Table 31 Is the internal health LED green?
Answer | Possible reasons | Possible solutions |
|
|
|
— | PPM or board power fault | Inspect the QuickFind diagnostic display |
|
| panel to determine if one of the PPMs, |
|
| processor memory boards, or system |
|
| board has experienced a power fault. |
|
| Ensure that all components are seated |
|
| properly. |
|
| If problem persists, replace the failed |
|
| component. |
|
| A PPM failure will be shown by the PPM |
|
| LED being illuminated on the specific |
|
| processor memory board. |
|
| If the processor memory board BRD LED |
|
| is amber, see “Troubleshooting a failed |
|
| processor” later in this chapter. |
|
| If the I/O power LED is amber, replace |
|
| the system I/O board. |
|
|
|
— | Thermal shutdown | If the Therm Trip LED is amber, the |
|
| system encountered an unexpected |
|
| thermal shutdown. |
|
| If one of the processor memory board |
|
| TEMP LEDs is amber, ensure that the |
|
| processor heatsink is properly attached, |
|
| all fans are functioning properly, and |
|
| that the external environment is within |
|
| specified parameters. Inspect the iLO |
|
| logs for any |
|
| warnings. |
|
|
|
Yes | — | If the internal health LED is green, see |
| Table 32. | |
