Maintaining the CSACS-1121 Series Appliance
General Exterior Cleaning and Inspection
This section details the cleaning requirements for exterior surfaces of the appliance. It also provides information on
inspecting cables and adapter cards.
Caution:
Never spray cleaning solution on the surfaces of the appliance. Over spray can penetrate into the
appliance and cause electrical problems and corrosion.
Appliance
Use a lint-free, nonabrasive cloth to perform cleaning. Do not use a solvent, abrasive cleaning agents, or tissue paper. If
the appliance is dirty (for example, with thick dust), use a soft damp cloth and gently wipe the surface of the appliance.
Immediately wipe any water or liquid off from the appliance.
Dust and Particles
A clean operating environment can greatly reduce the negative effects of dust and other particles, which act as insulators
and interfere with the operation of an appliance's mechanical components. In addition to regular cleaning, you should
follow these guidelines to deter contamination of the appliance:
Do not permit smoking anywhere near the appliance.
Do not permit food or drink near the appliance.
Cables and Connectors
Periodically inspect cables and connectors to and from your appliance periodically to see if they are worn out or loose.
Adapter Cards
Check the connections on the adapter cards. Ensure that they are secured to the appliance and have not been jarred
loose or mechanically damaged.
Corrosion
The oil from a person's fingers, or prolonged exposure to high temperature or humidity, can corrode the gold-plated
edge connectors and pin connectors on adapter cards in the appliance. This corrosion on adapter card connectors is a
gradual process that can eventually lead to intermittent failure of electrical circuits.
To prevent corrosion, you should avoid touching contacts on adapter cards. Protecting the appliance from corrosive
elements is especially important in moist and salty environments, which tend to promote corrosion. Also, as a further
deterrent to corrosion, the appliance should not be used in extreme temperatures, as explained in the
page 3
section.
Cooling
Exhaust fans in the power supply and in the appliance cool the power supply and the appliance by drawing air in through
various openings in the front of the appliance and blowing it out the back.
However, the fans also draw dust and other particles into the appliance, causing contaminant buildup, which results in
an increase in the appliance's internal temperature and interferes with the operation of various appliance components.
To avoid these conditions, we recommend keeping your work environment clean to reduce the amount of dust and dirt
around the appliance, thereby reducing the amount of contaminants drawn into the appliance by the fans.
