13. See Locations — Models 830 for the locations and remove and replace procedures. Replace the
following FRUs in order one at a time until the problem is resolved. Be sure to IPL in SLOW
OVERRIDE mode after each replacement.
a. Network Interface Controller card in location M06 in the 830 system unit.
b. Clock card in location M06A in the 830 system unit.
c. Processor regulator card in location M01 in the 830 system unit.
d. Processor card in location M03 in the 830 system unit.
e. Processor card in location M04 in the 830 system unit.
f. System unit backplane in location MB1 in the 830 system unit.
This
ends the procedure.

This is a Model 840, SB3 system unit and FC 9079 base I/O tower. See Locations — Models 840,
SB3 system unit with processor tower and FC 9079 base I/O tower. Replace the following FRUs in
order one at a time until the problem is resolved. See the Remove and replace procedures. Be sure
to IPL in SLOW OVERRIDE mode after each replacement.
a. Network Interface Controller (NIC) card in location M17 in the 840 system unit.
b. Clock card in location M19 in the 840 system unit.
c. Processor regulator card in location M04 in the 840 system unit.
d. Processor regulator card in location M07 in the 840 system unit.
e. Processor card 0 in location M05 in the 840 system unit.
f. Processor card 1 in location M18 in the 840 system unit.
g. Processor card 2 in location M06 in the 840 system unit.
h. Processor card 3 in location M16 in the 840 system unit.
i. System unit backplane in location MB1 in the 840 system unit.
This ends the procedure.
15.
This is a Model 870 or 890 with an FC 9094 Base I/O Tower. See Locations — Models 870 and 890
with an FC 9094 Base I/O Tower. Replace the following FRUs in order one at a time until the problem
is resolved. Be sure to IPL in SLOW OVERRIDE mode after each replacement.
a. HSL I/O bridge card in position C10 in the FC 9094 base I/O tower.
b. Network interface controller (NIC) card in position M41 in the Model 870 or 890 processor tower.
c. Replace each memory card one at a time in the Model 870 or 890 processor tower.
d. Replace HSL cable C0 on the NIC card in position M41 in the Model 870 or 890 processor tower.
This ends the procedure.
BUSCBL1, BUSCBL2, BUSCBL3, or BUSCBLx
For use by authorized service providers.
BUSCBL1, BUSCBL2, BUSCBL3, or BUSCBLx: HSL Loop cable, the HSL loop connections (external or
embedded) or an HSL interposer card in an HSL loop.
The failing component is an HSL cable, the HSL connections (external, internal, or embedded), an internal
HSL ribbon cable, an HSL link embedded in a FRU, or an HSL interposer card in an HSL loop.
Warning: If an HSL cable is pulled, it may result in the HSL connection being lost to frames that were in a
loop after the cable is reconnected. To fix this, you will need to cycle power on the frame with the locked
HSL connection. If this occurs, follow the Power down, power on instructions (See page 294) instructions
below to power down the frames, reconnect the HSL cable, and power the frames back on.
The name of the symbolic FRU given in the Service Action Log (SAL) gives information about the type of
connection at the failing port. Use information about the connection on each end of the cable to determine
the cable type.
v BUSCBL1 indicates the connection is an optical connection.
