Precautions Against Damage To Equipment - Hitachi Compute Rack 220S Replacement Manual

Precautions against damage to equipment

Insertion of foreign objects into the equipment
Do not allow clips, pins or any other metal items or flammable items to enter
the equipment through a vent or by any other means. Continuing to operate
the equipment with foreign objects could cause failure.
Impact from falling
Do not fall the equipment or hit it against another object. It can cause internal
deformation and deterioration. Operating the equipment under such
defective conditions can cause failure.
Vent
A vent is used for preventing rise in temperature inside the equipment. Do
not block the vent by placing or leaning an object. If you do, the temperature
rises, which can cause failure. Check and clean ventilation holes periodically
to keep the dust from gathering on them.
Contact with connection terminals
Do not touch connection terminals, such as a connector with your hand or any
metal item. Do not insert any objects such as wire into them. Do not place the
equipment in a place with metal pieces. If you do, a short circuit can be
developed, causing equipment failure.
Moving between two locations with a temperature differential
When you move the equipment from one location to another, a significant
temperature gap between the two locations may cause condensation on the
surface or inside the equipment. Operating the equipment with condensation
inside can cause a failure in equipment. Leave the equipment at the new
location for several hours until the equipment temperature conforms to that
of the new environment before you start using it. When you move the
equipment from an environment with temperature 5 degrees Celsius to that
with 25 degrees Celsius, for example, leave it for about two hours.
Adding and connecting to peripheral devices
Use only peripheral devices which are explicitly listed as supported in the
manual, and always follow the instructions in the manual. Using devices other
than those mentioned above would cause a failure in peripheral devices and
equipment due to the difference in connection specifications.
