parallel to the Processor Baseboard. Slowly depress the levers until the memory
board connector fully engages.
4. Tighten the two captive screws that secure the extraction handle assembly.
5. Place the two board clamps along the sides of the memory board such that the
screws align with their respective holes and secure them.
6. Slide the bracket with the thumbscrew that locks the extraction lever over the
extraction levers and tighten the screw.
7. Replace the DC-DC converters as described in “Memory board DC-DC
converters” on page 190.
8. If you removed any DIMMs replace them as described in “DIMMs”.
9. Replace the Processor/Memory Complex as described in “Processor/memory
complex installation ” on page 179.
Note: A torque wrench is required for this procedure. If available, use torque
driver P/N 16F1661 and Phillips head #2 bit P/N 16F1664.
DIMMs
The DIMMs reside on the memory board in the Processor/Memory complex. To
remove or install the DIMMS, remove the Processor/Memory Complex from the
chassis and follow the DIMM installation order and grouping requirements required
for the DIMMS.
DIMM removal
Complete the following actions to remove a DIMM.
Attention: Use extreme care when removing a DIMM. Too much pressure can
damage the socket. Apply only enough pressure on the plastic ejector levers to
release the DIMM.
