Diagnosing server problems

About this task

Use this sequence of tasks to diagnose a problem in the server.

Procedure

  1. Check the system-error LED on the operator information panel. If this LED lights up or flashes, check the light diagnostic panel.
    ImportantImportant

    When you slide the light path diagnostics panel out of the server to check the LEDs, do not run the server continuously with the light path diagnostics panel outside of the server. The panel should be outside of the server for only a short time. The light path diagnostics panel must remain in the server when the server is running to ensure proper cooling.

  2. Check the power supply LEDs and hard disk drive LEDs.
  3. If the LED lights up for a component that can be hot swapped, such as a hard disk drive or power supply, reseat the component and see if the alarm clears. If the alarm does not clear, replace the component.

    Orange on a component or an orange label on or near a component indicates that the component can be hot-swapped. (Orange can also indicate touch points on hot-swap components.) See the instructions for removing or installing a specific hot-swap component for any additional procedures that you might have to perform before you remove or install the component.

    ImportantImportant

    Do not remove a component with blue touch points while the server is running. Blue touch points indicate that the component cannot be hot swapped.

  4. Check all cables and power cords.
  5. If the LED lights up for a component that cannot be hot swapped or if the sever is already turned off, connect a customer-provided keyboard, mouse, and monitor to the server.
  6. Perform the appropriate shut down procedure for the application that is running on the server.
  7. If the LED was lit for a component that cannot be hot swapped, reseat or replace the component. See the procedure for replacing the component. Replaceable components that cannot be hot swapped are:
    • DIMMs

    • 2-port Ethernet card (PCIe card)

    • RAID battery

  8. Check for successful completion of power-on self-test (POST). POST error messages are displayed on the system monitor.
