Problem Solving Using a Subsystems Approach

Identifying Startup Problems

Startup problems are commonly due to the source power or to a poor cable connection.

When you start up the SCE 2000 platform for the first time, you should observe the startup sequence described in the Starting the SCE 2000 Platform (on page 7-1). This section contains a more detailed description of the normal startup sequence and describes the steps to take if the system does not perform that sequence as expected. LEDs indicate all system states in the startup sequence. By checking the state of the LEDs, you can determine when and where the system failed in the startup sequence. Use the following descriptions to isolate the problem to a subsystem, and then proceed to the appropriate sections to try to resolve the problem.

When you start up the system by turning on the power supply switch, the following should occur:

•You should immediately hear the fans operating.

•When all LEDs come on to indicate that the system has booted successfully, the initial system banner should be displayed on the console screen. If it is not displayed, see Connecting the Local Console (on page 5-1) to verify that the terminal is set correctly and that it is properly connected to the console port.

•If the banner is displayed, but the Status LED is flashing orange, indicating a warning state, check the user log:

At the prompt, type: more user log

If any of the following warning messages appear, turn the SCE 2000 platform off and call technical support.

•"voltage problem:"

•"fans problem"

•"abnormal raise in interior temperature:"

If the following warning message appears, delete unneeded files from the disk.

•“insufficient disk space:”

Troubleshooting the Power Subsystem

Check the following to help isolate a problem in the power subsystem. In the normally configured SCE 2000 platform with redundant power supply units, it is unlikely that the device will not start at all. However, at startup it should be verified that both power supply units are operational, and therefore the following steps should be followed if one of the Power LEDs on the front panel remains unlit when the SCE 2000 platform is powered up.

Note If the system powers off due to an environmental shutdown, wait at least one minute before manually rebooting the system, or it will pause indefinitely.
