7 MAINTENANCE AND UPGRADES

Maintenance

Preserving Data

Viruses can corrupt files; files can be inadvertently deleted; and hard-disk drives can fail after extended used. To avoid data loss, regularly back up the data files on the hard-disk drive. If you lose the contents of your hard-disk drive, you can reinstall programs, but your data files will be lost if you don’t have a backup. AVG recommends you back up the hard-disk drive at least once a week, with a daily backup of those files that have been changed.

Cleaning System Components

Internal Components

As it draws in air to cool the computer, the power supply fan can also draw dust and other particles into the computer. This debris buildup increases the system’s internal temperature and interferes with component operation and life of the computer.

To avoid this, your Rack Mount Computer has been equipped with a washable air filter. We recommend that you wash this air filter once every 3 months. Change or wash the filter more often if the environment exposes the computer to excessive amounts of dust and debris.

To clean diskette drives, use a commercially available cleaning kit. These kits contain pretreated diskettes to remove contaminants that accumulate during normal operation.

DO NOT attempt to clean drive heads with a swab. You may accidentally misalign the heads, and render the drive inoperable.

External Components

To clean the exterior computer cabinet, perform the following steps:

1.Place a grounding strap around your wrist to reduce the effects of electrostatic discharge (ESD).

2.Turn OFF the computer and any attached devices.

3.Use a small vacuum cleaner to remove any dust from the slots and holes on the computer.

4.Moisten a soft cleaning cloth with a solution of water and liquid dishwashing detergent.
