Troubleshooting the Cisco 200

This appendix provides general guidelines for troubleshooting the Cisco 200. It also contains a troubleshooting worksheet that lists the information you should have available when seeking technical assistance. This appendix contains the following sections:

Service and Support

For information about obtaining technical assistance with your Cisco 200 product, refer to the Cisco Information Packet, which shipped with your product.

Troubleshooting Checklist

The following list of guidelines will help ensure that the Cisco 200 will operate properly:

  • When you run INSTALL or SETUP, do not enter any non-numeric characters in the telephone number entry display.

  • If you use the CONNECT.BAT file, enter the name of the connecting router at the end of the line. The router name is case-sensitive. For example, if the router name is "HEADQUARTERS" in all capital letters, you must enter:

CONNECT HEADQUARTERS
not:
CONNECT Headquarters
  • If you manually load the Cisco 200, the name of the connecting router must appear at the end of the ISDN200 statement. The router name is case-sensitive. For example:

ISDN200 HEADQUARTERS
not:
ISDN200 Headquarters
  • The node MAC address must be unique on the network. Check with your network administrator.

  • Select the correct ISDN protocol (for example, NI1).

  • The ISDN Adapter must be firmly seated and properly connected, and the jumpers must be set correctly.

  • Use a properly configured NT1 if required by your ISDN provider.

  • Do not use a terminal adapter; the ISDN Adapter has a built-in terminal adapter.

  • Select the proper ISDN line speed (56 kbps or 64 kbps). Verify that the line speed is the same as the line speed of the connecting router.

  • When configuring the connecting router, if you are using a 56 kbps ISDN line, include the SERVICE=DATA56 statement in your router's configuration file.

  • If you are using CHAP authentication, make sure you are using the correct password. Remember, passwords are case-sensitive.

  • Enter the correct SPID, directory name, or both, if required for your ISDN protocol.

  • All phone numbers must be correct.

  • Ensure that the network protocols you want to use are enabled. Check the ISDN200.CFG file to make sure there is a semicolon (;) in the first position of the line for all the protocols you want to use.

  • Ensure that a dialer map is present and configured properly on the connecting router.

Blank Screen and Other Hardware Problems

If the screen is blank, or if your workstation seems to be executing commands slowly, the Cisco 200 software with VLM or NETX loaded might be trying to determine whether the command you entered is a NetWare or a DOS command. Therefore, it will bring up a suspended ISDN connection before executing a command. Be sure you unload VLM or NETX when you finish using the services of the remote file server.

Cannot Connect to Router

Ensure that there are no duplicate network addresses. Addresses are usually assigned by the network administrator.

Troubleshooting the Connecting Router Configuration

The following example illustrates a connecting router configuration for a Cisco 2503 router using PPP multilink with PPP callback and the DSS1 protocol. Have your system administrator use this example if you are having problems connecting using your Cisco 200 and suspect a router configuration problem may be the cause. The lines in bold-face type relate to your installation and are explained in detail in the text following the example.

Using NETX.EXE with Windows or Windows for Workgroups

If you are using NETX.EXE with Windows or Windows for Workgroups, you need the following files:

  • LSL.COM (supplied with Cisco 200 software and installed into the Cisco 200 directory)

  • IPXODI.COM

  • NETX.EXE

These files should be provided by your system administrator.
