7-6 CHAPTER 7: TROUBLESHOOTING

Group 2 Diagnostic

The Group 2 diagnostic (Adapter Wrap Test) is a wrap test that causes all user-transmitted data to be sent and received without going to the network.

A lobe cable must be connected from the selected adapter to a retiming concentrator or MAU for all tests. A lobe cable is the section of cable that attaches a ring station or network device to a MAU or wiring hub.

Running the Diagnostic Tests

The Configuration and Diagnostic Program can be started from the menus or the DOS command line. For command line instructions, see the INSTRUCT.TXT file in the \DIAG subdirectory on the TokenDisk diskette.

If you have already installed the network driver, you need to reboot and press [F5] or use a DOS diskette to bypass the drivers before you run the diagnostic program. Use a DOS diskette if you are running DOS 5.0 or earlier. If you are running Windows NT, boot the DOS partition or boot from a DOS diskette to run the diagnostic program. If you are running Windows 95, exit Windows 95 and restart the PC in MS-DOS mode.

These instructions assume that the TokenDisk diskette is in the floppy drive that is active.

1To start the diagnostic program, type:

3TOKDIAG

2From the Test pull-down menu shown in Figure 7-3, select Run Tests.

The Run Tests dialog box appears, similar to the one shown in Figure 7-4.

3Press [Enter] to start the tests.

Each test is set up to run once unless you specify otherwise. The test results are displayed on the screen with “Passed” or “Failed” in the Results column.
