Troubleshooting System Cooling Issues

Maintaining the proper internal operating temperature of the server is crucial to the health of the
server. To prevent server shutdown and damage to components, address over temperature and
hardware-related issues as soon as they occur. If your server has a temperature-related fault, the
cause of the problem might be:

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
