Operator information panel

The following illustration shows the controls and LEDs on the operator information panel.

  • Power-on LED:

    When this LED is lit and not flashing, it indicates that the server is turned on. The states of the power-on LED are as follows:

    • Off:

      Power is not present or the power supply, or the LED itself has failed.

    • Flashing rapidly (4 times per second):

      The server is turned off and is not ready to be turned on. The power-control button is disabled. This will last approximately 5 to 10 seconds.

    • Flashing slowly (once per second):

      The server is turned off and is ready to be turned on. You can press the power-control button to turn on the server.

    • Lit:

      The server is turned on.

  • Ethernet activity LEDs:

    When any of these LEDs is flashing, they indicate that the server is transmitting to or receiving signals from the Ethernet LAN that is connected to the Ethernet port that corresponds to that LED.

  • System-locator LED:

    Use this blue LED to visually locate the server among other servers. You can use IBM Systems Director to light this LED remotely. This LED is controlled by the IMM2. When you light the system-locator LED, the LED will blink and it will continue to blink until you turn it off.

  • Check log LED:

    When this yellow LED is lit, it indicates that there are errors that require further diagnosis. Check the IMM2 event log for additional information. See Event logs for more information about event logs.

  • System-error LED:

    When this yellow LED is lit, it indicates that a system error has occurred. An LED on the light path diagnostics panel is lit to help isolate the error. This LED is controlled by the IMM2.

The following table describes the LEDs on the operator information panel and suggested actions to correct the detected problems.

Table 1. Operator information panel LEDs.

Three column table for documenting the LED, description, and action.

LEDDescriptionAction

System locator (blue)

Use this LED to visually locate the server among other servers. You can use IBM Systems Director or IMM2 to light this LED remotely.

 

Check log (yellow)

An error has occurred and cannot be isolated without performing certain procedures.

  1. Check the IMM2 system event log and the system-error log for information about the error.
  2. Save the log if necessary and clear the log afterwards.

System-error (yellow)

An error has occurred.

  1. Check the light path diagnostics LEDs and follow the instructions.
  2. Check the IMM2 system event log and the system-error log for information about the error.
  3. Save the log if necessary and clear the log afterwards.
