Cooling Issue Description Action Prevention
Temperature
Too High
environment. If the ambient
temperature is too high, the
internal temperature of the
server and its components
increases. This can cause poor
performance and component
failure.
environmental specifications
for the server. If the
temperature is not within
the required operating
range, remedy the situation
immediately.
to ensure that it is within the
required range, especially if
you made any changes to the
server space (for example,
added additional servers). The
temperature must be consistent
and stable.
Airflow
Blockage
The server cooling system
uses fans to pull cool air in
from the server front intake
vents and exhaust warm air out
the server back panel vents.
If the front or back vents are
blocked, the airflow through
the server is disrupted and
the cooling system fails to
function properly causing the
server internal temperature to
rise.
Inspect the server front
and back panel vents for
blockage from dust or debris.
Additionally, inspect the
server interior for improperly
installed components or cables
that can block the flow of air
through the server.
Periodically inspect and clean
the server vents using an ESD
certified vacuum cleaner.
Ensure that all components,
such as cards, cables, fans,
air baffles and dividers are
properly installed. Never
operate the server without the
top cover installed.
Cooling Areas
Compromised
The air baffle, component filler
panels, and server top cover
maintain and direct the flow
of cool air through the server.
These server components must
be in place for the server to
function as a sealed system.
If these components are
not installed correctly, the
airflow inside the server can
become chaotic and non-
directional, which can cause
server components to overheat
and fail.
Inspect the server interior to
ensure that the air baffle is
properly installed. Ensure
that all external-facing
slots (storage drive, PCIe)
are occupied with either a
component or a component
filler panel. Ensure that the
server top cover is in place and
sits flat and snug on top of the
server.
When servicing the server,
ensure that the air baffle is
installed correctly and that
the server has no unoccupied
external-facing slots. Never
operate the server without the
top cover installed.
Hardware
Component
Failure
■ Components, such as
power supplies and fan
modules, are an integral
part of the server cooling
system. When one of these
components fails, the
server internal temperature
can rise. This rise in
temperature can cause
other components to enter
into an over-temperature
state. Additionally, some
components, such as
processors, might overheat
when they are failing,
which can also generate an
over-temperature event.
Investigate the cause of the
overtemperature event, and
replace failed components
immediately . For hardware
troubleshooting information,
see “Troubleshooting
Server Hardware
Faults” on page 23 .
Component redundancy
is provided to allow for
component failure in critical
subsystems, such as the
cooling subsystem. However,
once a component in a
redundant system fails,
the redundancy no longer
exists, and the risk for server
shutdown and component
failures increases. Therefore,
it is important to maintain
redundant systems and
replace failed components
immediately .
