MAP 154B: Insufficient Hardware Resources Problem IsolationStep 154B-1Record the error code, location code(s) and word 13 that sent you to this MAP.Step 154B-2Turn off the power.Step 154B-3Make sure the power is off on the base system drawer.Step 154B-4Attention: Before replacing any parts examine the base system drawer for violation of any of thefollowing configuration constraints.v Memory DIMMs must be installed in quads and in the correct slots. A quad is a group of four memoryDIMMs.v Quads are populated in DIMM slots 1, 3, 6, 8 first, and then 2, 4, 5, 7. The only two valid slotcombinations 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 systembackplane 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 theprocessor 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 atU0.1-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 atU0.1-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-5Turn on the power.Step 154B-6Did 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.Go to ″MAP 0410: Repair Checkout″ in the RS/6000 Eserver pSeries Diagnostic Information forMultiple Bus Systems.Yes Go to “Step 154B-7.”Step 154B-7Have all the cards listed in “Step 154B-4” been replaced?No Go to “Step 154B-2.”128 EserverpSeries 615 Service Guide
