MAP 154B: Insufficient Hardware Resources Problem Isolation
Step 154B-1
Record the error code, location code(s) and word 13 that sent you to this MAP.
Step 154B-2
Turn off the power.
Step 154B-3
Make sure the power is off on the base system drawer.
Step 154B-4
Attention: Before replacing any parts examine the base system drawer for violation of any of the
following configuration constraints.
v Memory DIMMs must be installed in quads and in the correct slots. A quad is a group of four memory
DIMMs.
v
Quads are populated in DIMM slots 1, 3, 6, 8 first, and then 2, 4, 5, 7. The only two valid slot
combinations that you can use are 1, 3, 6, and 8 OR 2, 4, 5, and 7.
v At least one quad of DIMMs must be installed on the system backplane: U0.1-P1-My, where y is 1, 3, 6,
and 8. See the illustration in “Memory DIMM Locations” on page 17.
v
Each memory DIMM in a quad must be the same type and size. However, both quads on the system
backplane are not required to be the same.
Replace the following cards, if present, one at a time:
v First location code item recorded, if any, in “Step 154B-1.”
v Second location code item recorded, if any, in “Step 154B-1.”
v Third location code item recorded, if any, in “Step 154B-1.”
v Replace the service processor card at U0.1-P1-X1, if not recorded in “Step 154B-1.”
v
If the value of word 13, recorded in “Step 154B-1,” is 402F0000, 403F0000, or 40FF0000, replace the
processor backplane at U0.1-P1, if not recorded in“Step 154B-1.”
v If the value of word 13, recorded in “Step 154B-1,” is 40600000, replace the system backplane at
U0.1-P1, if not recorded in “Step 154B-1.”
v
If the value of word 13, recorded in “Step 154B-1,” is 41100000, replace the system backplane at
U0.1-P1, if not recorded in “Step 154B-1.”
v Memory DIMMs at locations U0.1-P1-M1, M3, M6, M8, if not recorded in “Step 154B-1.”
v Memory DIMMs at locations U0.1-P1-M2, M4, M5, M7, if not recorded in “Step 154B-1.”
v System backplane at U0.1-P1, if not recorded in “Step 154B-1” and if not already replaced.
Step 154B-5
Turn on the power.
Step 154B-6
Did the system stop with the same error code as recorded in “Step 154B-1”?
No The card just replaced was defective. This ends the procedure.
