Action
Replace the CPU/IO module or
a system backboard after
determining where IPMB error
has occurred based on OS
information.
Replace the CPU/IO module.
If updating FPGA does not
help, replace the CPU/IO
module or ft Remote
Management Card (option).
Replace the CPU/IO module.
If turning AC power off and on
does not help, replace the
CPU/IO module or the system
backboard.
Replace the CPU/IO module.
If updating SDR does not help,
replace the CPU/IO module or
ft Remote Management Card
(option).
Replace the CPU/IO module.
If updating SDR/PIA does not
help, replace CPU/IO module.
If turning AC power off and on
does not help, replace the
system backboard.
Replace the CPU.
Replace the DIMM Slot0 (2
DIMMs).
Replace the DIMM Slot1 (2
DIMMs).
Replace the DIMM Slot3 (2
DIMMs).
