Caution A fan tray weighs approximately 19.15 pounds (8.69 kg). Use both hands when handling a fan tray.
Step 6 Slide the fan tray into the bay.
Step 7 Slide the fan tray into the fan tray bay. Stop when the fan tray meets the chassis connector in the back of the fan tray bay.
Notice that the tray (and rail guides) drop just inside the fan tray bay door, so that the fan tray “drops” into its final position as it gets almost all the way into the chassis.
Caution To prevent damage to the chassis connector, do not use excessive force when inserting a fan tray into its bay.
Step 8 Firmly push on the fan tray to seat the fan tray connector in the chassis connector.
Note All electrical and control line connections are made automatically when the connectors mate.
Step 9 Rotate the fan tray handle to the closed (flush) position.
Step 10 Replace the fan tray bay door and tighten the two captive screws on the fan tray bay door.
