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.
Does the same SRC occur ?
Yes 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.
8. 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 “Chapter 4. Removal and Installation Procedures”
on page 617.
a. Load Source IOP in Location C01 in the FC 9079 Base I/O Tower.
b. First storage IOA (location C02, C03, or C04) in the FC 9079 Base I/O
Tower.
c. HSL I/O bridge Card in location C08 in the 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.
