Cisco Systems 566 Manual De Usuario

Proper use of preventive maintenance procedures can keep the Content Engine in 
top operating condition and minimize the need for costly, time-consuming service 
procedures. This chapter contains maintenance procedures that you should 
perform regularly.

This chapter covers the tasks required for maintaining a Content Engine or a 
Content Engine farm:

An exhaust fan in the power supply cools the power supply and system by drawing 
air in through various openings in the system and blowing it out the back. 
However, the fan also draws dust and other particles into the system, causing 
contaminant buildup, which results in an increase in the system’s internal 
temperature and interferes with the operation of various system components.

To avoid these conditions, we recommend keeping your work environment clean 
to reduce the amount of dust and dirt around the system, thereby reducing the 
amount of contaminants drawn into the system by the power supply fan.

This section discusses various environmental factors that can adversely affect 
system performance and longevity.
