Replace Fans

Six hot-swap, heavy-duty rear mounted fans provide cooling. They can be replaced without powering down the system.

Fan speed is controlled by a system temperature setting in IPMI. If a fan fails, the remaining fans will ramp up to full speed. Replace any failed fan at your earliest convenience with the same type and model. The system can continue to run with a failed fan and all six fans will operate as long as one node is powered on.

  1. While the power is running, examine the fans to determine which fan has failed.

  2. On the failed fan, simultaneously squeeze the fan's side release tabs inward.

  3. Pull the fan out of the motherboard sled using the tabs.

    Caution: Fans will continue to rotate for a brief time after removing them from the chassis. To avoid injury, keep fingers clear of the rotating fan blades.

  4. Place the new fan into the vacant fan bay and confirm that the fan is fully seated in the fan bay.

  5. Make sure the new fan is functioning properly.

  • Review the following to ensure the server has proper airflow.

  • Make sure there are no objects to obstruct airflow in and out of the server.

  • If you are using a front bezel, make sure the bezel filter is replaced periodically.

  • Do not operate the server without drives or drive trays in the drive bays.

  • Use only recommended server parts.

  • Make sure no wires or foreign objects obstruct air flow through the chassis. Pull all excess cabling out of the airflow path or use shorter cables.

  • The control panel LEDs display system heat status.

Important Information: Overheating

If the enclosure overheats:

  1. Use the LEDs to determine the nature of the overheating condition.

  2. Confirm that the chassis covers are installed properly.

  3. Make sure all fans are present and operating normally.

  4. Check the routing of the cables.
