Storage Device I/O Processor (Sdiop) Pips - IBM iSeries Series Hardware Problem Analysis And Isolation

Is the ac voltage form 200 V ac to 240 V ac? On a FC 5095 the ac voltage may also be 100 V to
127 V ac.
No: Continue with the next step.
v
v Yes: Go to step 14 (See page 185).
13. Perform the following:
a. Disconnect the ac line cord from the customer's ac power outlet.
b. Use a multimeter to measure the ac voltage at the customer's ac power outlet.
Is the ac voltage from 200 V ac to 240 V ac? On a FC 5095 the ac voltage may also be 100 V to 127
V ac.
v Yes: Exchange the failing ac line cord.
v No: Perform the following:
a. Inform the customer that the ac voltage at the power outlet is not correct.
b. Reconnect the ac line cords to the power outlet after the ac voltage at the power outlet is
correct.
This ends the procedure.
14. Perform the following:
a. Reconnect the ac line cords to the AC module.
b. Disconnect the ac power jumper cables from the AC module output.
c. Use a multimeter to measure the ac voltage at the AC module outlets to the power supplies.
Is the ac voltage from 200 V ac to 240 V ac? On a FC 5095 the ac voltage may also be 100 V to
127 V ac.
v No: Exchange the AC module:
– FC 5074, FC 5079, FC 9074, FC 9079 (see Locations and addresses )
– FC 5094 or FC 9094 (see Type, model, and part number list for part number.)
This ends the procedure.
v Yes: Perform the following:
a. Connect the ac power jumper cables to the AC module.
b. Disconnect the ac power jumper cable at the power supplies.
c. Use a multimeter to measure the ac voltage to the power jumper cables input to the power
supplies.
Is the ac voltage from 200 V ac to 240 V ac for each power jumper cable? On a FC 5095 the ac
voltage may also be 100 V to 127 V ac.
– Yes: Exchange the power supply - see symbolic FRU "PWRSPLY" on page 431.
This ends the procedure.
– No: Exchange the power jumper cable.
This ends the procedure.

For use by authorized service providers.
Use these procedures to isolate a failure in the multiple function I/O card.
Read all safety procedures before servicing the system. Observe all safety procedures when performing a
procedure. Unless instructed otherwise, always power off the system or expansion tower where the FRU is
located, (see Power on/off the system and logical partitions) before removing, exchanging, or installing a
field-replaceable unit (FRU).
