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 System Safety Electrostatic discharge ESD is generated by two objects with different electrical charges coming into contact with each other An electrical discharge is created to neutralize this difference which can damage electronic components and printed circuit boards The following measures are generally sufficient to neutralize this difference before contact is made to protect your equipment from ESD Do not use mats designed to decrease electrostatic discharge as protection from electrical shock Instead use rubber mats that have been specifically designed as electrical insulators Use a grounded wrist strap designed to prevent static discharge Keep all components and printed circuit boards PCBs in their antistatic bags until ready for use Touch a grounded metal object before removing any board from its antistatic bag 2 3 SC748 Chassis
