Instructions for Models 270, 820, 830, 840, SB2, and SB3
1. If the system has logical partitions, perform this procedure only from the Primary partition’s console
and the system control panel. To determine if the system has logical partitions, go to Determine if the
system has logical partitions before continuing with this procedure.
2. With the system powered on, power off the frame that you are working on by removing the line cords
at the FC 5078, FC 0578, FC 5088, and FC 0588 power supplies. See the Expansion unit power
procedure.
3. Remove and label all cards installed in the PCI backplane area.
4. Power on the frame by reconnecting the ac power cables to the unit that you are working on.
Does a power reference code occur?
v Yes: Continue with the next step.
v No: Go to step 11 (See page 170).
5. Is the SRC 1xxx 2603?
v No: Continue with the next step.
v Yes: Replace the PCI backplane. See symbolic FRU “TWRCARD” on page 470.
This
ends the procedure.
6. Perform the following:
a. Power off the frame that you are working on, by removing the line cords at the FC 5078, FC
0578, FC 5088, FC 0588 power supplies.
b. Remove power supply P01.
c. Remove the B01 assembly from the original power supply, and install it on the new power supply.
d. Install the new power supply P01.
e. Power on the frame by reconnecting the ac power cables to the unit that you are working on.
Does a power reference code occur?
v Yes: Continue with the next step.
v No: The Power supply P01 that you removed in this step is the failing item.
This ends the procedure.
7. Perform the following:
a. Power off the frame that you are working on, by removing the line cords at the FC 5078, FC
0578, FC 5088, and FC 0588 power supplies.
b. Remove the new power supply P01 and replace it with the original power supply P01, after
switching the B01 assembly back to the original supply.
c. Remove power supply P02.
d. Remove the B02 assembly from the original power supply P02 and install it on the new power
supply.
e. Install the new power supply P02.
f. Power on the frame by reconnecting the ac power cables to the unit that you are working on.
Does a power reference code occur?
v Yes: Continue with the next step.
v No: The Power supply P02 that you removed in this step is the failing item.
This ends the procedure.
8. Perform the following:
a. Power off the frame that you are working on, by removing the line cords at the FC 5078, FC
