14 Servicing the Front LED Indicator Module (FRU)

The following section describes how to service the front LED indicator module. The front LED indicator module is a field-replaceable unit (FRU). For more information about FRUs, see Illustrated Parts Breakdown and Field-Replaceable Units.

Caution:

The front LED indicator modules must be removed and replaced only by authorized Oracle Service personnel.

Caution:

Ensure that all power is removed from the server before removing or installing a front LED indicator module. You must disconnect the power cables before performing this procedure.

Caution:

These procedures require that you handle components that are sensitive to electrostatic discharge. This sensitivity can cause the component to fail. To avoid damage, ensure that you follow electrostatic discharge safety measures and antistatic practices. See Electrostatic Discharge Safety.

This section covers the following procedures:

Troubleshooting Using the Server Front and Back Panel Status Indicators

Remove the Front LED Indicator Module

  1. Prepare the server for service.
    1. Power off the server and disconnect the power cords from the power supplies.
    2. Extend the server into the maintenance position.
    3. Attach an antistatic wrist strap to your wrist, and then to a metal area on the chassis.
    4. Remove the server top cover.
  2. Disconnect the LED indicator module cable from the motherboard.

    Note:

    You might need to disconnect the SAS cable connections from the Oracle Storage 12 Gb SAS PCIe RAID HBA, Internal card or the NVMe cable connections from the Oracle Retimer card in PCIe slot 10 to access the LED indicator module motherboard cable connection. To ease removal of the LED indicator module cable, slightly lift the SAS or NVMe cable bundles from the cable trough along the left side of the chassis. See Servicing SAS Cables (FRU) or Servicing NVMe Cables (FRU).

  3. Remove the three No. 2 Phillips screws that secure the FIM cable and Temperature Sensor Access cover to the chassis [1].

    Figure showing the removal of the front LED indicator module.
  4. Lift up and remove the FIM cable and Temperature Sensor Access cover from the FIM cable and Temperature Sensor Access cover slot [1].

    Set aside the FIM cable and Temp Sensor Access cover.

  5. Remove the front LED indicator module [2].
    1. Remove the two No. 2 Phillips screws that secure the LED indicator module to the server front panel.
    2. Remove the LED indicator module and cable from the server front panel.

      Remove the LED indicator module cable by carefully pulling the cable through the cable trough along the left side of the chassis.

Install the Front LED Indicator Module

  1. Install the front LED indicator module.
    1. Push the LED indicator module and cable through the LED housing on the server front panel [1].

      Figure showing the installation of the front LED indicator module.
    2. Install the LED indicator module cable by carefully pulling the cable through the cable trough along the left side of the chassis.

      Note:

      To ease installation of the LED indicator module cable, slightly lift the SAS or NVMe cable bundles from the cable trough along the left side of the chassis.

      Note:

      Cable part number 7315469 is required for the LED indicator module.
    3. Insert and tighten the two No. 2 Phillips screws to secure the LED indicator module to the server front panel [1].
    4. Install the FIM cable and Temperature Sensor Access cover to the chassis by inserting it into the FIM cable and Temperature Sensor Access cover slot [2].

      Caution:

      Be careful not to damage the temperature sensor when installing the FIM cable and Temperature Sensor Access cover to the chassis.
    5. Install the three No. 2 Phillips screws to secure the FIM cable and Temperature Sensor Access cover to the chassis [2].
  2. Reconnect the LED indicator module cable to the motherboard.

    Note:

    You might need to disconnect the SAS cable connections from the Oracle Storage 12 Gb SAS PCIe RAID HBA, Internal card or NVMe cable connections from the Oracle Retimer card in PCIe slot 10 to access the LED indicator module motherboard cable connection. See Servicing SAS Cables (FRU) or Servicing NVMe Cables (FRU).

    Figure showing the LED indicator module cable being reconnected to the motherboard.
  3. Return the server to operation.
    1. Install the server top cover.
    2. Return the server to the normal rack position.
    3. Reconnect the power cords to the power supplies, and power on the server.
    4. Verify that the power supply AC OK LED is lit.
