SYSUNIT
The failing item is the system processor hardware subsystem.
The system processor (System Unit) has failed and the diagnostic software was not
able to isolate the failure to a FRU.
1. Attempt a SLOW OVERRIDE IPL to run full processor hardware diagnostics.
Power off the system from the control panel. Change the IPL mode to manual,
and the IPL speed to SLOW OVERRIDE (S) using control panel function 2.
Power on the system.
Does the same SRC occur ?
Yes No
↓
Follow the service actions for the new SRC.
2. Is this system a Model 830 with SB2 System Unit and FC 9074 ?
Yes No
↓
Go to Step 4 on page 600 of this procedure.
3.
See “Locations — Models 830, SB2 System Unit with FC 9074 Base I/O
Tower” on page 709.
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.
Note: Be sure to IPL in SLOW OVERRIDE mode after each replacement.
