1. Install the DRAM SIMM, Flash Memory, and Security PAL on the
controller board (page 224).
2. Position the controller board assembly in the card cage, shield side

cage in the keyway in the controller shield. Slide the board to right until
the serial cable connector J201 on the board lines up with the cutout in
the card cage. (See page 275, Figure 45.)
