Checking the ASP Installation

This chapter describes procedures for confirming the successful hardware installation and initial configuration of the ATM switch processor (ASP), and includes the following sections:

Problems with the initial startup are often caused by an interface processor or power supply that has become dislodged from the backplane or chassis power connector during shipment. Although over-temperature conditions rarely occur at initial startup, the environmental monitoring functions are included because they also monitor DC line voltages. At the initial system boot, verify the following:

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

When these conditions are met, the hardware installation is complete. 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 solve the problem, contact a customer service representative for assistance and further instructions. Before you call, gather the following information:

Date you received the LightStream 1010 ATM switch
Chassis serial number (see label on the front of the chassis)
Type of software and release number
Brief description of the problem
Brief explanation of the steps taken to isolate and resolve the problem
Maintenance agreement or warranty information

Diagnostics

The power-on 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 and an interface is provided using the show diag power-on command. 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.

The following example shows the first few screens from the output of the show diag power-on command:

When the information about PAMs appears in the output, if a failure occurs, an "F" displays and a period (.) indicates the test passed.

Troubleshooting Flowchart

The flowchart in Figure 4-1 helps you determine which component of your LightStream 1010 ATM switch might have malfunctioned.

Module LEDs

This section describes the LEDs used to confirm and troubleshoot operation of the ASP. The LEDs on the ASP indicate the status of the ASP, fan assembly, and power supplies. The ASP LEDs are shown in Figure 4-2 and described in Table 4-1.
