Chapter 8 Troubleshooting Troubleshooting Overview • 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 How to Set Up the Local Console 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. Table 8-4 Troubleshooting the Power Subsystem Symptom Possible Cause Power LED on the front panel and LEDs on the power supply unit are not lit, or do not remain lit continuously. Power cable not fully seated at system. Power cable not fully seated at source. Power source is faulty. Possible Solution Turn the power switch to the off position and reseat the power cable in the system. Turn the switch to the off position and reseat the power cable at the power source. Turn the switch to the off position, connect the power cable to another power source, if available, and turn the switch back on.

Troubleshooting Overview
•
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
How to Set Up the Local
Console
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.

Troubleshooting the Power
Subsystem
Symptom
Possible Cause
Possible Solution
Power LED on the front panel
and LEDs on the power supply
unit are not lit, or do not remain
lit continuously.
Power cable not fully seated at
system.
Turn the power switch to the off
position and reseat the power
cable in the system.
Power cable not fully seated at
source.
Turn the switch to the off
position and reseat the power
cable at the power source.
Power source is faulty.
Turn the switch to the off
position, connect the power
cable to another power source, if
available, and turn the switch
back on.
