Use this information as a guide to the LEDs on the IBM® Power® System S812LC (8348-21C) system.
The LEDs indicate various system status. If the part does not have a problem indicator LED, you can use a troubleshooting program such as impitool to identify the issue.
These LEDs are located at the front (as shown in Figure 1).
