The DIMM number and bank number are repeated in the same order for each CPU
processor. DIMM number 3, bank 0 is the first DIMM, and DIMM number 3, bank 1
is the second DIMM in each DIMM bank. The CPU processor number is noted on the
metal cover.
9.3.1 DIMM Bank Configuration Guidelines
Follow these DIMM configuration guidelines:
■
Each DIMM bank must be fully populated with the same capacity DIMM.
■
Install the larger capacity DIMMs into banks before installing the smaller capacity
DIMMs into banks.
■
The minimum number of DIMMs you can install per CPU processor is four
DIMMs for one bank.
■
If the number of CPU processors on each CPU/Memory board is the same, place
DIMM banks on CPU/Memory boards that have fewer populated DIMM banks
before placing DIMMs on CPU/Memory boards that already have more
populated DIMM banks.
■
If some CPU/Memory boards have more CPU processors than others, place
DIMMs in DIMM banks on the board with the most CPU processors. There will
be CPU processors without corresponding DIMMs on other boards.
9.3.2 Removing DIMMs
Caution – The system is sensitive to static electricity. Make sure you are wearing a
grounded wrist strap when handling system components. Always place components
on a grounded ESD mat close to the system
1. Remove the applicable CPU/Memory board.
See Section 9.2.1, “Removing a CPU/Memory Board” on page 9-4 .
2. Place the CPU/Memory board on the ESD mat.
