MAN-RCKPC-001 MC100 Series Rack Mount Computer
7 MAINTENANCE AND UPGRADES
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.
