5. Remove the side shield from the defective module.

a. Using a Philips #1 (PH1) screwdriver, remove the two screws that secure the side shield to the

module.

NOTE: Keep the screws

; extra screws are not included with the replacement module.

b. Slide the shield toward the module's front panel. This aligns the engagement tabs so you can remove

the shield.
