Bstwrpl; Bus1 - IBM iSeries Series Hardware Problem Analysis And Isolation

BSTWRPL

For use by authorized service providers.
BSTWRPL: Base I/O tower PCI board.
The failing component is the tower card in the FC 9074 Base I/O Tower for Models 830/SB2, an FC 9079
Base I/O Tower for Models 840/SB3, or an FC 9094 Base I/O Tower for a Model 870 or 890.
Identify the system model you are working on and exchange the tower card with the information in the
table below:
System model
Models 830 and SB2
Models 840 and SB3
Models 870 and 890
This ends the procedure.

BUS1

For use by authorized service providers.
The failing item is any card, cable or card enclosure connected to bus 1 that might cause an interface
failure between the service processor and the system unit processor.
The system unit or the base I/O tower has failed and the diagnostic software was not able to isolate the
failure to a single FRU.
1. Check the last IPL status code in SRC data word 3 in the second half of control panel function 12.
12
xxxxxxxxxxxxSSSS
xxxxxxxxxxxxxxxx
2. Choose from the following options:
v If this value is 2000 through 2009 then use the "IPLINTF" on page 350 symbolic FRU instead of
following this procedure.
v If this value is 200A through 2018, then continue with the next step.
3. Attempt a SLOW OVERRIDE IPL to run full processor hardware diagnostics.
a. Power off the system from the control panel.
b. Change the IPL mode to manual, and the IPL speed to SLOW OVERRIDE (S) using control panel
function 2.
c. Power on the system.
Does the same SRC occur?
v Yes: Continue with the next step.
v No: Go to "Starting point for all problems" on page 2 and follow the service actions for the new
SRC.
This ends the procedure.
4. Choose from the following options:
