and rear of the server. Do not place objects in front of the fans. For proper
cooling and airflow, replace the server cover before turning on the server.
Operating the server for extended periods of time (over 30 minutes) with the
server cover removed might damage server components.
When installing the server in a rack, make sure that space is available around
the server to enable the server cooling system to work properly. See the
