(B4FF) System Processor Reference Codes — Instructions for Models 800, 810,
825, 870, and 890
An SRC starting with B4FF indicates the system failed to complete an IPL because
of a processor related problem. Find the full SRC from the list below and take the
indicated action to correct the problem.
B4FF00B0 or B4FF00B1: Indicates a problem with either the Service Processor code
or the load source RIO Bridge.
1. If the SRC B4FF 00B1 occurred after a power outage, remove the incoming
power, wait 30 seconds, reapply the power and retry IPL. If the system IPLs
without the error, the procedure is complete.
2. Load AJDGP01 from RETAIN. IPL the system. If the problem is not corrected,
continue with the next step.
3. Replace the load source RIO Bridge.
v For Models 800 and 810: Replace the System Unit Backplane. See Locations –
Models 800 and 810 for location information, and a link to the remove and
replace instructions.
v For Model 825: Replace the System Unit Backplane. See Locations – Model
825 for location information, and a link to the remove and replace
instructions.
v For Models 870 and 890: Replace the Tower card in the base I/O Unit. See
Locations – Models 870 and 890
4. B4FF00B3: Indicates a problem with a processor or Service Processor code.
Load AJDGP01 from RETAIN. IPL the system. If the problem is not corrected,
follow the instructions for the Model you are working on.
v For Models 800 and 810: Replace the System unit backplane. See Locations –

825 for location information, and a link to the remove and replace
instructions.
v For Models 870 and 890: Replace the MCM module in location M11. See
Locations – Models 870 and 890
6. B4FF00B5: Indicates a problem with a processor or Service Processor code.
Load AJDGP01 from RETAIN. IPL the system. If the problem is not corrected,
follow the instructions for the Model you are working on.
v For Models 800 and 810: Replace the System unit backplane. See Locations –
