Cleaning the External Surfaces of the system
Caution:
•
To avoid altering the material and color of the system, do not use
volatile solvents such as thinner and benzene to clean the system.
• The power receptacle, the cables, the connectors on the rear panel of
system, and the inside of the system must be kept dry. Do not moisten
them with water.
For daily cleaning, wipe the external surfaces of the system with a dry soft cloth
If stains remain on the surfaces:
1. Make sure that the system is powered off (the POWER/SLEEP lamp is unlit).
2. Unplug the power cord of the system from a power outlet.
3. Wipe off the dust from the power cord plug with a dry cloth.
4. Soak a soft cloth in a neutral detergent diluted with cold or lukewarm water,
and squeeze it firmly.
5. Rub off the stains from the system with the cloth prepared in Step 4.
6. Soak a soft cloth in water, squeeze it firmly, and wipe the system with it once
again.
7. Wipe the system with a dry cloth.
8. Wipe off dust from the fan exhaust openings with a dry cloth.
Cleaning the Interior of the system
One of the most important items of a good maintenance program is a regular and
thorough cleaning of the inside of the server, especially around the base 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 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.
