INSTALLING THE HARDWARE REMOVING A MEMORY MODULE
2-46
Note:
The memory population is coded in one yellow
memory slot and one black memory slot for each channel
(Two DIMMs per channel). You should install the memory modules to all the available yellow DIMM slots
first, then the black DIMM slots for each processor for better performance.
Removing a Memory Module
1. Remove the mainboard sled. See Removing a Mainboard Sled on page 2-11.
