Add the new SAS expansion card

You install the SAS expansion card to allow for drive tray expansion.

Before you begin


  1. Remove the controller canister's cover by unscrewing the single thumbscrew and lifting the lid open.
  2. Confirm that the green LED inside the controller is off.
    If this green LED is on, the controller is still using battery power. You must wait for this LED to go off before removing any components.
  3. Using a #1 Phillips screwdriver, remove the two screws that attach the faceplate to the controller canister, and remove the faceplate.
  4. Align the single thumbscrew on the SAS expansion card with the corresponding hole on the controller, and align the connector on the bottom of the expansion card with the expansion card interface connector on the controller card.
    Be careful not to scratch or bump the components on the bottom of the SAS expansion card or on the top of the controller card.
  5. Carefully lower the SAS expansion card into place, and seat the expansion card connector by pressing gently on the expansion card.
  6. Hand-tighten the SAS expansion card thumbscrew.
    Do not use a screwdriver, or you might over tighten the screws.
  7. Using a #1 Phillips screwdriver, attach the faceplate you removed from the original controller canister to the new controller canister with the two screws.
