CEC enclosure memory DIMM location codes

Figure 4. Memory module locations on the processor card (Un-P2-Cx) (Models 941, 951)
CEC memory DIMM card locations
Memory module location is P2-Cx-Cy where:

x = System processor card slot 1 or slot 2
y = Memory DIMM slot 1 thru 12 as shown

Notes:
  1. First quad of memory modules is plugged into memory module slots P2-Cx-C3, P2-Cx-C6, P2-Cx-C9, and P2-Cx-C12.
  2. Second quad of memory modules is plugged into memory module slots P2-Cx-C2, P2-Cx-C5, P2-Cx-C8, and P2-Cx-C11.
  3. Third quad of memory modules is plugged into memory module slots P2-Cx-C1, P2-Cx-C4, P2-Cx-C7, and P2-Cx-C10.
