4) After installing the new board power the unit on to be sure that the
system initializes.
(Note: All the LED’s on the Power Supply board should be lit up when
the system is initialized.) If they are not it is possible that a pin has gotten
bent during the installation. Shut the unit off and pull the board out, check
the pins and try re-inserting the board again.
5) It is important to push firmly to be sure the board is completely seated
into both connectors on the Interconnect board.
6) Once all the lights are lit on the Power Supply board you will need to re-
install the stabilization bracket and the two screws.
7) There is a slot on the stabilization bracket. Be sure that the edge of the
board fits tightly in this slot. Figure 5
