General Safety Precautions
Follow these rules to ensure general safety:
• Keep the area around the ISS3500 system clean and free of clutter.
• Place the chassis top cover and any system components that have been removed away from
the system or on a table so that they won't accidentally be stepped on.
• While working on the system, do not wear loose clothing such as neckties and unbuttoned
shirt sleeves, which can come into contact with electrical circuits or be pulled into a cooling
fan.
• Remove any jewelry or metal objects from your body, which are excellent metal conductors
that can create short circuits and harm you if they come into contact with printed circuit
boards or areas where power is present.
• After accessing the inside of the system, close the system back up and secure it to the rack
unit with the retention screws after ensuring that all connections have been made.
