Steps

1. Turn off the system, including any attached peripherals, and disconnect the system from the electrical outlet and

peripherals.

2. Open the system.

3. Locate the PERC card in the controller carrier at the front of the system.

CAUTION: To prevent damage to the card, you must hold the card by its edges only.

4. Unscrew the fasteners on the controller carrier, and slide the carrier away from the backplane to disconnect the controller

from the backplane.

If you are removing a PERC H755N front NVMe controller in the upside down orientation, you must remove both the

backplane and the controller at the same time because of the limited clearance available:

a. Uninstall all drives from the backplane.

b. Disconnect all cables between the PERC and the backplane.

c. Lift the backplane and PERC from the system.

5. Disconnect any cables connected to the card:

a. Press down and hold the metal tab on the cable connector.

b. Pull the cable out of the connector.

6. Remove the PERC controller from the controller carrier.

7. Insert the replacement controller into the carrier and secure it with the appropriate screws.

8. Take the replacement storage controller and reconnect the cable before reconnecting it to the backplane.

If you are removing a PERC H755 front NVMe controller in the upside down orientation, reattach the PERC controller to the

backplane first before reinstalling the backplane into the system. For more information on installing the card, see Installing

the PERC H755N front NVMe card.

9. Close the system.

10. Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.
