Power Pip11 - IBM iSeries Series Hardware Problem Analysis And Isolation

v No: Repeat step 14 (See page 174).
v Yes: Reinstall all the parts and go to "Analyze power problems" on page 31.
This ends the procedure.
16. Perform the following:
a. Power off the system.
b. Disconnect one of the disk units in the frame you are working on: FC 7104, or FC 7116 system
unit expansion (DB2, DB3), FC 5075 (DB1), or FC 5095 I/O tower (DB1, DB2).
c. Power on the system.
Does a power reference code occur?
v Yes: Continue with the next step.
v No: Exchange the last disk unit you disconnected in this step (see Remove and replace
procedures).
This ends the procedure.
17. Have you disconnected all the disk units?
v No: Repeat step 16 (See page 175).
v Yes: Replace the following FRUs, see Locations and addresses for the model you are working on.
– Backplane CB1 (FC 5075, 5095)
– Power supply P01
– Power supply P02
This ends the procedure.
Power PIP11: For use by authorized service providers.
You are here because of a power-on problem on a dual line cord system. To correct the problem, perform
this procedure until you can power on the system. The following steps are for the system unit, unless other
instructions are given. Read the "Power PIPs" on page 152 for important safety information before
servicing the system.

1. If an uninterruptible power supply is installed, verify that it is powered on before proceeding.
2. Is the SRC 1xxx-00AC, 1500, 1510, 1520 or 1530?
Yes: Continue with the next step.
v
No: Go to "Starting point for all problems" on page 2.
v
This ends the procedure.
3. Are all the frames and units powered on?
