Viewing error logs from the diagnostic programs

Start the diagnostic programs; select

Hardware Info

from the top of the diagnostic

programs screen; select

System Error Log

from the list that appears; then, follow

the instructions on the screen. See “Starting the diagnostic programs” on page 23

for more information.

Light path diagnostics

Many errors are first indicated by the illumination of the information LED or

system-error LED in the operator information panel on the front of the server. If one

or both of these lights are lit, one or more lights elsewhere in the server might also

be lit and can direct you to the source of the error.

This light path diagnostics feature provides a path that you can follow in three

phases to help identify the source of an error. The lights are designed to be

followed in an orderly progression, depending on the error.

Note:

Read “Safety information” on page 147 and “Handling static-sensitive

devices” on page 30.

The lights are viewed in the following order:

Begin on the front panel by checking the operator information panel.

The information LED indicates that information concerning a sub-optimal

condition in the server is available in the system-error log.

The system-error LED indicates that an error has occurred.

If the system-error LED on this panel is lit, go to step 2.

Then, check the system service label. This label gives an overview of internal

components that correspond to the LEDs on the light path diagnostics panel.

This information, combined with the information in the table “Light path LED

errors” on page 93, can often provide enough information to correct the

indicated error.
