Replacing a Fan Module

Fan modules are replaceable components that do not require you to power off the server before servicing.

Fan modules are located in the front of the server.

Note:

If the system detects a fan module fault, the front and back panel Fault-Service Required LEDs are lit, as is the front Top Fan LED.

Caution:

When removing and replacing a fan module in the Oracle Server X10, you must complete the entire procedure within 60 seconds to maintain adequate cooling in the system. Remove and replace only one fan module at a time. Ensure that you have obtained the replacement fan module and that it is ready for installation before starting the replacement procedure.

Each fan module contains one fan, with two fan motors per fan. The two fan motors provide separate tachometer signals so that the fan module reports two tach signals to Oracle ILOM. Even if only one fan motor is faulted within the fan module, the Oracle ILOM service processor detects that two fan motors have failed to spin while the fan module is removed. If the fan module is not replaced within 60 seconds of removal, Oracle ILOM will take the protective action to shut down the system to prevent thermal damage to the system.

If the cover is not installed within 60 seconds, the system may shutdown due to over-temperature or a PCIe card may overheat, potentially damaging it.

Remove a Fan Module

You do not have to power off the server to replace fan modules.

  1. Extend the server to the maintenance position.

    See Extend the Server to the Maintenance Position.

  2. To access the fan modules, remove the server top cover.

    See Remove the Server Top Cover.

  3. Identify the faulty fan module.

    Each fan module has a fan service action required status indicator (LED) that is located next to the module. If the LED is amber, the fan has failed. The location of the fan status LED is shown in the following figure.

    Figure showing the location of fan modules and associated status indicators.

  4. Using your forefinger and thumb, lift the fan module straight up and out of the chassis and set it aside on an antistatic mat.

    Figure showing how to remove a fan module.

Install a Fan Module

  1. Remove the replacement fan module from its packaging, and place it on an antistatic mat.

  2. With the server top cover removed, install the replacement fan module into the server.

    The fan modules are keyed to ensure that they are installed in the correct orientation.

    Figure showing how to install a fan module.

  3. Press down on the fan module to fully seat the fan module.

  4. Verify that the fan module status indicator (LED) for the replacement fan module is not illuminated.

  5. Install the server top cover.

    See Install the Server Top Cover.

  6. Verify that the Top Fan Fault LED on the front of the server and the Fault-Service Required LEDs on the front and back of the server are not illuminated.

  7. Return the server to operation.

    See Returning the Server to Operation.
