Maintaining Your GSS

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

This chapter includes the following major sections:

Maintaining Your Site Environment

Using Power Protection Devices

Maintaining Your Site Environment

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

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