Remove the IOPs and IOAs, EXCEPT for the load-source IOP and the first storage IOA. (Normally
this would mean to remove the cards in locations C02 and C04 - but leave the cards in location C01
and C03.)
Attempt to perform the alternate IPL
12. 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.
13. 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 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
14. See Locations - Models 840, SB3 system unit with processor tower and FC 9079 base I/O tower.

d. Network interface controller (NIC) card in location M17 in the 840 system unit.
e. Tower card in location CB1 in the FC 9079 base I/O tower.
This ends the procedure.
