Troubleshooting the system status LED faults
The system status LED on the control panel on the front panel of the media server
compute node signals valuable health information about the unit. This LED is
located just below and to the left of the power LED and button. During normal
operation the system status LED is a solid green. The LED changes states when
the system detects a problem. The following table describes the different states
the system status LED can assume. Steps you can take to troubleshoot a change
of status are provided after the table.
