

: 1. Connect one end of the 10BaseT cable to one of the ETH connectors on the GT 80 back panel.
: 2. Connect the other end of the cable to an Ethernet (10BaseT) hub.

Notes:

Your GT 80 is capable of connecting to two separate LANs.
If you are connecting to the ETH1 port, use a straight-through cable and set the PC/Hub crossover switch on the GT 80 back panel to Hub.
If you are connecting to the ETH2 port, use a 10BaseT straight-through cable to connect a hub and a crossover cable to connect a PC.

Connecting Your GT 80 to the Internet or Another WAN

You can connect your GT 80 to the Internet or another WAN by using the Point-to-Point Protocol (PPP) over either a dialup telephone line or a dedicated (leased) line or by using a Frame Relay network. To connect the
GT 80 to a

PPP WAN, use a modem. The GT 80 supports both asynchronous and synchronous modems.
Frame Relay WAN, use a Channel Switching Unit/Digital Switching Unit (CSU/DSU). The GT 80 works with any of the major CSU/DSU products on the market.

The type of WAN cable you use depends on the interface type that the equipment you connect to supports. To connect to a device that has a Data Communications Equipment (DCE) connector, use a Data Terminal Equipment (DTE) cable. To connect to a device that has a DTE connector, use a DCE cable.

Note: Most modems have 25-pin RS-232 DCE interfaces and require a straight-through cable.

Connecting to a CSU/DSU varies from vendor to vendor. Some vendors support RS-232 DCE interfaces, but many only have a V.35 connection. These devices require an external V.35 to RS-232 converter and the appropriate conversion cables.

Connecting Your GT 80 to a WAN Using PPP

Use an RS-232 straight-through cable to attach your GT 80 to a modem, and use an RJ-11 cable to attach your modem to the telephone line.

: 1. Connect one end of an RS-232 cable to the RS-232 DTE connector on the GT 80 back panel.
: 2. Connect the other end of the RS-232 cable to a modem.
: 3. Connect one end of an RJ-11 cable to the modem and the other end to the telephone line.

Connecting Your GT 80 to a WAN Using Frame Relay

The GT 80 WAN connector (on the back panel) is an RS-232 DTE connector. If the CSU/DSU you are using to connect to Frame Relay has a V.35 connector, you need to use an RS-232 to V.35 converter as shown in the following figure.

: 1. Connect the converter's RS-232 connector to the WAN connector on the GT50.
: 2. Connect the converter's V.35 connector to the V.35 connector on the CSU/DSU.
: 3. Connect the CSU/DSU to the Frame Relay network switch.

Note: If the CSU/DSU you are using has an RS-232 connector, you only need an RS-232 cable to connect the GT 80 to the CSU/DSU.

Connecting Your GT 80 to a Power Source

: 1. Connect the DC jack end of the power cord (supplied by OpenROUTE Networks with the power supply) to the +5V connector on the back of your GT 80.
: 2. Connect an AC power cord to the power supply.
: 3. Plug the power cord into a grounded wall outlet (or power strip).
: 4. Set the GT 80 ON/OFF switch to ON (the Up position) to start the GT 80. When the PWR light on the front of your GT 80 is on, the GT 80 is receiving power.

Mounting Your GT 80 on a Wall

Your GT 80 comes with brackets on its underside for mounting the unit on a wall. To mount your GT 80 on a wall,

: 1. Mount two Phillips or flat-blade #4 (2.5mm) pan-head screws 6.5" (165mm) apart on the wall at the desired height.
: 2. Leave a 0.2" (4.57mm) gap between the screw head and the wall.
: 3. Push the screw heads through the bracket holes on the underside of the
GT 80 and slide the GT 80 chassis down until it sits firmly on the screwheads.
