Chassis module LEDs
Each module contains LEDs that can be used to isolate failed components.
Note
To find descriptions and actions for LEDs on I/O modules or compute nodes, see the documentation that comes with the device.
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 Flex System Manager event log for CMM-related errors and follow the corrective actions for those events. | |
| Flex System Manager | |||
| Fault LED | This yellow LED is lit when an error has occurred in the Flex System Manager. The system fault LED on the chassis will also be lit. | If this LED is lit, check the Flex System Manager event log for Flex System Manager-related errors and follow the corrective actions for those events. See the Flex System Manager Installation and Service Guide for more information. | |
| Power supply | |||
| AC power LED | This green LED is not lit if there is an ac power problem. | If this LED is not lit, check the Flex System Manager event log, if installed, or the CMM event log for power-related errors and follow the corrective actions for those events. | |
| DC power LED | The green LED is not lit if there is an dc power problem. | If this LED is not lit, check the Flex System Manager event log, if installed, or 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 Flex System Manager event log, if installed, or 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 Flex System Manager event log, if installed, or 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 Flex System Manager event log, if installed, or the CMM event log for fan-related errors and follow the corrective actions for those events. . | |
