Avoid over torquing the MPA captive screws when installing the MPA. Tighten the captive screws on the
MPA to a torque of 6 +/-0.5 inch-pound.
Note
4. To remove the MPA from the chassis, use a number 2 Phillips screwdriver to loosen the captive screws
on the MPA. Ensure that you first loosen the right screw and then the left.
5. Grasp the MPA and pull the MPA from the chassis. (You have already disconnected the cables from the
MPA.)
