Removing and Installing Memory Boards

Two Memory Boards reside in the Processor/Memory Complex: one is on top of the complex and the
other underneath. You can remove or install these memory boards.

Removing Memory Boards

Two memory boards exist, one plugged in to each side of the processor board (the top and the
underside of the Processor/Memory Complex). The following procedure describes the removal
process for either memory board. To remove the memory board, complete the following procedure:
1. Open and remove the Processor/Memory Complex.
2. If desired, remove the DIMMs from the memory board you are removing as described in
"Removing DIMMs" in Chapter 5.
3. Remove the DC-DC converters from the memory board as described in "Removing the
Memory Board DC-DC Converters" in Chapter 5.
4. Loosen the two captive screws holding the sides of the memory board to the processor board.
Each of these screws secures a board clamp that runs along the length of the memory board.
5. Lift the board clamps out of the Processor/Memory Complex.
6. Loosen the two captive screws at the end of the handle that spans the middle of the Memory
Board.
7. Remove the bracket with the thumbscrew that locks the extraction levers.
8. Pull up on the extraction levers to disengage the memory board from the processor board.
NOTE
Figure 5-3. Memory Board DC-DC Converters
Both extraction levers must be raised evenly while disengaging the memory from
the Processor Baseboard. The memory board must remain parallel to the Processor
Baseboard during extraction.
