Does the same SRC occur?
v Yes: Continue with the next step.
v No: If the system IPLs past the original error, then isolate to the failing IOP or IOA card. Follow the
service actions for the new SRC.
This ends the procedure.
12. Remove and label all of the storage device units EXCEPT for the alternate IPL load-source device
unit you are currently using. (This includes all of the disk devices in D01 - D12.)
If the system IPLs past the original error, then isolate to the failing device unit.
If the failure still occurs, replace the following FRUs one at a time until the problem is resolved. See
the Remove and replace procedures.
v First storage IOA
v System unit backplane in location MB1
13. For Models 830, 840, SB2, or SB3: Is this system a Model 830 with SB2 system unit and FC 9074?
v Yes: Continue with the next step.
v No: Go to step 16 (See page 276).
14. See Locations — Models 830, SB2 system unit with FC 9074 base I/O tower.
Remove the IOPs and IOAs, EXCEPT for the load-source IOP and the first storage IOA.
Attempt to perform the alternate IPL.
Does the same SRC occur?
v Yes: Continue with the next step.
v No: If the system IPLs past the original error, then isolate to the failing IOP or IOA card.
Follow the service actions for the new SRC.
This ends the procedure.
15. Remove (and label) all of the storage device units EXCEPT for the alternate IPL load-source device
unit that you are currently using (This includes all of the disk devices in D31-D40 and D46-D50.)
If the system IPLs past the original error, then isolate to the failing device unit.
If the failure still occurs, replace the following FRUs in order one at a time until the problem is
resolved. See the Remove and replace procedures.
a. Load source IOP in location C01 in the FC 9074 base I/O tower.
b. First storage IOA (location C02, C03 or C04) in the FC 9074 base I/O tower.
c. HSL I/O bridge card in location C08 in the FC 9074 base I/O tower.
d. Network interface controller (NIC) card in location M06 in the 830 system unit.
e. Tower card in location CB1 in the FC 9074 base I/O tower.
This ends the procedure.
16. This is a Model 840, SB3 system unit and FC 9079 base I/O tower.
See FRU locations and failing components for Models 840, SB3 system unit processor tower table.
Remove the IOPs and IOAs, EXCEPT for the load-source IOP and the first storage IOA.
Does the same SRC occur?
v Yes: Continue with the next step.
v No: If the system IPLs past the original error, then isolate to the failing IOP or IOA card.
Follow the service actions for the new SRC
17. Remove (and label) all of the storage device units EXCEPT for the alternate IPL load-source device
unit that you are currently using. (This includes all of the disk devices in D31-D40 and D46-D50.)
If the system IPLs past the original error, then isolate to the failing device unit.
If the failure still occurs, replace the following FRUs in order one at a time until the problem is
resolved. See the Remove and replace procedures.
a. Load source IOP in location C01 in the FC 9079 base I/O tower.
