Twrplnr - IBM iSeries Series Hardware Problem Analysis And Isolation

v For FC 5088 or FC 0588, choose from the following options:
– (With reference code 7610, 7611, 7620, 7621, 7630, 7631, 7640, 7641) replace one part at a
time:
- Air moving device (AMD) control card (see Locations - FC 5078, 0578 Expansion I/O unit for
locations and part number information)
- part CCIN 28B8 (TWRCARD)
– (Except reference code 7610, 7611, 7620, 7621, 7630, 7631, 7640, 7641) replace - part CCIN
28B8 (TWRCARD).

v For xSeries Server Tower, replace the Integrated xSeries
Integrated xSeries
the remove and replace procedures before exchanging the part.
Note: For SRC 1xxx-8910 or 8920, ac removal is required to reset the flashing (frame indicating)
LEDs that are located on the TWRCARD.
This ends the procedure.

TWRPLNR

TWRPLNR: I/O tower PCI board.
The failing component is in the Tower Card of an FC 5074, FC 5079 (1.8m) Expansion I/O Tower, or an
FC 5078/0578 Expansion I/O Unit, or (on a Model 830, 840, SB2, SB3, or 890) a FC 9074, FC 9079, or
FC 9094 Base I/O Expansion Tower.
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
component, 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 tower contains the failing component. Record the
tower type.
2. Use the feature code of the tower or expansion unit and the table below to determine the service
information for the failing component.
