DIMM 2 (P1-C2)
Memory module 2
DIMM 3 (P1-C3)
Memory module 3
DIMM 4 (P1-C4)
Memory module 4
DIMM 5 (P1-C5)
Memory module 5
DIMM 6 (P1-C6)
Memory module 6
DIMM 7 (P1-C7)
Memory module 7
DIMM 8 (P1-C8)
Memory module 8
2. See "Removing a memory module" on page 251 for location
information and the removal procedure.
3. Install new memory DIMMs, as described in "Installing a memory
module" on page 251.
See "Supported DIMMs" on page 4 for more information.
1. Collect the error log information.
2. Get the DSA, which is word 7 of the associated B700xxxx SRC.
3. Use the hexadecimal value of the DSA to determine the location code
of the failing CRU.
v If the value is 05120010, the location code is P1-C10.
v If the value is xxxx 0100, the location code is P1-C11.
