v Follow the suggested actions in the order in which they are listed in the Action column until the problem is
solved.
v See Chapter 7, "Parts listing for IBM Flex System p260 and p460 Compute Nodes," on page 97 to determine
which components are CRUs and which components are FRUs.
v If an action step is preceded by Trained service technician only, that step must be performed only by a trained
service technician.
Isolation
procedure or
symbolic failing
item Symptom
IOHUB The failing
component is the

Action
Replace the system-board and chassis assembly, as described in
"Replacing the system-board and chassis assembly" on page 83.
Read the description of the system reference code (SRC) and perform any
actions indicated there. If that does not resolve the problem, replace the
system-board and chassis assembly, as described in "Replacing the
system-board and chassis assembly" on page 83.
Replace the system-board and chassis assembly, as described in
"Replacing the system-board and chassis assembly" on page 83.
Replace the system-board and chassis assembly, as described in
"Replacing the system-board and chassis assembly" on page 83.
1. Replace the failing DIMM. See "Removing a DIMM" on page 55 for
location information and for the removal procedure.
2. Install new memory DIMMs, as described in "Installing a DIMM" on
page 58.
For more information, see "Supported DIMMs" on page 59.
1. Check the management-module event log for entries that indicate a
power problem with the IBM Flex System Enterprise Chassis.
2. Resolve any problems.
3. Power off the compute node, as described in "Turning off the compute
node" on page 13.
4. Remove the compute node from the IBM Flex System Enterprise
Chassis, and then reinsert the compute node.
5. Power on the compute node.
6. Monitor the compute node operation to verify that the problem is
solved.
7. If the IBM Flex System Enterprise Chassis is functioning normally but
the 1xxx2647 problem persists, replace the system-board and chassis
assembly, as described in "Replacing the system-board and chassis
assembly" on page 83.
Replace the system-board and chassis assembly, as described in
"Replacing the system-board and chassis assembly" on page 83.
