Each module contains LEDs that can be used to isolate failed components.
You can find the documentation for I/O modules at the Flex System network devices information page and for compute nodes at the Flex System compute nodes information page.
The chassis module LEDs table is a three-column table that describes the function of the LEDs on each chassis module. Column 1 identifies the LEDs. Column 2 describes the normal and fault states of the LED. Column 3 describes the user actions needed to correct faults, if indicated.
| Module name/LED | Description | User action | |
|---|---|---|---|
| Chassis management module | |||
| Fault LED | This yellow LED is lit when an error has occurred in the CMM. The system fault LED on the chassis will also be lit. | If this LED is lit, check the event log for CMM-related errors and follow the corrective actions for those events. | |
| Power supply | |||
| DC power in LED (-48 V dc supplies only) |
This green LED is not lit if there is a dc power problem. | If this LED is not lit, check the CMM event log for power-related errors and follow the corrective actions for those events. | |
| AC power in LED (200 - 240 V ac supplies only) |
This green LED is not lit if there is an ac power problem. | If this LED is not lit, check the CMM event log for power-related errors and follow the corrective actions for those events. | |
| DC power out LED | The green LED is not lit if there is an dc power problem. | If this LED is not lit, check the CMM event log for power-related errors and follow the corrective actions for those events. | |
| Fault LED | This yellow LED is lit if the power supply has failed. | If this LED is lit, check the CMM event log for power-related errors and follow the corrective actions for those events. | |
| Fan module | |||
| Fault LED | This yellow LED is lit if one of the fans in the
fan module has failed. Note: If one of the fans in the fan module fails,
the other fan will begin operating at full speed.
|
If this LED is lit, check the CMM event log for fan-related errors and follow the corrective actions for those events. | |
| Fan logic module | |||
| Fault LED | This yellow LED is lit if one of the fan logic modules fail. | If this LED is lit, check the CMM event log for fan-related errors and follow the corrective actions for those events. . | |
