Checking the ASP Installation

This chapter describes procedures for confirming the successful software installation and initial configuration of the ATM switch processor. The following topics are discussed:

Troubleshooting

Your LightStream 1010 ATM switch went through extensive testing and burn-in before leaving the factory; however, if your system has problems starting up, use the information in this chapter to help isolate the cause.

Problems with the initial startup are most likely 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 supply 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 conditions are met, the hardware installation is complete, and you should proceed to the chapter "Configuring the LightStream 1010 ATM Switch Processor." 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 to help your service provider assist you:

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 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 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 may run minimum diagnostics.

Figure 5-1 is an example of a sample display of the first few screens from the show diag power-on command.

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 system, which includes the fan assembly and power supplies and the ASP. The ASP LEDs are shown in Figure 5-3 and described in Table 5-1.

LED	Description
Status	The switch performs a series of self-tests and diagnostic tests. If all the tests pass, the status LED is green. If any test fails, the status LED is red. During system boot or with a disabled module, the LED is orange.
Fan	Indicates whether or not the fan is operational. If the fan is operational, the fan LED is green. If the fan is not operational, the fan LED is red.
PS 0, Left Bay	If the power supply is operational, the PS0 LED is green. If the power supply is installed but not operational, the PS0 LED is red. If the power supply is not installed, the PS0 LED is off.
PS 1, Right Bay	If the power supply is operational, the PS1 LED is green. If the power supply is installed but not operational, the PS1 LED is red. If the power supply is not installed, the PS1 LED is off.
Link	Green---The Ethernet port is operational. Off---No signal is detected.
RX (Receive)	Off---No signal received. Flashing green---Ethernet packets being received: pulse rate increases with data rate.
TX (Transmit)	Off---Not transmitting. Flashing green---Ethernet packets being transmitted: pulse rate increases with data rate.
