3. Power off the system from the control panel.
Remove the cables and connections from the secondary I/O towers so that HSL
ports A0 and A1 connect only the Base I/O Tower to the System Unit. This is a
minumum configuration for IPL.
Note: The connections to any I/O towers other than those connected to ports
A0 and A1 should not affect this procedure.
Power on the system.
Does the same SRC occur ?
Yes No
↓
Follow the service actions for the new SRC.
If the IPL is successful, then the failing item is in a secondary I/O
tower. Restore the I/O Towers one at a time until the problem is
isolated.
4. Is this system a Model 830 with SB2 System Unit and FC 9074 ?
Yes No
