IBM iSeries 820 Hardware Problem Analysis And Isolation

Is SRC 1xxx 6400 or 6401 displayed?
v Yes: If there are some regulators that you have not yet tried replacing, then repeat step 12 (See
page 414). However, if you have tried exchanging all of the regulators, continue with the next
step.
v No: The regulator that was removed in this step is the failing item.
This
ends the procedure.
13.
Perform the following:
a. Power off the system.
b. Remove the new regulator that you just installed, and replace it with the original regulator.
c. Remove all the cards in the expansion bus.
CAUTION:
To prevent overheating problems, do not remove any device completely from the enclosure
unless you install an airflow card in its place.
d. Power on the system.
Is SRC 1xxx 6400 or 6401 displayed?
v No: Continue with the next step.
v Yes: Exchange the backplane in the expansion. See symbolic FRU “BACKPLN” on page 284.
This ends the procedure.
14.
Perform the following:
a. Power off the system.
b. Reinstall one of the cards you removed from the expansion bus in step 13 (See page 415).
c. Power on the system.
Is
the SRC 1xxx 6400 or 6401 displayed?
v No: Repeat step 14 (See page 415) until all the cards have been reinstalled.
This ends the procedure.
v Yes: Power off the system. Replace the last card installed in this step.
This
ends the procedure.
PIOCARD
For use by authorized service providers.
PIOCARD: PCI I/O card, IOP, or IOA.
The multi-adapter bridge hardware detected an error in an adapter card, IOP, or IOA. The failing
component is the card installed in the card location specified by the Direct Select Address (DSA).
1. If you are using the Service Action Log (SAL) and there is a card position given for this FRU, then that
is the location of the failing component. Go to step 3 (See page 416). Otherwise, perform the following:
v Determine the location of the card using the DSA in the SRC. Record the Direct Select Address
(DSA), which is word 7 of the SRC from the SAL display.
v Locate the card specified in the DSA by going to “Bus PIP PCIBUS-PIP1” on page 99. Return here
after locating the card.
v If you are working on a system Model 270 or 820, go to step 3 (See page 416). For all other system
models, continue with the next step.
2.
Did “Bus PIP PCIBUS-PIP1” on page 99 identify a single card position?
v Yes: This is the location of the failing item. Continue with the next step.
v No: While referring to the remove and replace procedures for each card position, perform the
following: (You can find links to the locations information, and from there to the remove and replace
procedures, in the table at the end of this procedure.)
a. Remove all of the cards in the card positions that are identified in the given range of card slots.
