the next step of this procedure. Otherwise, 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. To locate the card specified in the
DSA go to “BUS PIP PCIBUS-PIP1” on page 320. Return here after locating the
card and continue with this procedure.
2. Did BUS PIP PCIBUS-PIP1 identify a single card position?
Yes No
↓ Perform the following, while referring to the removal and exchange
procedures for each card position. The removal and exchange
procedures for the card positions are linked to by the instructions
starting at step 3 of this procedure.
a. Remove all of the cards in the card positions that are identified.
b. Replace each card, one at a time, powering on the system or tower
(as instructed in the removal and installation procedure) after you
replace each one, until the problem appears again. The last card that
you replace, when the problem appears again, is the failing item.
This ends the procedure.
3. Refer to FRU Locations and Failing components table for the frame or tower
type where the card is located.
4. The step(s) which follow will help you to determine the removal and
installation procedure for the card position(s) that you identified, by linking
you to the correct ″FRU Locations and Failing Components″ table.
5. Use the system model, tower, expansion unit or machine type that you
determined in step 1 on page 564 of this procedure and the table below to
exchange the FRU with the failing component.
