Before you work inside the server to view light path diagnostics LEDs, read the safety information “Safety”
on page v and “Handling static-sensitive devices” on page 31.
If an error occurs, view the light path diagnostics LEDs in the following order:
1. Look at the operator information panel on the front of the server.
• If the check log LED is lit, it indicates that an error or multiple errors have occurred. The sources of
the errors cannot be isolated or concluded by observing the light path diagnostics LEDs directly. A
further investigation into IMM2.1 system-event log or system-error log might be required.
• If the system-error LED is lit, it indicates that an error has occurred; go to step 2.
The following illustration shows the operator information panel.

The following table describes the LEDs on the operator information panel and suggested actions to
correct the detected problems.
• Follow the suggested actions in the order in which they are listed in the Action column until the
problem is solved.
• If an action step is preceded by '(Trained technician only)', that step must be performed only by
a Trained technician.
• Go to the IBM support website at http://www.lenovo.com/support to check for technical information,
hints, tips, and new device drivers or to submit a request for information.
