3.Remove the fan tray from the anti-static shielded bag.

4.Holding the fan tray level, guide it into the carrier rails on each side and gently push it all the way into the slot, ensuring that it firmly engages with the connector.

5.When you are sure the fan tray has properly engaged the connector, tighten the retainer screws to secure the fan tray in the slot.
