Symptom
Action
FSPSP54
A processor
over-temperature has
been detected. Check
for any
environmental issues
before replacing any
parts.
1.
Measure the ambient room temperature to see if it is in within the
upper limit of the normal operating range. The upper limit is less
than 35 degrees C or 95 degrees F. If the temperature exceeds this
limit, you must bring down the room temperature until it is within
the limit. When the temperature is within range, retry the operation.
2.
If the temperature is within the acceptable range, check the front and
rear of the BladeCenter unit to verify that the each is free of
obstructions that would impede the airflow. If there are obstructions,
you must clear the obstructions. Also clean the air inlets and exits in
the BladeCenter unit drawer as required. If you cleared obstructions,
retry the operation.
3.
Verify that the fans in the BladeCenter unit are working correctly. If
not, replace fans that are not turning or that are turning slowly. If
you replace fans, wait for the unit to cool and retry the operation.
4.
If the fans are functioning correctly, there are environmental issues
with the cooling of the processors. Replace the system board and
chassis assembly, as described in “Replacing the Tier 2 system-board
and chassis assembly” on page 270.
FSPSP55
An error has been
detected on a bus
between two FRUs.
The end-point FRUs
have been called out,
however, the source
of the error could be
the bus path between
the FRUs.
The bus error is corrected by the customer replaceable units (CRUs)
called out after this procedure. Replace the CRUs called out after this
procedure. See Chapter 4, “Removing and replacing blade server
components,” on page 237 for more information.
IOHUB Symbolic
CRU
The failing
component is the
RIO/HSL NIC on the
IPL path.
Replace the system board and chassis assembly, as described in
“Replacing the Tier 2 system-board and chassis assembly” on page 270.
IOBRDG
Symbolic CRU
The failing
component is the
RIO/HSL I/O bridge
on the IPL path.
Replace the system board and chassis assembly, as described in
“Replacing the Tier 2 system-board and chassis assembly” on page 270.
MEMBRD
Symbolic CRU
The failing
component is the
board the memory
DIMMs plug into.
Replace the system board and chassis assembly, as described in
“Replacing the Tier 2 system-board and chassis assembly” on page 270.
MEMCTLR
Symbolic CRU
The failing
component is one of
the memory
controllers.
Replace the system board and chassis assembly, as described in
“Replacing the Tier 2 system-board and chassis assembly” on page 270.
