If an error occurs, view the server LEDs in the following order:
1. Check the control-panel assembly on the front of the server. If the system-error LED is lit, it indicates
that an error has occurred.
2. Check the front and rear of the server to determine whether any component LEDs are lit.
3. Remove the server cover and look inside the server for lit LEDs. Certain components inside the server
have LEDs that will be lit to indicate the location of a problem. For example, a DIMM error will light the
LED next to the failing DIMM on the system board.
4. Look at the system service label inside the cover of the server, which gives an overview of internal
components. This information can often provide enough information to correct the error.
The following table describes the LEDs on the system board 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 Lenovo 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.
