Maintaining the Cisco Wide Area
Application Engine
Proper use of preventive maintenance procedures can keep your system in good
operating condition and minimize the need for costly, time-consuming service
procedures. This appendix contains maintenance procedures that you should
perform regularly.
This appendix covers the following maintenance tasks:
Maintaining Your Site Environment, page C-1

Using Power Protection Devices, page C-7
•
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.
