PPCITWR
For use by authorized service providers.
PPCITWR: Primary PCI bus in an I/O tower.
There are potentially two failing components. The HSL I/O bridge card and the tower card in an FC 5074,
FC 5088, FC 0588, FC 5095, FC 0595, the base I/O tower for Models 870 or 890, or the FC 5078, FC
0578 Expansion I/O Unit.
1. If you are using the Service Action Log (SAL) and there is a frame ID given for this FRU, then that is
the frame with the failing component or components. Continue with the next step of this procedure.
Otherwise, determine the location of the frame by using the DSA in the SRC. Record the bus number
value, BBBB, in word 7 of the SRC, see “Breaking down the SRC” on page 63 for help in determining
the bus number. Search for the bus number in HSM or the System Configuration Listing to determine
which tower contains the failing component. Record the tower type.
2. Exchange symbolic FRU “SIADPCD” on page 446, and return here.
3. If the problem still exists after powering on the tower, then exchange symbolic FRU “TWRPLNR” on
page 473.
This ends the procedure.

PRI_PCI
For use by authorized service providers.
PRI_PCI: Primary PCI bus.
This is a PCI bus generated under an HSL I/O bridge.
1. Choose from the following options:
v If you are working from the Service Action Log and a card position is listed with this failing item,
then that is where the error is located. Continue with the next step in this procedure.
v Otherwise, record the bus number value, BBBB, in word 7 of the SRC (see “Breaking down the
SRC” on page 63 for help in determining the bus number). Search for the bus number in HSM or
the System Configuration Listing to determine which frame or I/O tower contains the failing item.
Record the frame or tower type.
2. Use the following table to determine which symbolic FRU or FRUs to go to for PRI_PCI.
