Testing the Configuration

Checking the PAM Installation

This chapter describes the procedures you use to confirm that the LightStream 1010 ATM switch port adapter modules (PAMs) are operational and that the initial configuration procedures were successful. It includes the following sections:

• Troubleshooting

• Testing the Configuration

Troubleshooting

Your PAM went through extensive testing and burn-in before leaving the factory; however, if your system appears to have problems starting up, use the information in this section to help isolate the cause. Problems with the initial startup are most likely caused by an ATM switch processor (ASP), carrier module (CM), PAM, or power supply that has become dislodged from the backplane or chassis power connector.

This chapter only covers troubleshooting the PAM. Refer to the following documents to troubleshoot the LightStream 1010 ATM switch chassis installation and the ASP:

• LightStream  1010 ATM Switch Hardware Installation Guide

• LightStream  1010 ATM Switch ASP Installation Guide

When you have completed the troubleshooting procedures in these documents, continue with the PAM troubleshooting steps in the following sections:

• Read "Connecting the Interface Cables and Checking LEDs" in the individual PAM cabling and configuring chapters to check the interface connections and the PAM LEDs.

• Use the commands listed in the section "Testing the Configuration" in this chapter to test the interface connection.

When each of these conditions is met and the hardware installation is complete, you can proceed to the section "Starting the System" in the LightStream 1010 ATM Switch Hardware Installation Guide or Catalyst 5000 Series Installation Guide. If the startup sequence fails before these conditions are met, use the procedures in this chapter to isolate and, if possible, resolve the problem. If you are unable to easily solve the problem, contact a customer service representative for assistance and further instructions. To help your service provider assist you, gather the following information before you call:

• Date you received the LightStream 1010 ATM switch

• Chassis serial number (located on a label on the front of the chassis)

• Type of software and release number

• Brief description of the problem you are having

• Brief explanation of the steps you have already taken to isolate and resolve the problem

• Maintenance agreement or warranty information

Diagnostics

The power-up or hardware reset diagnostics provide full sets of test suites to test the LightStream 1010 ATM switch hardware. The test results are stored in the switch memory. Use the show diag power-on command to access the interface. If an error is detected during the test, the ASP status LED turns red. The watchdog timer timeout or software warm-start can run minimum diagnostics.

Figure 9-1 is an example of a power-on diagnostics display.

If a failure occurs, an "F" is inserted instead of the period (.) that indicates that the test passed. For example, in Figure 9-1, power supply two (PS2) failed the power-on diagnostics test.

Troubleshooting Flowchart

The flowchart in Figure 9-2 helps you determine which component of your LightStream  1010 might have malfunctioned.

Refer to the individual PAM cabling and configuration chapters for LED descriptions.

Testing the Configuration

Table 9-1 describes the commands you use to confirm the current hardware, software, and interfaces for the LightStream 1010.
