Oracle^® x86 Servers Diagnostics and Troubleshooting Guide

Inspect the Internal System

1. Choose a method for shutting down the server from Main power mode to Standby power mode.

   • Graceful shutdown: Press and release the On/Standby button on the front panel. This causes Advanced Configuration and Power Interface (ACPI)-enabled operating systems to perform an orderly shutdown of the operating system. Servers not running ACPI-enabled operating systems shut down to Standby power mode immediately.

   • Emergency shutdown: Press and hold the On/Standby button for five seconds to force Main power off and enter Standby power mode.

     When the system is in Standby power mode, the System OK LED blinks.

     ---

     Caution  -  When the server is in Standby power mode, power is still directed to the service processor board and the power supply fans. To remove power completely, disconnect the AC power cords from the server back panel.

2. Remove the chassis top cover to view the server internal components.

   Refer to the server Service Manual for details.

3. Inspect the internal status indicator LEDs, as described in the Service Manual.
4. Verify that there are no loose or improperly seated components.
5. Verify that all cable connectors inside the system are firmly and correctly attached to their appropriate connectors.
6. Verify that any after-factory components are qualified and supported.

   For a list of supported PCIe cards and memory modules (DIMMs), refer to the server Service Manual and Product Notes.

7. Check that the installed DIMMs comply with the supported DIMM population rules and configurations.

   Refer to the server Service Manual for information about DIMMs.

8. Replace any faulty component.

   Refer to the server Service Manual for component remove and replace procedures.

9. To restore Main power mode to the server, that is, all components powered on, press and release the On/Standby button on the server front panel.

   When Main power is applied to the full server, the System OK LED next to the On/Standby button blinks intermittently until BIOS POST finishes, then the LED is steady on.

10. If the problem with the server is not evident, view the BIOS event logs during system startup.
