4. Push the FB-DIMM into the connector until the ejector tabs lock the FB-DIMM
in place.
If the FB-DIMM does not easily seat into the connector, verify that the orientation
of the FB-DIMM is correct. If the orientation is reversed, damage to the FB-DIMM
might occur.
5. Repeat Step 2 through Step 4 until all the FB-DIMMs are installed.

Supported FB-DIMM Configurations
Use these FB-DIMM configuration rules to help you plan the memory configuration
of your server:
■ Each CMP/memory module pair holds 16 industry-standard FB-DIMMs.
■ 4 FB-DIMM slots are located on the CMP module
■ 12 FB-DIMM slots are located on the memory module.
■ All FB-DIMMs in the system must be the same density (same capacity).
■ At minimum, Channel 0, FB-DIMM Slot 0 in all branches must be populated.
■ In branches populated with more than one FB-DIMM (for example, in 8 and 16
FB-DIMM configurations), FB-DIMMs are addressed in pairs. Each pair must be
identical (same part number).
■ A replacement FB-DIMM must have the same part number as the other FB-DIMM
in its pair. For example, a replacement FB-DIMM in J1201 must have the same part
number as the FB-DIMM in J1401, in order to ensure an identical pair.
■ If you are unable to obtain a matching FB-DIMM, you must replace both
FB-DIMMs in the pair.
Each CMP/memory module pair supports the following configurations:
■ 4 FB-DIMMs (Group 1)
■ 8 FB-DIMMs (Groups 1 and 2)
■ 16 FB-DIMMs (Groups 1, 2, and 3) (fully populated configuration)
