Removing the PERC H345 front card

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.
  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.
    1. Systems with an H345 front controller in the upside-down orientation will need to have both the backplane and controller removed at the same time due to the small amount of clearance available. To do so, uninstall all drives from the backplane, disconnect all cables to the PERC and backplane, and then lift the backplane and PERC out of the system carefully.
  5. Disconnect any SAS cables connected to the card:
    1. Press down and hold the metal tab on the SAS cable connector.
    2. Pull the SAS 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 SAS cable before reconnecting it to the backplane.
    1. For systems configured with a H345 front controller in an 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 H345 front controllers.
  9. Close the system.
  10. Reconnect the system to its electrical outlet and turn the system on, including any attached peripherals.
