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 the server components. The dust may also contain conductive or corrosive
materials that can cause short circuits or corrosion of the electrical contacts.
The frequency at which you should clean the inside of the server depends on the
environment in which it is located. For most office environments, every 12 months is
probably sufficient. For more severe environments, clean the inside every 6 months.
Cleaning the interior of the server implies powering off the server and removing the left
side cover. You will need a small vacuum cleaner (with a plastic tipped nozzle and
electrostatic protection), computer grade canned air, and a small brush.
