v
For model 830 systems the IOP is in card location C01 of the FC 9074 Base
I/O tower in frame 1 of the system unit. To see where the IOP is located in
the system unit locate card position C01 in the Table 41 on page 710
diagram. To determine the CCIN and removal and installation procedure
for the IOP locate card position C01 in the Table 41 on page 710 table.
v
For model 840 systems, the IOP is in card location C01 of the FC 9079 Base
I/O tower in frame 1 of the system unit towers. To see where the IOP is
located in the base I/O tower, locate card position C01 in the Table 42 on
page 720. To determine the CCIN and removal and installation procedure
for the IOP locate card position C01 in the Table 42 on page 720.

Power on the system.
This ends the procedure.
BUS PIP HSL-01
BUS PIP HSL-01, high-speed link - Failure Isolation.
This procedure isolates a failure in an HSL loop. In this procedure you are directed
to examine the loop using HSM.
1. Work with the customer to end all subsystems in all of the partitions using
each partition’s console.
2. From the Primary partition, IPL the system to DST. Do NOT use function 21!
Attention: This procedure MUST be performed from the Primary partition!
3. Get the loop number from the SRC if you do not already have it. The loop
number is in word 7 of the SRC in hexadecimal format.
If you are working from the Service Action Log (SAL) it may be displayed in
the FRU description area in decimal.
If you are working with the SRC in the PAL then the loop number is the
leftmost 4 characters of the DSA in word 7 (BBBB). Use Table 7 on page 281 to
convert the hexadecimal loop number to decimal before continuing with this
procedure.
Check to see if all I/O towers and system units attached to the loop are
powered on.
4. Are all towers and systems on the loop powered on?
No Yes
↓
Go to step 9 on page 290 of this procedure.
5. Are all the powered off towers and systems able to be powered on at this
time?
No Yes
↓
Go to step 7 on page 290 of this procedure.
6. Correct all problems on I/O towers and system units that are preventing them
from powering on.
If that is not possible at this time, then the customer may choose to
re-configure the HSL loop without the I/O towers and system units that
cannot be powered on. Re-configuring the loop by removing those towers and
systems from the loop will allow the loop to be complete.
The customer may also choose to keep those I/O towers and systems in the
loop however, the loop will not be complete until all links in the loop are
functioning.
