Confirming the Installation

This chapter describes troubleshooting procedures used to confirm that the hardware and software installation and configuration procedures were successful.

Troubleshooting

Your LightStream 1010 ATM switch 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 chapter to help isolate the cause. Problems with the initial startup will most likely be caused by an interface processor or power supply that has become dislodged from the backplane or chassis power connector. Although over-temperature conditions rarely occur at initial startup, the environmental monitoring functions are included because they also monitor DC line voltages. This manual covers the system hardware installation only. At the initial system boot, you should verify the following:

The power supplies are installed properly and are supplying power to the system.
The system fan assembly is operating.
The system software boots successfully.
The ATM Switch Processor (ASP) and all Carrier Modules (CMs) and port adapter modules (PAMs) are properly installed in their slots and each is initialized without problems.

When each of these conditions is met, the hardware installation is complete, and you should proceed to the chapter "Configuring the LightStream 1010 ATM Switch." 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. Before you call, have the following information ready to help your service provider assist you as quickly as possible:

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 for the LightStream 1010 ATM switch hardware. The test results are stored in the switch memory and an interface is provided using the show diag power-on command. If an error is detected during the test, the ASP STATUS LED is turned on RED. The watchdog timer timeout or software warm-start may run minimum diagnostics.

Figure 5-1 is an example of a power-on diagnostics display.

If a failure occurs, an "F" is inserted instead of the period (.) which indicate that the test passed. For example, in Figure 5-1, power-supply two (PS2) failed the power-on diagnostics test.
