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.
