Internally Inspect the Server

  1. Choose a method for shutting down the server from main power mode to standby power mode.
    • Graceful shutdown: Press and release the Power 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 Power button for four seconds to force main power off and enter standby power mode.

      When main power is off, the Power/OK LED flashes.


      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. Access your server's internal components.

    Refer to your installation guide or service manual for details.

  3. Inspect the internal status indicator LEDs as described in your installation guide or 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 PCI cards and DIMMs, refer to your service manual.

  7. Check that the installed DIMMs comply with the supported DIMM population rules and configurations as described in your service manual.
  8. Reassemble your server.

    Refer to your installation guide or service manual for details.

  9. To restore full power mode to the server, (all components powered on), press and release the Power button on the server front panel.

    When main power is applied to the full server, the Power/OK LED next to the Power button blinks intermittently until BIOS POST finishes.

  10. If the problem with the server is not evident, you can try viewing the power-on self-test (POST) messages and BIOS event logs during system startup.

    See BIOS POST or refer to the your service manual for more information about POST and BIOS event logs.
