External Ambient Temperature Too High
Server component cooling relies on the movement of cool air through the server. The cool air is
pulled into the server from its external environment. If the ambient temperature of the server's
external environment is too high, cooling does not occur, and the internal temperature of the
server and its components increases. This can cause poor server performance or a failure of one
or more components.
Action
: Check the ambient temperature of the server space against the environmental
specifications for the server. If the temperature is not within the required operating range,
remedy the situation immediately.
Prevention
: Periodically check the ambient temperature of the server space to ensure that it
is within the required range, especially if you have 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.
Action
: 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.
Prevention
: Periodically inspect and clean the server vents using a vacuum cleaner. Ensure that
all components, such as cards, cable, fans, air baffles and dividers are properly installed. Never
operate the server without the top cover installed.
Cooling Areas Compromised
To function properly, the server has cooling areas that are maintained by an air baffle,
component filler panels, and the server top cover. These server components need to be in place
