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.

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.
