Prerequisites
CAUTION:
Many repairs may only be done by a certified service technician. You should only perform
troubleshooting and simple repairs as authorized in your product documentation, or as directed by the online or
telephone service and support team. Damage due to servicing that is not authorized by Dell is not covered by
your warranty. Read and follow the safety instructions that are shipped with your product.
NOTE: It is recommended that you always use a static mat and static strap while working on components in the interior of
the system.
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, disconnecting the controller
from the backplane.
If you are removing a PERC H755 front SAS 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 cables 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.
