When LEDs are lit to indicate an error, they remain lit when the server is turned off, provided that the server is
still connected to power and the power supply is operating correctly.
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 33.
If an error occurs, view the light path diagnostics LEDs and 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 event log or system-error log might be required.
The following illustration shows the operator information panel on the front of the server.

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

technician.
• Go to the Lenovo support website at http://www.lenovo.com/support to check for technical information,
