Setting Up the GT 50 Hardware

This chapter provides the steps for setting up GT 50 connections. It includes the following topics:

GT 50 Connections

Connecting Your GT 50 to Your PC

Connecting Your GT 50 to Your Ethernet

Connecting Your GT 50 to the Internet or Another WAN

Connecting Your GT 50 to a Power Source

Testing Your Connections

GT 50 Connections

 Your GT 50 back panel has connectors for connecting your GT 50 to

Connecting Your GT 50 to Your PC

 You can connect the GT 50 to your PC directly or through an Ethernet hub by setting the GT 50 PC/Hub crossover switch to either PC or Hub. For initial configuration or if you have only one PC, you may want to connect your PC directly to your GT 50.

To connect the GT 50 directly to your PC . . .

1. Connect one end of a 10BaseT straight-through cable to the LAN connector on the GT 50 back panel.
2. Connect the other end of the cable to the RJ-45 Ethernet connector on your PC.
3. Set the PC/Hub crossover switch on the GT 50 back panel to PC.

Connecting Your GT 50 to Your Ethernet

Use a 10BaseT Ethernet cable to attach your GT 50 to an Ethernet 10BaseT hub. When you connect your GT 50 to the same Ethernet hub that your PC is connected to, the GT 50 can communicate with the PC via the hub.

1. Connect one end of the 10BaseT cable to the LAN connector on the GT 50 back panel. The maximum length for a 10BaseT cable is 100 meters (approximately 328 feet).

2. Connect the other end of the cable to an Ethernet (10BaseT) hub.
3. Set the PC/Hub crossover switch on the GT 50 back panel to Hub.

Connecting Your GT 50 to the Internet or Another WAN

 You can connect your GT 50 to the Internet or another WAN by using the Point-to-Point Protocol (PPP) over a dialup telephone line.

To connect the GT 50 to a PPP WAN, use a modem. The GT 50 supports asynchronous modems.

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 Your GT 50 to a WAN Using PPP

Use an RS-232 straight-through cable to attach your GT 50 to a modem, and use a telephone cable to attach your modem to the telephone line.

1. Connect one end of an RS-232 cable to the RS-232 connector on the GT 50 back panel.
2. Connect the other end of the RS-232 cable to a modem.
3. Connect one end of a telephone cable to the modem and the other end to the telephone line.

Connecting Your GT 50 to a Power Source

1. Connect the DC jack end of the power cord attached to the power supply to the +5V connector on the back of your GT 50.
2. Plug the power supply into a grounded wall outlet (or power strip). How you do this depends on whether your power supply has an AC plug or needs an AC power cord.

3. Set the GT 50 1/0 switch to 1 (the ON position) to start the GT 50. When the PWR light on the front of your GT 50 is on, the GT 50 is receiving power.

Testing Your Connections

 After you configure your GT 50 and the GT 50 is connected to the Internet, you can test the connections by running Ping or Telnet from your PC to a remote host. Ask your Internet Service Provider (ISP) for the IP address or name of a remote host that you can communicate with through your GT 50.

Note: The location of the Ping and Telnet utilities varies from system to system, depending on your operating system and the vendor's TCP/IP stack.

For Windows 95 or Windows NT 4.0

1. Click the Start button.
2. Choose the Run... command.
3. Enter ping or telnet and the remote host's IP address in the Open field.

For example: ping <remote host IP address>
4. Click OK.
If Ping succeeds, you receive a message indicating that the remote host is reachable, or you receive lines of output showing that your PC is receiving data back from the remote host. If Telnet succeeds, a Login prompt displays for the system you have reached.

To end your Telnet session . . .

1. Click the Connection menu.
2. Click Disconnect.
3. Click the File menu.
4. Click Exit.
