•
XDIF and RF Amp/RF Amp2
a.) Remove the three screws that fasten the XDIF board to the front of the card rack chassis.
b.) Carefully eject and partially remove the XDIF and RF Amp boards simultaneously. Remove
the boards just enough in order to grab both sides of the Top Plane board.
c.) Hold the XDIF and RF Amp boards. Carefully grab each SIDE of the Top Plane Board. Gently
rock the Top Plane board side to side while pulling it off of its connectors.
NOTE:
Rocking the Top Plane board top to bottom will afford a greater opportunity to bend pins during
its extraction. Only rock the board side-to-side while removing it.
d.) Once the Top Plane Board is removed, either the XDIF or RF Amp can be removed from the
card rack.
