v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v See Chapter 3, "Parts listing, Type 8406," on page 229 to determine which components are CRUs and which
components are FRUs.
v If an action step is preceded by "(Trained service technician only)," that step must be performed only by a
trained service technician.

Action
Replace the CRU called out after this FSPSP call. If the CRU that is
called out is a DIMM CRU, perform the following procedure:
1. Replace both memory DIMMs of the pair on the microprocessor that
contains the failing CRU:
DIMM 1 (Px-C1)
For P1-C1, replace DIMMs 1 and 3; for P2-C1, replace
DIMMs 9 and 11.
DIMM 2 (Px-C2)
Replace DIMMs 2 and 4, or DIMMs 10 and 12.
DIMM 3 (Px-C3)
Replace DIMMs 1 and 3, or DIMMs 9 and 11.
DIMM 4 (Px-C4)
Replace DIMMs 2 and 4, or DIMMs 10 and 12.
DIMM 5 (Px-C5)
Replace DIMMs 5 and 7, or DIMMs 13 and 15.
DIMM 6 (Px-C6)
Replace DIMMs 6 and 8, or DIMMs 14 and 16.
DIMM 7 (Px-C7)
Replace DIMMs 5 and 7, or DIMMs 13 and 15.
DIMM 8 (Px-C8)
Replace DIMMs 6 and 8, or DIMMs 14 and 16.
2. See "Removing a memory module" on page 244 for location
information and the removal procedure.
3. Install new memory DIMMs, as described in "Installing a memory
module" on page 245.
See "Supported DIMMs" on page 4 for more information.
Replace the system board and chassis assembly, as described in
"Replacing the FRU system-board and chassis assembly" on page 260.
