To optimize system performance, install dual in-line memory modules (DIMMs) in the sequence that is shown in the following table.
| Installed microprocessors | DIMM connector population sequence |
|---|---|
| Microprocessor 1 | 3, 6, 8, 2, 5, 7, 1, 4 |
| Microprocessor 2 | 11, 14, 16, 10, 13, 15, 9, 12 |
Note The server for Communication Manager 5.2.1 has only one microprocessor installed.
Note Dual microprocessors require equal distribution of DIMMs between the processors. For example, a 12GB DIMM would have connectors 3,6,8 and 11,14,16 populated.
Note If you install quad-rank DIMMs or a combination of quad-rank DIMMs and dual-rank DIMMs, connectors 1, 4, 9, and 12 must be empty.
The following figure shows the numbering sequence of the DIMMs.
| 1 | DIMMs for microprocessor 2 |
| 2 | DIMMs for microprocessor 1 |
| 3 | Back of server |
| 4 | Front of server |
