Iop; Iopwr; Iplintf - IBM iSeries Series Hardware Problem Analysis And Isolation

IOP

For use by authorized service providers.
Replace the I/O processor. Use the I/O processor location information in the Service Action Log if it is
available. If the location is not available, find the address of the I/O Processor. See SRC address formats.
Use the address to find the location. See Locations and addresses.
If the failing item is in a migration tower, go to the IOP symbolic FRU in the Migrated Expansion Tower
Problem Analysis, Repair and Parts manual on the V5R1 Supplemental Manuals web site

IOPWR

For use by authorized service providers.
The failing item is a power supply or power subsystem hardware in an I/O tower. See Remove and replace
procedures.

IPLINTF

For use by authorized service providers.
The failing item is any card, cable, card enclosure, or device connected to bus 1 that might cause an
interface failure between the service processor and the load-source device.
1. Perform the following:
a. Power off the system from the control panel.
b. Change the IPL mode to manual, and the IPL speed to SLOW OVERRIDE(S) using control panel
function 2.
c. Power on the system.
Does the same SRC occur?
v Yes: Continue with the next step.
v No: Go to "Starting point for all problems" on page 2 and follow the service actions for the new
SRC.
This ends the procedure.
2. Power off the system from the control panel. Attempt to IPL from a different load source device.
v If the failing IPL was mode A or B from the disk load source, then get an alternate IPL media and
attempt an IPL mode D using the alternate IPL media.
v If the failing IPL was mode D from an alternate IPL media, then use the "LSMEDIA" on page 360
symbolic FRU.
Does the same SRC occur?
v Yes: Continue with the next step.
v No: Follow the service actions for the new SRC.
– If the IPL is successful, then the failing item is the load-source disk device. Slip-install Licensed
Internal Code and attempt another IPL.
– If the failure still occurs replace the load-source disk device unit.
3. The failing item is one of the cards or devices attached to the interface for IPL load-source device(s).
Choose from the following options:
v If you are on a Model 270, 800, or 810: Continue with the next step.
v If you are on a Model 820: Go to step 6 (See page 351).
v If you are on a Model 825: Go to step 8 (See page 351).
v If you are on a Model 830 or SB2: Go to step 11 (See page 351).
v If you are on a Model 840 or SB3: Go to step 14 (See page 352).
