Maintaining the Cisco MXE 3000
Proper use of preventive maintenance procedures can keep the Cisco MXE 3000 in good 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 Cisco MXE 3000:
• Maintaining Your Site Environment, page B-1
• Using Power Protection Devices, page B-5
Maintaining Your Site Environment
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.
