Noncritical light path diagnostics
Table 19 describes the light path diagnostics for noncritical events.
Troubleshooting charts
You can use the troubleshooting charts in this section to find solutions to problems
that have definite symptoms.
If you cannot find the problem in the troubleshooting charts, go to “Starting the diag-
nostic programs” on page 123 to test the server. If you have run the diagnostic test
programs or if running the tests does not reveal the problem, call for service.
Look for the symptom in the left column of the chart. Instructions and probable solu-
tions to the problem are in the right column. If you have just added new software or a
new option and your server is not working, do the following before using the trouble-
shooting charts:
• Remove the software or device that you just added.
• Run the diagnostic tests to determine if your server is running correctly.
• Reinstall the new software or new device.
On OVER SPEC The server is drawing more power
than the power supplies are rated for. Either add a power supply or remove
a device from the server.
On PS1 The first power supply has failed. Replace the first power supply.
On PS2 The second power supply has failed. Replace the second power supply.
On PS3 The third power supply has failed. Replace the third power supply.
On PS4 The fourth power supply has failed. Replace the fourth power supply.
Off None The light path diagnostics have not
detected a system error. None

occurred.
NON RED The server power subsystem is no
longer redundant. To restore redundancy, either add
another power supply to increase the
power available or remove a device
from the server to reduce the power
usage.
None Some noncritical event has occurred. Read the event log to determine the
cause.
Off None The light path diagnostics have not
detected a noncritical event. None
