Installing Fans
Fan speed is controlled by system temperature via 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).
1. With the server powered on, remove the chassis cover and inspect the fans to see
which one has failed.
2. Power down the server as described in Section 3.1.
3. Remove the failed fan's wiring from the fan header on the motherboard.
4. Lift the failed fan from the chassis and pull it completely out.
5. Place the new fan into the vacant space in the housing while making sure the arrows on
the top of the fan (indicating air direction) point in the same direction as the arrows on
the other fans.
6.
7. Power up the system and check that the fan is working properly before replacing the
chassis cover.
