Cleaning the Interior

One of the most important items in a good maintenance program is regular and thorough cleaning of the interior of the
server, especially around the mother board.
Dust buildup inside the server can lead to several problems. As dust acts as a thermal insulator, a buildup can prevent
proper system cooling. Excessive heat will shorten the life of server components. Also, dust may contain conductive or
corrosive materials that can cause short circuits or corrosion of electrical contacts.
How often you should clean the interior of the server depends on the environment in which it is located. For most office
environments, you probably should clean the server every 12 months. For more severe environments, clean the interior
every 6 months.
Cleaning the interior of the server entails powering off the server and removing the left side cover. You will need a
small vacuum cleaner (with plastic tipped nozzle and electrostatic protection), computer grade canned air, and a small
brush for cleaning the interior.
