Troubleshooting

For both types of tests, normal operation is indicated when generated packets are received back (after looping) without errors. For remote loopback tests, the ATX creates LLC Type 1 test packets for LANs and PPP echo-request packets for WANs and UARTs.

Both types of loopback tests can be initiated by the NMS, and test results are reported to the NMS.

5.2.2Diagnostic Results

The ATX diagnostic results are indicated in two ways: by observing the front panel LEDs (which are explained later in this chapter) or by reading NMS trap messages. Both power-up and loopback diagnostics produce traps, which are sent to the NMS and may be logged for future reference. In some cases it may be more convenient to simply observe the LEDs, but in most cases traps provide more information. There are no LEDs for the loopback tests—the results of these tests must be observed (i.e., accurate packet transmission) or read using an NMS (i.e., examine traps).

5.3 TROUBLESHOOTING

5.3.1If the Module Fails to Power Up

If the Token Ring module fails to power up when the ATX is on and functioning properly:

1.Check the status of ports using LCM.

2.Reset the Token Ring module and observe the power-up sequence again.
